(All characters, organizations, places, cases, and incidents...)
(in this drama are fictitious.)
The deceased is a 41-year-old man named Jang Ho Gu.
His car ran into the median strip...
by the entrance under the Mapoong Bridge.
He got married only a year ago,
and his wife also died in a car accident today.
Article 997 of the Civil Law says...
one can receive the inheritance as soon as the other party dies.
My sister is the first person who can claim his inheritance.
Yet they're treating us like we're con artists.
Why don't we ask the NFS to conduct autopsies...
to find out the exact time of death?
Therefore, Jang Ho Gu's time of death is...
is 7:37am.
What about Cha Joo Hee's?
We cannot rule out...
that Cha Joo Hee was murdered.
Pardon?
It's a homicide case now.
What on earth are you saying?
My Joo Hee was murdered?
When we went to inspect the scene of the accident,
we didn't find any skid marks on the road.
It's just as I thought.
There are no skid marks.
How is that important?
She didn't step on the brakes.
Because she didn't slow down when she crashed,
it caused fractures in her cervical spine and a whiplash injury.
On the day of the accident, it was cloudy.
But the concentration of the fine dust was 30 microseconds.
She was more than 200m away from the truck.
If she was watching the road ahead,
she would've stepped on the brakes as soon as she saw the truck.
Why did she not hit the brakes then?
There are 2 possibilities. The 1st one is...
that she was unconscious.
During the autopsy,
we found food remnant in her throat which means she vomited.
I found food remnant in her throat.
Vomiting is one of common symptoms...
before losing one's consciousness.
The second one is that something was wrong with her eyesight.
We found retinal detachment in the deceased's eyes.
When your retina separates, you'll lose your eyesight.
Is that why you extracted her eyes?
Then, which one is it?
- It's both. - We found the substance...
that can cause both in Cha Joo Hee's blood.
(Autopsy Report)
Which part are we supposed to read?
- Darn it. - It's right here.
(Analysis Results)
Right here. We found toxic gas in her system.
That one. N2O.
- Pardon? - It's nitrous oxide.
Nitrous oxide.
When it goes into a body,
it causes hallucination, headaches, and vomiting.
Ocular hypertension causes retinal detachment and hypoxia...
which can lead to loss of consciousness.
The cause of death is the brain damage from the car accident.
But the cause of the accident is the loss of consciousness...
due to the acute poisoning of nitrous oxide.
As for the type of death,
we cannot rule out that she was murdered.
By the way, what's nitrous oxide exactly?
It's for general anesthesia.
It's mostly used in the OR or at the dentists.
And her sister, Cha Do Hee,
is a dental hygienist who gets 1,400 dollars a month.
Forget Tahitian pearls. She couldn't even buy a simple ring.
Now, this case has become a homicide case now.
All of the family members who are present here today...
are important, relevant individuals of this case.
Or suspects even.
And Ms. Cha Do Hee.
- Yes? - You work at a dentist, correct?
- What are you saying? - You fabricated the time of death.
And on top of that, you have...
access to the nitrous oxide which was the murder weapon.
As of this moment,
you've become a suspect of this case.
I will arrest you now since you may try to destroy evidence and flee.
- Right away. - Wait!
- Wait. You can't do this. - What do you mean she's arrested?
What are you talking about? Why are you arresting her?
Why would she kill my daughter?
- What do you think you're doing? - Wait.
- Hold on. - You can't do this!
I thought it was a dispute over inheritance,
but it's a murder case now.
We will investigate thoroughly...
and catch the murderer who killed your daughter-in-law.
As you should.
I doubt she'll have money for a decent lawyer.
You can't do this. Wait!
Please cooperate.
(Partners for Justice 2)
(Maximum Engagement: The point of maximum intrusion in a crash)
You didn't make any mistakes, correct?
What are you implying?
Mom, did you...
- Stop the car. - Okay.
I want you to...
Make sure you don't leave...
The murder weapon of this case is nitrous oxide which is unheard of.
The killer wanted a perfect crime by causing a car accident...
and planned a very elaborate murder.
The culprit is very meticulous...
and has a strong agenda.
The culprit probably carefully planned this for a long time.
And the culprit almost fooled us.
In a nutshell, it means this case is that much harder to crack.
We'll start again from square one and check everything.
- Let's start. - Yes, sir.
Victim, Cha Joo Hee. Age, 27.
She used to be a flight attendant.
She's been a housewife for a year.
He also died on the same day.
Her husband, Jang Ho Gu. Age, 41.
He runs a cafe in a building that he owns.
All right. The first suspect is...
Cha Do Hee, the victim's sister. She's a dental hygienist.
She's a clever woman...
who thought about inheriting her sister's assets...
when her sister had just died in the ER...
and fabricated the time of death for this purpose.
As you all know, she can easily obtain nitrous oxide with her job.
The more I think about it, the scarier this sounds.
She went after her sister's money as soon as her sister died.
