(All characters, organizations, places, cases, and incidents...)
(in this drama are fictitious.)
Let me see.
I can promise you that this wasn't an accident.
There is enough circumstantial evidence to suspect homicide.
You're the only one...
who can find the truth behind this case.
The cause of death. Suffocation due to the paralysis...
of the respiratory system from the neurotoxin.
I got rid of one.
- What's your plan? - We cover up a scandal...
with another scandal.
Celebrity, drugs, and sex.
Look here.
The disease code is snake venom.
Don't you think he's picking a fight with you?
- Who was it? - Yes, Dr. Jang Cheol.
- You can't go home. - What?
Do Ji Han is heading there. You must hide now.
Come back to the office now.
Don't you dare think about going in.
What? He turned down the warrant?
We're right here. We can't just barge in there. What should we do?
What on earth is at this house...
for him to stop me like this?
Let's go back for now.
Darn it.
Let's go, Prosecutor Do.
No, no! Prosecutor Do!
Gosh.
Sir.
This is trespassing. We'll get suspended.
We don't have a warrant either. What do you plan to do?
Darn it. This is getting out of hand.
(Evidence)
Did you get anything from Park Young Soo's clothes?
No. Other than the dirt from the mountain...
and your everyday dust,
there's nothing suspicious.
I scraped off all the substances from underneath his shoes.
But there was nothing special.
- Nothing at all? - No.
Also, we got his prints from the clear rice wine bottle...
that was found at the crime scene.
On the opening,
we found his saliva.
His saliva was the only one we found.
I think he drank it straight out of the bottle.
There's no evidence of a third party?
- Baek Beom speaking. - Dr. Baek.
I need your help.
- What is it? - We're at Jang Cheol's house.
Please examine the scene.
- Okay, give me the address. - Okay.
If you call the NFS as well, things will get out of hand!
What are you planning to do?
I'll take full responsibility.
We can't taint the scene,
so let's wait outside.
My goodness.
Darn it.
Get ready. We're going out.
What?
To where?
You'll find out.
It's urgent.
What about the forensics?
Are they not here yet?
For this case,
they won't come.
Please just trust me and examine the scene.
It looks completely abandoned.
Whose house is it?
It's Doctor K's.
Doctor... Doctor K?
Are you serious?
No wonder.
It looks creepy.
Don't involve your emotions.
Make an objective examination, got it?
Okay.
Let's get ready.
Goodness.
What is this? Did he already pack his belongings and leave?
No.
If there was furniture, there should be traces of dust...
or moving of the furniture.
But there aren't any.
This is how he lived here.
How could a human being live in a house like this?
I'm sure that's why he cleaned up crime scenes.
This isn't an ordinary person's house.
Let's look inside.
What is this?
What? This is the monitoring machine they use at hospitals.
Hold on.
Look at this.
It's covered in dust.
I don't think it was used.
Dr. Baek.
This house... This empty bed...
This is the only drawing she draws these days.
But our bed doesn't look like that.
That's not our house.
This place looks exactly like the drawings Seo Hyun drew.
What are you saying?
Dr. Baek, don't tell me...
that this is Dr. Jang Cheol's house.
Am I right?
- Am I? - You are.
Hold on. You said this was Doctor K's house.
Wait. Does that mean Jang Cheol is Doctor K?
What in the world are you saying?
Check this out.
Isn't this...
Young Soo's crime scene?
It's... It's a snake.
Is he responsible for that incident as well?
But... But there was snake venom.
Did he release a snake there and let it bite him?
- Do you want to try it? - No, thanks.
I think I made a rash assumption. I'm sorry.
The spree killing.
The rope used for hanging.
The layout of the toilet where blood was found.
The fuel that was used for the arson.
He also knew the incident at Sunghoo Motel took place...
in Room 407.
All of this...
wasn't disclosed to the public.
These details can't be known unless he's the culprit.
This is enough evidence.
Since we've found this evidence,
request for a search and seizure post-warrant.
I will get to it right away.
Hold on.
Did you call us over without even getting a warrant?
Well... This was very urgent.
No wonder the forensics wasn't here.
That isn't important.
This is Doctor K's hideout.
He also resigned from the hospital and is off the grid.
- "Off the grid"? - I'm sorry.
- It was too urgent. - Forget it.
Swab and collect everything in this house.
Don't leave anything out.
Dr. Jang...
How could he?
Ms. Han, are you okay?
I knew you were suspicious of him.
- But still... - Soo Yeon.
If you can't handle this, leave.
You should do that. I'll take over.
