[ All characters, locations, organizations and incidents appearing ]
[ in this film are fictitious. ]
[ Episode 4 ]
[ How can we help you? ]
What's going on?
What are you doing here?
You little...
[ Kang Su, the gangster who's currently on the run ]
[ with the Butterfly Serial Killer, Jang Min-gi, ]
[ was found dead in an old and abandoned police station. ]
[ There was a butterfly signature drawn on Kang Su's body. ]
[ Therefore, Jang Min-gi is currently the main suspect of the investigation. ]
[ However, the police have no clue about his whereabouts. ]
[ He made a complete fool of us. ]
Cut your nonsense.
You think the culprit is someone else?
How could you say that even after what happened?
- But even after Jang Min-gi's arrest... - Shut it.
I want you off the special investigation team.
What are you doing? Stop wasting time!
We need to catch him before the Provincial Division does.
But sir, wait.
Stay quiet for now. Do you want to get suspended again?
Why would Jang Min-gi kill Kang Su?
How would I know? He's a serial killer.
Maybe he wanted to kill him.
Detective Min, follow me.
- But... - Hurry up!
Okay, sir.
You said Jang Min-gi isn't the culprit. So why...
The same kind of murder occurred even after he got arrested.
The handcart dismemberment case.
[ Today's unsolved case: Handcart dismemberment case ]
Then how did the Butterfly Serial Killer know
that Kang Su was hiding at an abandoned police station?
You're right.
Jang Min-gi escaped with Kang Su,
so it's possible that he knew.
But how did the actual culprit find out?
Do you think Jang Min-gi told the culprit?
We need to find out who he is
and what kind of relationship he has with Jang Min-gi
- It was just a wild guess. - We'll have to do some more research
to find out if Jang Min-gi is guilty or not.
Let's stick to the current subject.
Focus on finding the real Butterfly Serial Killer.
"The truth behind the Butterfly Serial Killer."
"Is Jang Min-gi really the culprit?"
I think we can say that in the preview.
Let's stick to how we do things and trace only the facts.
The Butterfly Serial Murders.
The Handcart Dismemberment Case.
And the two additional murders that occurred after Jang Min-gi's escape.
- Gather everything regarding those cases. - Okay.
- And check every single tip-off. - Got it.
I'm going to go and check something.
- What's your problem? - You cannot enter, sir.
- Why not? Forensics are done. - It's the chief's orders.
- Am I really not allowed to enter? - No.
My gosh, the chief is so annoying.
Jang Min-gi can't be the one who killed Kang Su.
Who could it be?
Who's this?
Hello?
Tak... What? Who?
Oh, the pyramid-scheme hawker?
What's the occasion?
What?
Where in the world is building number 413-4?
[ TEAM BULLDOG: OFF-DUTY INVESTIGATION ]
What are you doing?
I'm just trying to be nice.
My gosh.
To me, it just seems like you're illegally taking photos.
- You followed me, didn't you? - My gosh.
It looks like you're on your way to deliver a parcel.
Let's just each go our own ways.
I'm busy, so I'm off.
"Deliver a parcel"? What's her problem?
My gosh.
Why do I keep listening to that hawker?
Where is Afterlife?
Hey.
[ Afterlife, Funeral Service ]
My gosh, why did she have to be here?
[ Afterlife, Funeral Service ]
What?
What's going on?
My gosh, you startled me.
Did you follow me?
You're the one who follows me around.
I'm here to meet someone.
My gosh, what's this?
Why didn't you tell me to watch the stairs?
My gosh, be quiet.
My goodness.
Do you know this place?
Gosh, this place is so eery.
I do know this place, but it's usually not like this.
Okay, well...
It's too dark right now. Let's turn on the lights.
Where's the switch?
Do you think a corpse woke up?
I think so.
That is, if that really is a morgue.
Yes.
Then am I allowed to scream in this kind of situation?
Let me go and check.
- Wait so we can scream together. - Okay.
My gosh.
What is it?
Why didn't you guys turn on the lights?
Detective Tak.
Has it been an hour already?
What?
I slept so well.
You're so weird.
Is it really comfortable to sleep in there?
I get to see what death feels like.
It helps me clear my mind.
You guys can give it a try if you're interested.
No, I'll pass.
I think my mind will just stop working.
You totally scared me.
What's with this guy?
Do you want me to help you experience actual death?
No, thank you.
I'm going to get changed. Have fun while you wait.
Okay.
Okay then.