That's right. I get why she'd do that.
She's about to get married with Im Jong Min.
She took out money from the savings accounts, had a line of credit,
and gathered every cent she had left.
She literally used up all of her money.
No wonder why she was so greedy over money.
There might've been bad blood between her and her sister...
regarding the inheritance.
What? Settle?
I guess you took a liking...
into that apartment worth four million dollars.
Ho Gu said he'll give it to us...
But here's a thing.
Since a woman from a poor family married into a wealthy family,
she'd be like the golden goose of the family if I'm being blunt.
To the girl's family, this marriage would mean a fortune.
I can't think of any reasons why she'd want to kill her sister.
We're talking about nitrous oxide here.
You need expert knowledge to use the gas to kill someone.
Listen. Once we start digging at the dental clinic,
we'll definitely find a lead.
I'll dig until there's nothing left to dig.
You've got the wrong place.
This case is so obvious.
It's 1 of the 3. Love, money, or grudge.
This case has money written all over it.
Yes, money.
The girl's family is dirt poor.
It's a problem when you don't have money,
but it's also a problem when you have too much.
All right. The second suspect is...
the victim's brother-in-law, Jang Ho Chul.
He ran a car tuning business three years ago which went under.
After his mother paid off the debts, he had to move back in with her.
He's managing her buildings and gets paid 2,000 dollars.
What good is it when his family is rich?
In fact, he doesn't have any assets. He's also dirt poor.
His mother gave his brother an apartment and a building...
when his mother totally neglected him?
This sounds more like it.
Besides, he would be benefitting the most from this accident.
It's just him and his brother.
Since his brother and his sister-in-law died,
he will be the only one who would qualify...
to inherit his mother's assets.
That's only possible because both of them died, correct?
That's right. That's the point.
To Ho Chul, I bet his brother was his biggest obstacle.
But didn't the NFS say...
it was a simple car accident caused by his negligence?
We can't be sure of that yet.
Where is the vehicle now?
Since it's a simple car accident, we didn't impound it yet.
Issue search and seizure warrants for both vehicles.
- Have the NFS inspect the cars. - Yes, sir.
I'll look into Jang Ho Chul's alibi and whereabouts.
And I'll look into Cha Do Hee.
I'll start with the color of her poo on the day of the incident.
I'm going to get to the bottom of it.
There's more.
- What? - What do you mean?
The third suspect is...
the mother-in-law, Cheon Chun Ja.
She has 5 to 6 buildings and tens of studios in Gangnam.
The value of her total assets comes out to 50 million dollars.
She's a rich lady with good assets.
It seemed to me that she wouldn't talk to her in-laws.
Exactly. The economic difference between them is too great.
The girl's family is about to get kicked out for failing to pay rent.
And their in-law is this rich lady with real estate properties...
that's worth millions of dollars.
To people like her, marriage is a business deal too.
I bet she disapproved of the girl.
She could've made them get a divorce.
Why commit murder?
Getting a divorce isn't that simple.
I would say...
there's something between her and her mother-in-law.
Did you see how she didn't even bat an eye...
when her daughter-in-law had died?
Besides, do you really think...
(Jang Ho Chul: 39-year-old Male, Unemployed)
he could have come up with that method?
Cheon Chun Ja is the mastermind behind this?
In that case, we will have to approach her carefully...
with a sufficient amount of evidence.
There is no witness, but three suspects,
and they all have underlying motives and circumstantial evidence...
that even we can't agree on who the sure suspect is.
I think we will have to proceed with simultaneous investigations.
The National Forensics Service discovered the material evidence...
and found out that the female victim was murdered.
So it is our turn to investigate.
Let's work on this case with all our pride.
- Yes, sir. - Yes, sir!
(National Forensics Service)
- It turned out to be a murder? - Yes, sir.
Hey, Fatso, what's going on?
It's just...
We found nitrous oxide in Cha Joo Hee's blood.
Take a look at the autopsy report.
(Autopsy Report)
I didn't hear anything about the car.
They didn't request to check the car
because it seemed to be a simple accident.
Hey,
you're saying it's a murder without even identifying the car?
Are you out of your minds?
And Dr. Sally,
who told you to go there and brief? You're a newbie here.
I was only telling you the facts. Is that wrong?
What?
Sir, we're an organization with procedures for approval.
Are you really going to let them get out of hand like this?
Since they converted the case to a murder case,
they'll send over the car soon, won't they?
Hey,
call the prosecutors this instance! This needs to be gone over again!
(Prosecutors' Office)
Excuse me.
I'm from the Eastern District Prosecutors' Office.
Two vehicles were sent here after accidents on May 15, right?
The two cars under the name Jang Ho Gu are confirmed...
to be involved in a murder case, so we will have to confiscate it.
Oh, those?
This is the sedan,
and they took the SUV away to scrap.
What? Who?
They said the owner died,
so his brother came here about an hour ago.