No. This is a very important place for me as well.
My daughter was here.
I'll help out.
Collect all these pens.
We're going to examine the substances found on his fingers.
"Surgery".
"Forensic Medicine".
"Toxicology".
"Internal Medicine". "Bone-Marrow Transplant".
He has everything.
"Snake Venom".
Is this his mother?
I think so.
She's not smiling...
for her son's graduation photo.
Here.
Look.
Isn't this a bloodstain?
Yes, it is.
Dr. Baek.
There's blood at the center of the crack.
He broke it himself. Swab it.
What? Look here.
They're women's clothes.
This one looks similar to the one his mother wore in that photo.
You're right.
Does that mean...
he's been living with his mother?
No.
He lived here alone.
You're right.
There are no traces of a woman living here.
He said he needed to give his mother her medication.
What do you think he meant?
I don't think there was a patient,
but there are medical appliances here.
He barely has any clothes for himself...
but a lot of his mother's.
Perhaps,
his mother stopped by every now and then.
That's unlikely.
If she was alive,
her shoes must've been at the door.
What?
These are her shoes.
If they're not even living together,
why do you think he has her clothes and shoes?
They're all migalastat.
What kind of drug is that?
It's for Fabry disease.
Patients who lack enzymes or suffer...
from rare congenital diseases take this.
You take it orally.
I requested the warrant.
Seeing how his diary and his shoes are still here,
he must've not had the time to clean the house.
Find out if there was anything strange around this area.
Yes, sir.
Take all the drugs,
and find all traces of his stay here.
(Partners for Justice 2, Episode 14: Missing Link)
(Originated from fossils and evolution,)
(it means something that has not yet been resolved or discovered.)
What?
Dr. Jang Cheol is Doctor K?
To be frank, although I didn't have any solid evidence,
I did suspect him.
He's off the grid at the moment,
and we're tracking him down.
Do you think he ran away?
- Should we openly search... - Prosecutor Eun, listen carefully.
This case is going to be different from all the previous ones.
I can't explain everything at the moment,
but we shouldn't trust anyone from the Eastern District Office anymore.
Is this all related...
to Sungjin?
But isn't this too much for you to handle singlehandedly?
If you need help, look for Song Ji Soo from...
the Supreme Prosecutors' Office.
Okay.
You're the only one I can trust.
- Please help me. - I'll take care of everything here.
I almost died of boredom back there.
Did you seriously just say that?
Isn't everything resolved?
I can act sorry forever.
What a pathetic punk.
I'll talk for you,
so just look sorry.
- Hey! - Hey!
- Jun Seo! - Jun Seo!
- Jun Seo, I know you're innocent! - Jun Seo!
- Jun Seo! - Jun Seo!
- Jun Seo, we trust you! - We believe you.
They did not find any traces of rape or drugs...
in the body of the woman who was allegedly hurt.
Therefore, my client plans...
to make a cross-action for slandering and defamation.
I hope the false allegations all come out to the light...
and no celebrities become falsely accused...
just because of their fame from this day on.
Mr. Kang, please say a word.
How do you feel right now?
I am sorry for making you worried.
I answered all the questions with sincerity.
Everyone, you need to stop.
- Will you file her for slandering? - Jun Seo!
- Jun Seo! - Move aside!
- Jun Seo! - I love you!
- Hello. - You're here.
When will Chief Prosecutor Do come?
Have you heard from Mr. Yang?
Chief Prosecutor Do...
will not help out with Ms. Ahn's case.
But the case...
blew up so much with the press and all.
No matter how rowdy the outside world gets,
we just have to keep investigating without getting shaken.
Is the initial investigation from Gangdong Police Station here?
Yes, we got it. But it's...
a complete mess.
There was a water leak...
at the server room in the basement of the club,
so all the cameras were turned off. Does that make any sense?
And look at the list of confiscated items.
There are no cameras at all.
They practically gave them time to erase the footage.
Goodness, you all are working so hard.
Hey, the GHB case?
It didn't look too easy.
Oh, I just came to take back my cases.
Why are you taking the files?
Oh, you must've been too busy to hear the news.
I'm returning as a chief prosecutor. Aren't you glad?
- Sure. - Congratulations.
I'm glad I was just reprimanded. That darned pigs' feet.
I quit eating those after that incident.
It was just a joke.
Anyway, let's keep working hard.
Okay, then. Goodbye.
What? He was just reprimanded?
Chief Prosecutor Gal's bullying is...
about to begin again.
Okay, let's not get shaken and continue to investigate.