Here.
(Vehicle Handover Form)
Jang Ho Chul, this jerk. I knew it!
Did he say where he was going?
I wouldn't know.
He knew about the search warrant so he took it away in advance.
I guess he was that desperate.
He must have already gone to Gyeonggi Province.
There aren't any junkyards in Seoul.
But there must be lots of them in Gyeonggi Province.
Gosh, this is driving me crazy!
Let's try the nearby tollgate first.
If he's caught on camera there, we'll be able to narrow our search.
- Thank you. - Sure.
We're from the Eastern District Prosecutors' Office.
Cha Do Hee works here as a dental hygienist, right?
Yes, why do you ask?
She may have gotten involved in a murder case...
that has to do with the hospital's nitrous oxide.
And...
this is the search and seizure warrant regarding the information.
(Search and Seizure Warrant)
Who takes care of the supply and delivery for the nitrous oxide?
Cha Do Hee is the one in charge.
I knew it.
Check the surveillance tape in the parking lot on the day of delivery.
Yes, ma'am.
This is where we store it.
Yes, that's right.
Cha Joo Hee came to pilates class...
every morning at 8:00am.
- Same time every day? - Yes, ma'am.
All right.
If you're so close to your sister,
you must be aware of her daily schedule.
Where were you when Cha Joo Hee...
was at the parking lot getting ready to leave at 7:00am...
on the day of the accident?
Are you suspecting me, her own sister?
How could you...
Most suspects to murders cases end up being a close person.
More than 20 percent is a family member.
My sister...
was the prettiest and smartest trophy child of the family...
and my only friend.
Why would I kill someone like that?
We found nitrous oxide...
in her blood.
And you...
I handle it only for medical purposes in restricted areas.
The day before the accident,
you personally signed for the delivery of 7 10kg-cylinders...
of nitrous oxide.
(Delivered to Cha Do Hee)
Why did you only report six?
That's not the only time.
We've confirmed continuous errors...
between the recorded number and actual delivery...
during your time there.
I'm very busy with work there.
I guess I made some mistakes.
Let's say it was a mistake.
Then why did you load the nitrous oxide in your car?
Prosecutor, I think there's a misunderstanding...
On the day before the accident,
you took a leave at 3:00pm, right?
Did you go visit your sister...
with the nitrous oxide in your car?
No, that's not it.
Then where did you go...
with the nitrous oxide?
- Gosh... - You don't have an alibi...
and we found the instrument of crime.
You are currently the key suspect.
Prosecutor.
Have you ever heard of happy balloon?
Yes.
I heard those balloons are common in the nightlife district.
What they put in those balloons...
is nitrous oxide.
I've been stealing them...
to sell to nightclubs.
I went to a nightclub that day, too.
I needed the money. I'm sorry.
That's it.
I even had plans to have lunch with Joo Hee that day.
Do you think I would have made plans if I was going to kill her?
Prosecutor.
You should be suspecting her husband's family, not me.
They're the ones who killed her for sure!
How can you be so sure?
Those fools couldn't care less about other people when it came to money.
Mother.
I can't believe you.
Did I do something wrong?
You were planning on giving this house away?
I'm so sorry.
It's not what you think.
Ho Gu was only overreacting.
It's a misunderstanding.
Stop harassing my son and get a divorce.
Ma'am, it's a misunderstanding.
I only mentioned that I didn't have a place to live when I got married,
and Ho Gu said he wanted help out.
How pathetic.
Submit the divorce papers.
Ma'am, it's not like that.
Please listen to me...
Mother!
"I'm going to do whatever it takes to set you two apart."
Those were her last words before she left.
They wouldn't even have hesitated to kill her.
We can't be so sure about her testimony.
And she could have made plans with her sister...
on purpose.
Please check the missing amount of nitrous oxide from the dentist...
and the amount sold to the clubs.
All right.
Keep going. Just keep going! Hurry!
Keep going.
Hurry, keep going.
Stop right there!
- Stop! - Keep going!
Stop!
Stop! Wait!
I said, stop!
Gosh!
What do you think you're doing?
What? What's wrong?
I told you to stop!
It was so loud out here.
I couldn't even hear you.
We completely got you red-handed!
Jang Ho Chul.
This car...
will be confiscated as evidence...
from this moment on.
Oh, really?
All right, then. Whatever.
Go ahead.
Gosh...
It's all destroyed, though.
I apologize.
Good luck, then.
Why, that fool!
Are you really going to let him get away?
It's our mistake for being late.
Let's just get the car to the National Forensics Service.
All right.
Didn't you get off of work?
What's wrong with the car?
It was being compressed when they found it.
Let's begin the examination.
Now? Why don't we wait until tomorrow?
No. I'm going to get on it now, so get ready.
Hi, Dr. Baek!
What are you doing here?
What do you mean? This is where I live now.
What about Ms. Eun?
Why don't you forget about your past neighbor?
Aren't you going to work?
Since we're headed the same way, do you want to carpool?
No personal conversations.
- Hello, Baek Beom speaking. - Dr. Baek!
Chief Ma is going to make an important announcement...
about the married couple's car accident case. Come quickly.
Okay.
Did you say you had a car?
Sure.
Hop in.
Elbow in. Window up.
Your arm will get cut off in a car accident.
Take off your sunglasses.
The NFS is 23 degrees southeast from here.
There is a higher possibility of a car accident in the morning...
because of the shortened frontal view due to direct light.
However, these will...
only let 30 percent of visible ray come through.
It won't obstruct the view as it blocks only direct light.
There is a higher possibility for an SUV to turn over than...
It has a higher center of gravity...
and a weaker suspension, so it can be easily turned over.
That's why the center pillar and the side sill are...
fully protected with the high strength plywood.
The pillar will not shift even when it's hit from the side,
so the passengers are perfectly protected.
Happy now?
Shall we go?
Go ahead.
- Dr. Baek, you're here. - There he is.
What is it?
This was so important...
that I stayed up all night as a chief...
to examine the car.
This is the result of the joint investigation...
of the Traffic Engineering Division and the Forensic Medicine Division.
Medical Examiner Baek concluded that the victim, Cha Joo Hee,
was murdered from acute poisoning of nitrous oxide,
which was injected from the outside.
But that was just an assumption made before the car was examined.
Therefore, I would like to take back...
Dr. Baek's opinion.
Hey.
When fuel burns as the car is driven,
nitrogen oxidizes in the air and creates nitrogen oxide.
And nitrous oxide is included in them.
Automobile exhaust is supposed to be emitted out of the vehicle.
And this film prevents the exhaust...
from entering the car from the outside.
But take a look at this.
- There is a hole in the connector. - You're right.
That is why nitrous oxide was brought into the car.
Also,
I cannot agree with that she has been murdered.
If nitrous oxide was injected by another party,
there must be the injection equipment...
that contains nitrous oxide in the car.
However, even if we consider the severe damage of the car,
we still did not find any containers that could have...
held gas in it.
So what's your conclusion?
It's the most logical to say nitrous oxide wasn't injected,
but that it was brought in...
because of a defect in the car.
Therefore, she has died...
an accidental death.
Then what about retinal detachment?
It only shows up with acute poisoning.
When a severe impact is given to your eyeballs,
you may witness retinal detachment.
I assure you with my 13 years of career.
Hey, he's making a tough argument.
What will happen to us?
Exactly. I think he is overly emotional due to lack of sleep.
I am truly sorry as the chief of Forensic Medicine Division...
of the NFS...
for causing a confusion with your investigation...
because of a hasty opinion made by one of our medical examiners.
Are we all done now?
Why did you make a huge scene over nothing?
Let's go.
Gosh, I ran into you.
I didn't see you there.
Sorry.
Darn it, I hate that guy.
The NFS came to a conclusion, so...
Prosecutor Do, give me one second.
- You messed with a wrong guy. - Where are you...
We examined this in many different angles.
We didn't find any instrument of the crime in the car,
so a homicide is just a theory at this point.
Yes, sir. I understand.
Gosh...
Dr. Baek.
Examining the car is the most basic step.
Why did you overreact before you examined the car?
- Let's look at the sedan. - The husband's car?
Why would you examine that? It's all over.
He's overreacting again. I knew it.
Get out if you don't want to watch.
Yes, it must have been stressing you out.
Yes, it's all over.
It's all thanks to you.
I will set up a meeting with the chairman soon.
It'll be an honor to be invited.
See you soon.
Sure. Goodbye.
Gosh, that was close.
You fool.
I did the best I could.
They can't find anything in there because it's totaled...
Shush.
Why are you still here?
Deputy Chief Do.
What about Cha Do Hee?
She said she only sold it to a nightclub,
but that's what she claims.
The books aren't very accurate,
so I cannot find out the amount that was sold and how it was used.
It's too early to stop being suspicious.
An accidental death? An accidental death.
Jang Ho Chul tried to hide the car.
Would he have done that if this was an accidental death?
Gosh, this isn't right.
I'm sure there is something else.
Let's see.
Bloodshot eyes. Dry skin.
And about 0.7cm of eye bags.
Prosecutor Eun, do you get any sleep?
I can't even sleep because my head is full.
You stayed in the night duty room yesterday, didn't you?
- When did you last go home? - Three days ago.
Go home, take a shower, and get some rest.
You need to sleep to make your brain work.
Why are you still here? We're done with this case.
This is why you two were so obsessed with the NFS.
They settled the case once and for all.
All right, let's clear out this old case from the cabinet.
Doctor Jang Cheol.
Tell them.
I came to return the 5,000 dollars...
I took from Ms. Cha's bereaved family.
I'm sorry.
You can deposit the money according to the procedure.
I understand.
- Goodness. - What's up?