Mr. Kang, check the initial report with Gangdong Police Station.
Let's start questioning those people who were at the club on that day.
Yes.
Dae means big, Cheol means firm.
I will never get broken.
(Chief Prosecutor Gal Dae Cheol)
You don't have time to be happy about your reinstatement.
This is a request from Do Ji Han, asking for a post-warrant.
A post-warrant?
Yes!
Do Ji Han barged into Doctor K's house without a warrant.
He ended up finding the plan for the spree killing!
That jerk.
I said you won't be able to deal with him once he gets angry.
What if Doctor K...
gets caught by Do Ji Han?
It'll be over for all of us.
Sir.
Don't you get what this means?
- What? - Do Ji Han,
that thorough jerk began to cross over the line.
Dr. Han, are you okay? Dr. Jang and Seo Hyun...
We're busy. Let's just work.
Well, I still can't believe it. My goodness.
His house was a mess too.
The kitchen looked completely untouched.
How did he live in such a place?
I still can't forgive him.
He even killed someone.
I didn't think he was like that.
He killed someone?
Goodness.
Dr. Jang, how did you do that?
Dr. Han, I knew it.
You can't be concerned about him. You can't!
I'm not concerned about him.
Get to work. We have a lot to do.
What's this?
What? Why?
We might be able to find out where this dirt came from.
I compared the dirt from Dr. Jang's shoes at the door...
to the dirt in his mother's shoes which were found in the closet.
They were completely different.
Different?
And the shoes have not been worn in ages,
for so long that the owner's DNA isn't even left in here.
How long has it been?
We can say no one wore these for at least a few years.
That means the dirt found on his mother's shoes is...
from Jang Cheol's past.
Wait, so what does this mean?
Dr. Jang's shoes had...
traces of the city, like asphalt residue.
But the soil left...
on his mother's shoes showed it was from the seaside.
"Seaside"?
There are three different coastlines in Korea,
to the east, west, and south.
But the texture of the soil is different in each region.
So I looked into the neritic sediment...
to find out which coastline it was from.
The organisms and the organic matter...
found in each coastline are different.
So where is it?
The soil found in Dr. Jang's mother's shoes are...
from the South Sea.
Among them, it's probably an area with a mudflat.
The South Sea is too big to look for him!
It's not as big as the East Sea.
"The South Sea".
The South Sea...
There is a way to find out.
Club M-Seven.
Prosecutor Eun, it looks like...
someone in Gangdong Police Station is protecting him.
The GHB case was filed...
to the Women and Juvenile Affairs Division﻿.
But it was suddenly transferred to the Economic Crimes Division.
Why is Economic Crimes Division taking over a sexual crime?
You know that a few people in the police force...
works against the good of people.
People like them are in league with such clubs...
and cover up these cases.
The entire police force is...
slandered by everyone because of a few jerks like them.
Something like this ticks me off the most.
I talked to all of the testifiers,
and none of them saw Ms. Ahn.
See? They already got the story straight.
If they have connections in Gangdong Police Station,
I'm sure they made their employees shut up.
Prosecutor Eun.
The footage of Ahn Ji Hye at the hotel...
just got leaked out all over the internet.
"A video of a gold digger".
It's the most searched word right now.
What? The video got leaked out?
- Yes. Take a look. - Let me see.
(The gold digger who tried to con Kang Jun Seo)
What is this? Everyone can see their faces.
How did this get leaked out?
We're still investigating this case.
I wonder.
Here are the comments.
"There was never a worse gold digger than her."
"You shouldn't have messed with Jun Seo."
"I'm going to disclose who you are to the public."
What if Ms. Ahn's identity gets disclosed to the world?
They even used Kang Jun Seo's fan club.
This is frightening.
My goodness. What are we going to do?
(Ahn Ji Hye)
Hello? Ms. Ahn.
Prosecutor Eun, please help me.
Prosecutor Eun, I'm not a gold digger.
You trust me, right?
Ms. Ahn.
I should have stayed silent.
What am I going to do?
First of all, you need to calm down.
Please help me?
What if everyone finds out who I am?
No one in my life knows about this.
I'm so scared.
Ji Hye, it's me, Mom.
What are you doing in there?
Okay, Mom. I'm taking a shower.
This... This isn't you, is it? Something went wrong, right?
What happened? You need to tell me.
Ji Hye.
(Kang Jun Seo's false accuser, Ahn Ji Hye's personal information)
Open the door. You need to open the door.
This is...
all because the NFS couldn't detect the GHB.
Does the NFS have the result of the second analysis?
Not yet.
(Constituent Analysis Result)
It's out.
(Component Analysis Result)
Darn it! It's negative again.
Man, this is driving me insane.
Dr. Sally, did you stay up all night? Have you eaten?
How can I eat right now?
Is it that tough to detect GHB?
Dr. Jang told me last time...
that even the NFS has never detected it in a human body.
It's a darned drug...
with an amazingly short half-life,
so they disappear very quickly.
There is no other way of proving what she said.
Can you run the test again?
Yes, you said you will try this to the end.
What happened to Park Young Soo's urine test?
Here you go.
(Negative)
(The test subject's urine tested negative for 55 types of drugs.)
- What? You didn't find anything? - No, I didn't.
I didn't find anything. Nothing.
What's wrong with me lately?
Gosh, you showed off like you were the king of medical examiners.
The snake venom brought you down, didn't it?
No, it didn't.
Darn it.
Yes, Ms. Cheon?
Prosecutor Eun, Ms. Ahn is on her way here.
She needs to talk to you urgently.
She's on her way?
What am I missing here?
What is it?
I didn't find anything...
from his blood, stomach, and urine.
What should I check next?
Sir, were you asking me that question?
I'm sure you covered everything.
You're not the type to miss anything.
You're so thorough.
I definitely missed something. I know it.
What did I miss?
Should I bring you some ramyeon?
When you chew something, it promotes brain activities,
so it will help you think.
Do you only think about food? Is that it?
(Analysis Result)
I don't need any of these.
I must check something else.
Get ready for an autopsy.
He starts something whenever I try to have some food. Seriously.
What else are you going to check?
I'm going to check his body fluids.
Everything including the spinal fluid and vitreous body.
We'll start with the vitreous body first.
Get it ready.
Hold it.
I'm holding it.
Now, the spinal fluid.
Dr. Baek, don't we...
only check it when the deceased was a patient with spinal cord injuries?
Did you see it?
If his spinal cords were under anesthesia or not?
No, I didn't.
Flip him.
Spinal needle.
Here you go.
Tell Sally to check for drugs and expedite the test.
Ask her nicely.
Then, you should wrap up and stitch him up.
- Who said we were done? - We got the fluids.
I won't finish the autopsy until we find something.
Got that?
Go and come back.
Okay.
Ma'am.
I'd like to...
stop everything here.
I will drop all the charges against Kang Jun Seo.
I'll pretend this never happened.
Wait, what are you saying right now?
You never know if you haven't experienced it.
I'm about to go crazy right now.
I'm taking a year off from college. I don't know when I can go back.
Don't beat yourself up for it.
This isn't your fault, Ms. Ahn.
Then why must my face get plastered all over the web as a gold digger?
Whenever I go out, I feel as if everything is staring at me...
and they're saying that I'm a gold digger.
I'm about to lose it.
There's no evidence either.
Would you be able to keep going...
if this happened to you?
Ms. Ahn, allow me to be realistic...
about this and share a few words with you.
If you drop all the charges now,
his attorney will see it as a chance...
and sue you for every possible charge...
starting with calumny and defamation and demand...
that you compensate him for damaging his reputation.
He's right.
This fight might not end because you give up now.
We cannot force you.
However, we're doing our best to investigate this case.
Please know that we're trying.
Hello?
Ms. Ahn Ji Hye.
Yes? Who is this?
This is Yoo Tae Jun.
I need to talk to you.
Wash this.
Bleeding in the esophagus.
I found three.
Three abrasions.
How can there be abrasions? Did the inflammation cause them?
Will you keep talking back?
- You're going to keep it up? - I'm sorry.
- Write that down. - Okay.
"Bleeding in the esophagus. Three abrasions."
(Bleeding in the esophagus. Three abrasions.)
What are you up to?
I thought you were done with Park Young Soo's autopsy.
I'm not done. Who said I was?
What did you find from the spinal fluids and vitreous body?
Today must be a day where I find nothing.
I didn't find anything again.
Again?
Dr. Baek, I barely managed to get out...
when Dr. Ma left for a bathroom break...
to tell you the result.
Don't think about giving me more work today.
Dr. Baek, is it possible that this man died from a snake bite?
Postmortem angiography.
No abnormal symptoms from the 3D bone reconstruction.
We didn't find any known drugs...
from his blood, urine, vitreous body, and spinal fluids.
No lesions found in his heart, liver, stomach,
and other major organs.
No damage from his brain that could cause him to die.
Nothing at all.
Why? Why can't we find anything?
Dr. Baek.
Mr. Park Young Soo,
What on earth happened?