Oh, right. We decided to switch houses.
I sent all of your stuff with the moving company.
You can move your furniture on the weekend.
Already?
Sure, a promise is a promise. Goodbye.
(967, Saemal-ro, World Palace, 602, gate code 8901, doorlock 327701)
Gosh. My goodness.
Who are you?
What?
Isn't this...
Dr. Sally's house?
Oh, you'll be using Sally's room?
I'm the H.M. here.
What? H.M.?
The house mate.
Come this way.
This is Sally's room.
Again?
Come on out, Sally's fill-in is here.
I don't need to see her. Forget it.
Follow me.
This is the laundry.
This is the kitchen.
This way.
Room D is in charge of cleaning every Tuesday and Friday.
She lives in room C.
This is the only bathtub in this house,
and room D can use it between 9:30pm to 10:00pm.
Wait a second.
So...
So are you saying...
this is a shared house for four people?
Yes.
What is it?
Was there a burglar?
No.
Then you're the one who made this mess?
That's not important right now.
Dr. Sally, did you just con an incumbent prosecutor...
about a real estate deal?
- I conned you? - It was a share house.
We had to share a bathroom at assigned times.
Yes, that's right.
Then, you should have told me that in advance!
I'm sorry, but I don't think I'd be able to live there.
I'm moving back in.
Gosh, you're picky.
I can hear you, you know.
Give it a shot. People live there too.
Dr. Sally.
You had a fight with your roommates, didn't you?
You don't clean. You're messy. And you do whatever you want.
I get why your roommates would hate you.
Okay. Cool.
I should move out if you want me to.
Let's start packing.
Gosh.
Where am I supposed to go at this hour?
You're heartless.
Forget it.
I'm really exhausted right now.
I'm going to get some sleep now.
You can pack tomorrow.
You didn't even ask for my permission.
This is my house.
Unbelievable.
Okay.
I'm going to get some sleep too.
This sofa is too small.
- Good day. - Hello.
What is this? Did he pass out here yesterday after getting drunk?
Do you think my investigator is a weakling like somebody?
I think he stayed here all night. Let's take our seats now.
What the...
He's not the only one working. Why is he trying to show off?
Let's not wake him up. Why don't we start without him?
- Okay. - Okay.
My leg, my leg. I have a leg cramp.
- Gosh. - Hello.
Hey, you know what?
- I found it. - Found what?
- I found it. - What?
Please take a look at what I found.
Two days before the accident,
he was in the victim's parking lot.
I got him on tape.
Watch from here.
And he stayed in the victim's car for 30 minutes.
- Hey, look. - There he is.
- What? - My gosh.
Gosh, Investigator Yang.
Did you check all the surveillance footage...
from the parking lot all night long?
My job would've been easy if that was it.
The footage from the entrance...
is in bad quality. I couldn't make out the drivers.
So I got a list of unregistered vehicles for the past week.
And I narrowed down to the vehicles that belonged to male drivers.
I looked up every license plate.
And I found the license plate number...
that belonged to Jang Ho Chul.
My gosh, that was so manly. You must be exhausted.
I told you something was there, didn't I?
This part feels really tense. Can you massage this part?
Are your retinas okay? Did they get detached?
- Come on. - Stop it.
The suspect who has a motive for the crime...
showed up at the scene of the crime.
There was a hole in the gasket that prevented car exhaust fumes...
- from entering her car, right? - Yes.
We have just found a possibility that the hole might not be...
a simple defect.
This is enough to make him a suspect.
Then, this was a murder at first and an accidental death next.
And now, this is a murder case again?
Hold your horses.
I've always thought that it was a murder case.
After investigating this case,
my 3.5-percent interest in marriage has vanished.
These in-laws sound so scary. How will I ever get married now?
Mi Ho. That's not exactly why you never got married.
- What's your problem with me? - First of all, bring him here...
as a suspect.
- Yes, sir. - Come on.
- This hurts. - Hey.
What is it this time?
Didn't you close this case as an accidental death?
You've got to be kidding me. I'm a busy man.
Prosecutor Do.
Targeting an innocent civilian...
and coercing him to be present here without a legitimate reason...
is a violation of human rights.
We were going to cover it up with an accidental death.
But what can I do?
Gosh, we found this, you know.
Here.
That was takenon May 13.
That's two days before the accident.
Am I not even allowed to visit my brother?
Of course, you're free to visit him.
But the problem is that...
instead of going to your brother's apartment,
you went to your sister-in-law's car which caused the accident later.
And you didn't just go there.
You stayed there for 30 minutes.
Please explain this.
Who gave you the right to investigate me?
Stop it. Do not speak a word.
As you were informed by the NFS,
the cause of the accident was the defect in her vehicle.
But it makes me wonder why there was a defect...
in the gasket that prevented car exhaust fumes from coming in.
Is it possible that someone rigged the car on purpose?
To cover it up as an accidental death?
Since you ran a car tuning business before,
I'm sure you must know a thing or two about cars.
Didn't you cut off...
the gasket that prevented car exhaust fumes from coming in...
in your sister-in-law's car on purpose?
I can't believe this is happening to me.
Why would I break my sister-in-law's car?
Why would I on earth do that?
Come on. You have ample reason to do so.
Didn't you gain the most from deaths of the couple?
All the assets would go to you if they were out of the picture.
No motive could be stronger than money.
No, that's not it.
Please don't speak. Why don't we plead the Fifth?
Darn it.
If you don't explain what you did in her car for these 30 minutes,
we'll conclude that you may try...
to destroy evidence for the second time and flee the country...
and arrest you right away.
Do you agree as his lawyer?
Okay.
What's happening? What is this?
You should calm down.
What do you mean I should calm down?
Do you think you can calm down now?
Are you telling me to go to the slammer right now?
My gosh, this is driving me crazy.
Come on. I installed a spy cam there.
You don't know anything.
My mother told me to do it.
I didn't kill my sister-in-law.
You can go check. It's in the rear-view mirror.
That's too bad.
You were the one who scraped the car.
No, I mean... Even if it's dented a little...
Gosh, that's too bad.
You destroyed evidence yourself.
Why would I murder my sister-in-law?
Darn it!
I can't believe this is happening to me.
It's her family that murdered my sister-in-law.
Joo Hee was the gold digger. And you know her sister, Do Hee?
She was like a queen bee who mooched off her sister.
Joo Hee, I didn't get the money this month.
Oh, that?
I talked to Ho Gu about it,
but he didn't seem to like the idea.
Your husband's family has 50 million dollars.
To him, 3,000 dollars isn't much. What's his problem?
How are we going to live this month? How will we feed ourselves?
Ho Gu is innocent. You know how innocent he is.
What?
Listen carefully, Cha Joo Hee.
This isn't what we agreed upon. You can do better than this.
Are you kidding me right now? We didn't even start yet.
When he's head over heels for you, you'd better push him for it.
Okay. I already talked to him.
Just give me some time, okay?
You look beautiful.
You're all set.
They flocked to him for the money like a pack of dogs.
Here's what I think. She's more than...
capable of killing her own sister.
It's not me. I didn't kill her.
My client will admit to installing a spy camera...
to record videos illegally.
I know it's too much to ask,
but can you tell the NFS to check...
the rear-view mirror once again and look for the spy cam?
Could you please make that request for us?
- Unbelievable. - No way.
I'll be frank here. How can we know for sure...
that installing a spy cam was the only thing he did?
These secrets don't seem to stop. What messed-up families they are.
Getting the spy cam is our priority.
Call the NFS now. Let's go now.
- Okay. - I got it. This is unbelievable.
- Over here. - Yes, sir.
Did you get it out?
Be careful.
Excuse us.
Here.
I found it! Here it is.
Do you think we'll be able to restore it?
We'll have to check the hardware.
Please get it done as soon as possible.
We even have experience...
of restoring the data from a phone that had been microwaved.
External damage is nothing to us.
What are you doing?
- What? - Hey!
Hey, get out from there!
Hey, what do you think you're doing?
Fatso, did you even get to eat?
Gosh...
Why don't you go and wait for the results to come out?
- Follow me. - Thank you.
Dr. Baek! I counted everything!
There's nothing else left!
There must be something.
Take the airbags out!
Airbags? Gosh...
Take them out!
- Manager Han. - Yes, ma'am?
Have you not been managing the books properly now that Ho Gu is gone?
I'm sorry, ma'am.
You were here.
My client admits to the fact that she installed the illegal spy cams.
She only remained silent to keep the deceased's honor.
My client had a very good reason for it, too.
Since your son confessed to it,
we will need to hear it from you, so please come with us.
Isn't that too much?
All right.
Let's go.
- Manager Han? - Yes, ma'am.
Correct the sales records...
and get all the tax invoices in order by today.
Yes, ma'am.
Let's go.
(Seoul Eastern District Prosecutors' Office)
Wait!
Sorry to have bothered you, Ms. Cheon.
You should have told me earlier.
I'm quite perplexed myself.
Well, why don't you give us your full cooperation and...
This way.
Deputy Chief Do.
Yes?
- You're doing great. - Thank you.
You don't have to go easy on her just because she's my acquaintance.
You know you're not supposed to do that, right?
- Sure, of course. - Make it precise.
As precise as ever.
You guys work with all the evidence,
so don't let anyone push you around.
It's a very important case,
so make sure not to leave anything out of the report...
and have it turned in by the end of the day, all right?
Gosh.
This might even cause a misunderstanding.
I should go now.
Hurry, it's an urgent one.
- What is it? - This one.
- Where? - Hurry up, it's urgent!
- Don't you see that tiny thing? - Where?
Right here! It's on that thing.
Something is dried onto it.