Dr. Baek, who are you talking to now?
Did you just ask Mr. Park?
Darn it. This is crazy.
He's trying to communicate with the corpse now.
I get that we didn't find anything, but you can't do this.
- What? - Yes?
I was talking to myself. Got it?
I can't even talk to myself?
Scalpel.
(Episode 28)
Why did you call me when I'm busy?
You know him, right?
What a handsome man.
- Who is this? - Jang Cheol.
But you guys call him Doctor K.
You remember, right?
Im Ha Soo.
On May 13th, in a container box in Incheon,
you called Doctor K with your phone...
and told him to come over.
Am I correct?
What's your relationship?
I told you before.
I have no idea who he is.
Hey.
You're the second-highest member of Choonsang Gang.
You were born in Beolgyo in 1978.
- Beolgyo is your hometown. - So what?
Beolgyo.
The southern coast. Mudflat.
Beolgyo is also...
Jang Cheol's hometown, isn't it?
I don't know.
We're done here.
Sit down, you scumbag.
Sit back down.
Don't turn him into a Doberman again.
You do know Dobermans, right?
Once they bite down, they never let go.
This is hilarious.
You've already put me behind bars, so what do you want?
Im Ha Soo.
Weren't you sentenced to five years in prison for drug trafficking?
- So what? - After 4 years and 8 months,
you'll be exhilarated.
Like a short-timer, you'd be dying to get out.
And around that time,
I'll add mediating in drug trafficking to your crimes.
They'll add seven more years to your sentence,
and you'll make a U-turn back to prison.
- Do you still not know? - You're driving me insane.
What am I supposed to say if I don't know anything?
Every time you say that, I'll add one more.
All right.
We can keep going.
Why are you doing this to me?
You even manufactured illegal drugs.
I'll keep this safe until you're pretty much dying to get out.
After that, I'll slide this one in.
With these many charges,
you'll at least get a decade.
Do you still not know?
Why are you suddenly looking for him?
There was a civil servant working at the NTS...
who was looking into a large company.
He was also expecting a child next month.
But he died yesterday.
He died?
He was murdered...
by Doctor K.
Doctor K isn't a murderer...
who kills people.
You must not know him well.
You're wrong!
Cheol won't do such a thing.
Tell me everything you know about him,
how you two met,
and his past.
Tell me chronologically.
That kid...
was my neighbor when we were young.
Cheol.
Come here. Hide over there.
Where's my son?
You saw him, didn't you?
He ran over there.
Jang Cheol. Son.
Cheol. She left.
Hey.
Did your mom hit you because you came second in school?
My gosh.
Why is your mom so greedy?
Gosh, she frightens me.
Did you get hurt?
I got slashed.
You can't leave it like that.
It'll get infected.
My gosh, you're really good.
You're a doctor.
Make sure you become a doctor when you grow up.
He was extremely smart.
But you see,
I can't reach him these days.
Just spill everything already!
I did! This is everything!
Why you little...
That's enough.
Tell me the address to his old house.
Will you please do your job properly?
What's wrong?
Why is Park Young Soo's body still at the NFS?
Baek Beom has been conducting the second autopsy for four hours now.
What?
He already conducted one.
He's doing it all over again.
You know him, right?
Nothing can stop his determination.
He's really annoying me now.
If he finds something out, there's no way for us to get out.
Don't you remember what happened during the spree killing?
Please do your job properly.
Hey.
Did you just order me around?
Sungjin convinced the Ministry of Justice to lift...
your suspension so that you'd do your job. Do you understand?
Fine.
Darn it.
(National Forensics Service)
(Seoul Eastern District Prosecutors' Office)
We're going to conduct a biopsy...
on his bite mark again.
- Scalpel. - Dr. Baek.
You've already done it three times, and we found nothing.
What does "autopsy" mean?
It's what we're doing right now.
It means to confirm something with your eyes.
Scalpel.
Embedding cassette.
Dr. Baek.
Let's follow the formalities.
- Stop the autopsy. - What?
Park Young Soo's case was concluded as an accident.
We also withdrew the request for an autopsy this morning.
Despite that, you're performing another autopsy again.
What should we do?
What do you think? We should finish what we've started.
We shouldn't do this without their permission.
What are you saying? We'll get in trouble.
Turn the speaker off and lock the door.
I can write a written apology later.
Stop it.
Dr. Baek.
You're always levelheaded when conducting an autopsy.
But you're unlike yourself right now.
Why are you acting this way?
Should I just give up when I haven't found anything?