How did you find that?
Hurry up and collect the DNA. We don't have time.
All right.
He's back to being Dr. Psycho.
You installed the spy cams on Cha Joo Hee's car, right?
Well, we had the NFS restore the footage.
Why don't you take a look?
Unfortunately, your son tried to scrap the car,
so we were unable to get the video restored.
However, we did get the audio recordings.
Get divorced immediately,
or you won't be able to keep your honor.
This isn't your first marriage, is it?
You're not even registered in your family. What's up with your family?
Are you all some kind of scammers?
Were you trying to get at our money?
Forget it and get a divorce immediately.
Mother.
I think you mean you want to bring this to court,
but I've prepared something too.
You know who this is, don't you?
Look at you.
So,
what is it that you want?
I want the house to be under my name as well,
and I'd like to send...
a million dollars to my family each month.
You'll do that for me, won't you?
For my baby.
I'm pregnant.
That's unbelievable.
I would've wanted to kill her, too.
Hello, Eun Sol speaking.
Ms. Eun, there was someone with Jang Ho Gu in his car.
What?
- He wasn't alone? - Give that to me.
We found saliva from the airbag of the passenger seat.
We got the DNA from the saliva,
and there was also lipstick and it's a woman.
All right.
You only have suspicions.
Do you have any evidence that I killed her?
Could you get me connected?
All right.
I'm feeling pain here.
Get me some water, Lawyer.
My client has an arrhythmia.
Let's wrap things up here,
and let's get you to the hospital, ma'am.
All right.
Have some water.
You can come on inside.
Okay.
Why do they always have heart problems?
Try breathing in deeply, ma'am.
What do you think you're doing?
We found out that there was a passenger in Jang Ho Gu's car,
and we got the DNA.
We'll have to check if it matches Ms. Cheon's.
What did you say?
What are you talking about?
I thought you had heart pain.
I guess you won't need to go to the hospital.
I guess an evil mother-in-law...
killed an even more wicked daughter-in-law.
It'll be all over when the results come out.
See? I told you it was the mother-in-law.
You were all going for the others,
but my instincts were right.
You owe me 50 dollars.
Gosh, I thought it was going to be Jang Ho Chul.
How can you be thinking of the bet right now?
- What? - Keep your focus, will you?
The results are out.
It doesn't match.
It doesn't?
(DNA Report)
(The DNA sample does not match with the DNA of Cheon Chun Ja.)
(DNA Report)
(The DNA sample does not match...)
(the DNA of Yeom Soon Rye and Cha Do Hee.)
If it's neither Cha Do Hee nor her mother,
and it's not someone from our database,
then who is it?
How do you expect me to know?
- Gosh. - Goodness.
I guess we're going to be the ones to suffer from all the work.
You keep changing your opinions,
and then there's a girl but you don't even know who she is.
What do you want us to do?
We're just giving you the results.
I know, but you just stay at the office and run the machines.
We have to be the ones running around.
Why don't we get going?
- Let's go. - Thank you.
What's the point?
Darn it.
Goodness.
This case is really difficult.
Well, the NSF examination result was completely overturned too.
I thought you moved.
I'm sorry. I moved back.
Look at you two. I knew it.
- No private conversations. - Again?
I'll go. Please do understand. Take care of her.
I'm going to leave too.
We need to have a serious talk.
Yes, sure.
Are you sure you aren't interested in Dr. Baek?
My gosh, you are really fishy.
Do you want some beer?
I don't drink.
You can buy me some coffee.
What kind of coffee do you want?
Half-caffeine ultimate vanilla iced frappuccino,
triple shot, double whipped cream, without ice,
one pump of agave syrup.
Okay. Sure. Fine.
I'd like to order.
Did you memorize all that?
Half-caffeine ultimate vanilla iced frappuccino,
triple shot, double whipped cream, without ice,
two pumps of agave syrup.
Gosh, there it is. Nitrous oxide.
What? What is?
Prosecutor Eun, haven't you worked part-time before?
Nitrous oxide is used in cafes too.
Here is your coffee.
Ms. Han So Ra. Do you remember me?
Yes, you were here before.
May I go in there for a moment?
What?
Your left leg looks very uncomfortable.
Where did you get hurt?
I just fell while working.
Could you undo your top button?
- Why? - I need to check something.
The other side.
That's called a seat belt scar.
No, I just fell.
You're really bad at lying.
You were in the car with him...
on the day of Mr. Jang's accident.
Nitrous oxide.
This is the tool that was used to murder Ms. Cha Joo Hee.
It's something that you work with every single day.
What? No, I...
You need to come with us for a moment.
Ms. Han So Ra.
You are under emergency arrest according to Article 50...
of the criminal law for Ms. Cha Joo Hee's murder.
You can remain silent and refuse to make any statements against you.
You can also consult an attorney.
Goodness.
- Look at this. - Unbelievable.
She used up a lot of these.
I went unconscious. When I woke up...
Ho Gu, are you okay?
Oh, no! No!
I ran away because I got scared.
And you hid this to this day just because you were scared?
Nothing will change even if I told you this.
Why does a manager of a cafe...
need to talk to the owner from early in the morning...
so often before you get to work?
You were having an affair with Mr. Jang, weren't you?
So what?
That gives you a big motive for murdering his wife, Ms. Cha.
What?
No.
No, I...
just met with him a few times...
because he was having such a hard time.
I just lied because I was scared I might get fired...
if his wife found out about our relationship.
You just said...
you ran away because you were scared.
You keep on lying.
Wait.
I've been getting treated for depression,
and this is the medication and prescription.
I'm a patient.
At times, I'm not so good at judging situations.
Do you wish to reduce your sentence...
with physical and mental weakness after you killed a person?
You probably didn't know,
but depression won't help reduce your sentence.
No. No, Prosecutor.
I would have been crazy to mess with that woman.
Mr. Jang and his wife...
wouldn't have lasted long anyway.
Mr. Jang.
Why aren't you going home?
Do you want me to call a chauffeur for you?
So Ra.
I'm really troubled.
What's wrong?
Do you want to listen to this?
Are you...
also treating me like a gold digger?
His wife is...
very tenacious.
If you had hated her that much, you would have wanted to kill her.
Then how will you explain the empty nitrous oxide cartridge,
which was used to kill her?
I just collected the empty ones that we used at the cafe.
And do you have any evidence that it was used to kill her?
Any cafe would have nitrous oxide cartridges.
Someone who has enough motive for murder...
happened to have the main tool of the murder.
And you are lying about the alibi of the day of the accident...
and your relationship with the victim.
And you brought your medical record in case you are found guilty.
We have no choice but to be suspicious of you.
Fine.
I had an affair!
I went to work in Mr. Jang's car every single day.
But do you have any evidence that I killed her?
If you do, tell me.
Tell me!
Oh, gosh.
Han So Ra's DNA from her saliva matches the DNA sample.
And these.
The nitrous oxide...
which killed Ms. Cha.
How can you make someone faint with these?
There are only eight grams in one cartridge,
so she probably needed hundreds.
Then did she take out the gas...
from each one of these, gathered them in a container,
and injected it into her car?
Is that possible?
Is Ms. Cha's SUV still around?
Yes, but you've seen it already.
Let's go.
You want to look into it again?
Let's go.
Gosh, they are absolutely brazen.
They all claim that they didn't do it.
"If you have any evidence, tell me!"
I can't believe how they played innocent.
I'm sure there is the culprit among these rogues.
I know. I got it.
One second. Listen to this.
Okay, Cha Do Hee.
Jang Ho Chul.
Cheon Chun Ja.
Han So Ra.
Maybe these four worked together to kill both of them.
- Goodness. - Come on.
Go write a movie scenario. Sounds like "Murder on the Orient Express".
It's because this is driving me crazy!
Who in the world is the real culprit?
What do you think?
Dr. Baek.
Where did he go?
- Goodness. - Hold it.
Dr. Baek. I thought you were done examining the car.
Hi.
No.
If you're here, help us out.
Wait, is there...
anything else you need to find? What am I looking for?
Everything that's in the car, which wasn't there before.
We took out all the evidence right here.
That's not everything.
Get me a cutting machine. I need to take the truck apart.
What?
Cutting machine.
Goodness.
Pull it out.
Lift it.
Get me the flashlight.
The evidence bag.
Did you find anything?
- What's that? - I know what it is!
Investigator Yang. I need you to find something for me.
The family has admitted to have fabricated...
the death certificate and is asking for forgiveness.
Please forgive them and settle the case with a reasonable demand.
A reasonable demand?
Ms. Cheon.
If my daughter has a criminal record,
she won't be able to get a job.
I would like to give you some settlement money,
but our family doesn't have any money right now.
Although it was brief, you were their family.
- Settle without... - If you keep siding with them,
this mediation won't work.
Family?
We can go, ma'am.
We're from the Criminal Division.
I'm Prosecutor Do Ji Han.
What brings you here?
This won't take long.
We're busy. What is it this time?
We have found out who murdered...
Cha Joo Hee.
(Partners for Justice 2)
Between 5pm to 8pm on Friday,
two murder cases that are suspected...
to have been done by the same killer took place in Bangeo-dong, Seoul.
Could the culprit be killing at this moment?
There's a third murder.
Let me be honest with you.
It's hard for me to control the scene by myself.
I need you to come here. You must be at the scene.
The next one will be at 2am. We only have 30 minutes left.
You're still not done? It's been hours already!
I know that Dr. Psycho is good, but he can pull this one off.
Being meticulous doesn't help us right now.
I'm worried that there will be another victim.
Pieces of a dead body were found at a playground in Bangeo-dong.
Requesting all officers to search the area now.
That wasn't a novel.