If you haven't found anything after 10 hours,
that means you've done enough.
Director Park,
please take Dr. Baek outside.
You know very well what'll happen if you conduct an autopsy...
without a prosecutor's approval, don't you?
- Confiscate the body. - Yes, sir.
No!
Dr. Baek!
I need...
to suture his ankle before the body gets transferred.
Don't you remember what you told me?
"A body should look more beautiful post-autopsy."
Right.
That's the rule.
I won't allow his family to see him in this state.
All right, then. Suture up.
- Suture. - Okay.
Cut.
Confiscate the body.
- Yes, sir. - Yes, sir.
We couldn't get a sample of his tissue. What should we do?
Where's the suture? Bring it to me.
- Why? - Just bring it. Hurry.
Here.
- Embedding cassette. - Embedding cassette?
Bring it over before this gets damaged.
Okay.
What is it? My gosh!
Did you get a sample of the tissue while suturing him?
Then did you think I'd let them have the body just like that?
Gosh, you're really the best.
Be quiet. Do it properly.
I don't think you ever give up.
Did you just realize that?
I've always known.
Be careful.
- Store it somewhere safe. - Got it.
Sir, you're always wise with your judgments.
As a civil servant myself, I need to abide by the rules.
Was it nine years ago?
Weren't you working at an NFS branch?
The suspected matricide case.
- "Matricide case"? - Yes.
A medical student in Beolgyo was charged with murdering his mother.
Hey, are you the son?
Wake up.
Don't touch her.
We need to cover the floor with vinyl first.
- Right. - You are very cautious,
so you said the cause of her death is unknown.
But it definitely looked like someone else had killed her.
I couldn't indict that guy...
because of your autopsy result.
And that guy became a doctor.
He was at the NFS recently.
Didn't you recognize him?
- What? - Dr. Jang Cheol.
- It's him. - What?
Figures, you only conducted the autopsy during this case.
Of course, you wouldn't recognize him.
Anyway, why are you bringing this up right now?
Well, it's nothing much.
I thought you should know.
Hey, I planted someone useful at the National Forensics Service.
Baek Beom won't do anything weird now.
Great work. It was a long day.
No.
It's not over yet.
We barely found a connection with a crime syndicate.
289 Changdong-ri, Beolgyo-eup.
Beolgyo.
Beolgyo...
Did you say Jang Cheol came to Hanjoo Hospital in February?
Chief Prosecutor Gal also came to our office last February too.
Before that, he was in Beolgyo Prosecutors' Office.
Hey, you're right. What's going on?
Is it just a coincidence?
A coincidence...
Petechial bleeding.
Edema.
Soft tissue bleeding.
Hemocytolysis.
The typical signs of hemotoxin.
It looks like a murder, but no one made an opinion.
Dr. Baek.
I took out the tissue from Mr. Park Young Soo's ankle.
Okay.
What else are you going to check? We already ran all the tests.
Even you can't do anything with a snakebite.
Are you picking a fight as well?
No, it's not that.
When you perform an autopsy, you pick out the reasons...
for bodily damage, saying that you must think like a culprit.
But it doesn't seem to work...
It's because the culprit is a snake.
Exactly.
It's not like you can become a snake.
Oh, you can probably become an angry tiger,
but not a snake.
Why not?
What?
I can become a snake, can't I?
Yes, but how? That makes no sense.
- Hey, get ready. - Why? Where are you going?
To become a snake.
The snake. It was the snake.
Hey, Dr. Baek. Wait. Wait a second.
Hey, what's going on?
You have three reports to turn in.
Why aren't you bringing any for my approval?
I'll bring it tomorrow. I'm busy today.
Tomorrow? My foot. Where are you going?
Hey, wait.
Hey, what's with him? This is really weird.
He only goes to the autopsy room and his office. Where is he going?
Well, how should I put this?
To become a snake?
What? "To become a snake?"
Well, don't try to read too much into this.
He now gave up living as a human, didn't he?
Okay, fine. He can become a snake...
and eat grass and bugs.
Are you coming?
Goodbye.
Hey! Hey, what about the reports?
Give them to me to approve them!
Chief Prosecutor Gal, a file from the Deputy Chief.
- Deputy Chief Do? - Yes.
(Business Trip Plan)
(Destination: Beolgyo)
Can you get Deputy Chief Do?
Sure.
A business trip? What is this?
Why are you going to Beolgyo?
To follow the whereabouts of Park Young Soo's killer.
It's not the time for you to go around on business trips.
Don't go anywhere for a while. Stay put for a while.
Why?
- Because it's Beolgyo? - What?
Chief Prosecutor Gal.
You came to our office in February from Beolgyo Prosecutors' Office.
And Doctor K also came to Seoul in February.
What are you talking about?
Jang Cheol of Hanjoo Hospital.
He's well-acquainted with you.
Goodness, I have no idea what you're saying.
Okay.
That's why I'm going down there myself. Happy?
Stop right there.
Deputy Chief Do.
I will not allow you to hold any investigations starting now.
Immediately stop all requests for warrants and investigations.
This is an order as your chief prosecutor.
What if I insist on going?
I'll consider that you deserted your workplace if you leave now.
You can be punished for that. Do you realize that?
Is that what you're after? Getting rid of me?
You're the one who crossed the line first.
That's why...
you need to be a good boy and sit within the line.
No.
I must cross over the line to fight someone who went over the line.
What about Prosecutor Eun...
who'll have to take responsibility for the GHB case?
The NFS couldn't detect the GHB from her body,
so our office became idiots who were fooled by a gold digger.
This happened while you left Prosecutor Eun on her own.
Did you even care?
What if...
one of your beloved juniors get hurt again?
Deputy Chief Do! I did not approve your business trip proposal.
If you leave this office, I'll report you for leaving your office.
You can't stop me anymore.
This is an order as your chief prosecutor!
I have no reason...
to follow your order.
Why you...
Prosecutor Do!
Prosecutor Do, did he approve your request?
- Let's get in my car. - No.
I'm going alone.
- What? - I am now...
acting against Chief Prosecutor Gal's order.
I may be reported for deserting my office or a breach of duties.
I can be punished for this as a prosecutor.
What are you talking about?
There is no reason for you to do something so dangerous.
- I'll go alone. - Goodness.
- That's nonsense. Come with... - Mr. Yang.
Soo Dong.
Just listen to me.
I'll take this alone.
Help me out.
Goodness.
Hey.
My gosh, man. I really can't do this.
It has to be a wild snake. It is a wild snake, right?
These are all wild snakes.
I've been able to catch numbers of them lately.
But mamushis are a little more valuable.
A rock mamushi.
A rock mamushi? Let's see.
It's right here.
Goodness! My gosh.
I need some fresh poison.
I can't do this alone.
You need to hold the tube.
Hurry.
What are you doing? Hold it.
I can't deal with snakes. I'm too scared.
You do it. You said you'll become a snake.
I have anti-venom. You won't die. Hold it.
No, you do it.
What are you doing? Hold the tube, will you?
Hurry up.
- Goodbye. - Goodbye.
Let's go.
Sir, how much do you charge for the snake wine?
Do you want a glass?
It's great for your manhood.
Dr. Baek, you're buying snake liquor?
I can't find it.
How on earth did you live?
Mom!
Mom, there is someone in here.
Mom! There are bugs here.
Goodness.
Mom! There are bugs in here.
Mom, please!
Please, Mom! Spare me!
Mother!
Mother.
I got accepted to a medical school.
You have a long way ahead of you to follow in your dad's footsteps.
Yes.
Yes, Mother.
(National Forensics Service)
Darn it. Nothing again.
Dr. Ma!
I didn't find GHB in Ms. Ahn's third blood test.
Nothing again?
This is driving me crazy.
Sally. Let's run this one more time. Last one.
We'd be only wasting the sample.
This is enough for one last test.
Darn it. That darned GHB.
Hey, where are you going?
To get some fresh air.
Sally.
You know how to incubate bacteria, right?
Yes, I've done that a lot in school. What is it?
I need to make a growth medium. Eat up and help me. Okay?
I'm losing it because of GHB.
I'm eating ramyeon before I really lose it.
Are you still on that?
What are you stuck at?
I guess targeting isn't possible with LC-MS.
I'm sure that the metabolome is hiding somewhere, but...
Gosh, is it because I set the number of molecules too low?
How can you do a single extraction with LC-MS?
Your initial approach was wrong.
Do you not trust...
You're right. My approach was wrong.
Then which approach should I use?
Since the number of molecules is low, should I give up...
You must run it through a test...
that's more sensitive and selective than LC-MS.
No such test exists.
No, it does! It's way smaller than the molecules!
I can check that first!
Darn it. We have a lot to do. What are you doing here?
How can you eat ramyeon right now?
Dr. Ma, I found a way.
You did? What is it?
Isotopes. Isotope-ratio mass spectrometry. IRMS.
Dr. Sally, the NFS doesn't have the IRMS machine.
I know where it is.
Hey, it's solved, right? Hurry. I don't have much time.
Okay, cool. Life is all about give-and-take.
Sally, where's the machine? Where is it?
Those two...
Here.
Okay.
- Label it. - Roger.
(Park Young Soo)
(Park Young Soo, Venom)
Give me that.
Here.
My little bacteria, make sure you grow up nice and big.
You're indeed one of a kind.
Pardon? What?
Go back to work.
Okay, cool.
Oh, my head. Where did you learn to drive?
You brought the cooperation notice for the IRMS machine, right?
You bet.
You brought her blood and urine samples, right?
Sure, let's go.
(Seoul Regional Korea Food and Drug Administration)
They have a machine that even the NFS doesn't have?
Yes, everything leaves a trace of isotopes.
IRMS uses them...
to check food authenticity and place of origin for ingredients.
And they use this machine to confirm if ingredients are listed correctly.
"Food authenticity"?
It's a request from the Ministry of Food and Drug Safety.
A lot of honey on the market...
is not real honey, so they want me to fish out the fakes.
The case with the honey?
Bingo.
She's in the dressing room.
Okay. Bring her here once she's done with the makeup.
("News Focus")
The live coverage will begin now.
(Prosecutor Gal Dae Cheol)
- Is that her? - It's her.
Ms. Ahn, please come this way.
Five minutes before rolling. Be on standby.
Kang Jun Seo's drug and rape case's victim,
Ms. Ahn Ji Hye, is joining me at the studio.
I'm sure it must have been a hard decision, but thank you for coming.
Could you tell us your story?
What happened in the hotel room that day?
I...
Did you get the result?
This is the LC-MS result when I ran it with the blood sample.
As you can see, there's nothing special.
And this is the IRMS result.
Target metabolome was...
identified at MS 304.891.
You're speaking English because you're worked up.
Please tell me that in Korean.
This is the metabolome for GHB.
And you cannot erase the trace of isotopes.
We have found definite evidence that GHB was injected in her body.
Then, you're telling us you found GHB in her blood.
Yes, I found it. Crystal clear.
Got it!
We'll be able to arrest Kang Jun Seo right away with this evidence.
We'll get going. Thank you for today.
Ms. Ahn, it's all right.
Please don't be afraid.
I...
was not...
raped by Mr. Kang Jun Seo.
And I have never taken GHB...
or suffer from...
memory loss.
Did you hear that?
Mr. Cha, keep asking her questions.
Get her to talk more in detail.
Yes, Ms. Cheon.
You need to watch the news now!
The news?
Okay.
Then are you telling me that the statements...
you've made so far are false?
I would like to drop all the charges...
I have made...
(The Victim of Kang Jun Seo's Case Recants Her Statement)
against Mr. Kang Jun Seo.
What? What is this nonsense?
What on earth...
is going on?
What's this?
"I'm sorry."
What's this?
It's smudged to the right.
Then...
it means that this person was left-handed.
I should have bought you a better meal.
No.
Hey, Dr. Jang. Do you write with your left hand?
Yes.
(I'm sorry.)
Goodness.
Dr. Baek, wake up.
You're still sleeping?
What time is it?
- It's past 10am. - What?
Hey.
I told you to wake me up at 10:15am.
I'm late.
For what?
For what? Can't you guess?
They are different.
What's different?
These two are different.
We used the same venom from a rock mamushi.
Why are they different?
Do you think all snake venom is the same?
Dr. Baek, you have to look at this.
What is it?
Come this way.
Gosh, it's been ages since I saw someone live in this house.
Let me just take a look around the house.
Sure. Suit yourself.
Yes, Dr. Baek.
Hello?
- Prosecutor Do. - Dr. Baek.
I think we found a possibility that Park Young Soo was murdered.
I knew it.
And I need to tell you something about Jang Cheol.
I think Jang Cheol has a different personality within himself.
So be careful.
Hello?
Hello, Prosecutor Do?
It's been a while,
Mr. Baek Beom.
(Partners for Justice 2)
We've never met before, have we?
You killed Young Soo, didn't you?
I can't disguise this as an accident.
Mr. Baek Beom will find out.
I will execute the search and seizure warrant now.
You're violating his rights.
If you have nothing to hide, cooperate with us.
Either it's Do Ji Han or me. One of us has to die...
for this game to end.
We'll start a disciplinary hearing for Prosecutor Do Ji Han.
- Hold on! - It was concluded as an accident.
- What would you investigate? - What if it wasn't an accident?
Listen. Your story doesn't add up.
What are you doing?
Bite him!