Why would he go in there?
Seeing that you're here,
both of you must've figured out the undiscovered crimes.
The Handcart Dismemberment Case.
What?
You both get a point each.
Gosh, will you stop making it sound like we're competing?
It's like you're testing us.
- It was a test. - Are you kidding me?
You wouldn't have taken it seriously if I had just told you.
You both need to check for yourselves to believe something.
Okay, whatever. So what's your point?
Did you bring what I asked for?
What? Wait a minute.
You have something, don't you?
- Let me film this. - Deal.
Shoot me from a low angle. It makes me look taller.
A low angle. Tall height. Got it.
My gosh, just hurry up.
Do you think you're a celebrity?
Gosh, you're even chattier.
You always rush us. Action.
Okay.
His MO has evolved.
When the police were barking up the wrong tree,
the butterfly serial killer has evolved.
[ Firstly, he mutilated the corpses. ]
[ The handcart dismemberment case would be the example of it. ]
Secondly, he dumped the corpses differently.
[ When Jang Min-gi escaped, ]
[ the real culprit committed another murder. ]
[ This time, he dumped the body ]
[ in a bathtub instead of an icebox. ]
But he dumped the fugitive's body
in the icebox again.
Can he go back to his old MO?
No. He may evolve, but he will not go backward.
All right.
The butterfly serial killer didn't kill the fugitive.
It was done by a copycat of the butterfly serial killer.
Wait. That doesn't add up at all.
Just a minute ago, you yapped on and on
about how he evolved.
But only this was done by a copycat?
- Because the victim was a man? - Wrong.
Everything including the victim's gender, the dumping method,
and MO can change.
But never a murder weapon.
Changing a murder weapon he's used to is a very difficult task.
He's right.
Compared to the other victims,
the shape of the fracture on the fugitive's head is different.
It means that the murder weapon is different.
So...
- Director Kang. - Yes?
Can you film me with a bust shot?
That way, viewers can trust me more.
Bust shot and credibility. Okay.
Listen. Concluding that this was done by a copycat
because of the murder weapon might be far-fetched.
Gosh, far-fetched or not.
You should argue after hearing them out first. Action.
What did you say? That was insulting.
Be quiet. The camera is rolling.
Rolling? What's rolling here?
My gosh. Do I continue?
Okay.
From the handprints on the other victims' necks,
I can tell that his thumb is especially thick and short.
But as for the shape of the handprint on this dead body,
it doesn't match.
It's because this killer doesn't have phocomelia.
- So... - Hold on.
- Isn't he just a funeral director? - Darn it.
It said so on the sign.
Limited knowledge can be a dangerous thing.
How can you conclude that with photos without seeing the body?
My goodness, you people seem to take things to the extreme.
There's no middle ground for you.
Don't you know the best medical examiner of the NFS, Lee Ban-seok?
- He used to be somewhat famous. - "Somewhat"?
It's embarrassing to say this myself, but I was the best.
This doctor was the one who helped me on the Ido Pharmaceuticals case.
- Well... - Gosh.
A medical examiner became a funeral director.
You did make quite a big career change.
I moved from a technical profession to the service sector.
To me, all corpses are precious.
Hold on.
If the copycat killed Kang Su,
it also means Jang Min-gi could have killed Kang Su.
Jang Min-gi could have known where Kang Su was hiding.
No. Never.
How can you be so sure?
He has an alibi.
Around the estimated time of Kang Su's death, he was with me.
Min-gi.
How...
Listen to me from there.
You paid my mom's medical bills
and mailed the letters for her. Is that true?
I stopped them from telling you about her death.
- I'm sorry. - Who said you could do that?
Who are you to hold a funeral for her
and stop me from sending her off?
It was what she wanted.
She was worried that you might become unstable.
And who caused her to go through so much pain?
To get my revenge,
I drew the butterfly countless times,
so I won't forget it even for a moment.
I'll kill everyone who's responsible for this.
Nothing will change.
- I'll catch the real culprit. - No.
I don't trust anyone now.
You just wait. You'll be the last.
Wait. There are detectives outside.
Min-gi, there are still...
You just let him get away?
You should have stopped him no matter what.
It happened so fast.
So he's going to get back at people who framed him as the culprit?
Yes.
Anyway, the police are hard at work looking for Jang Min-gi.
We should catch the real culprit and copycat.
Why would I work with you?
I'll work with the cops.
Listen. At a glance,
you might think we're lacking.
But we have everything we need.
We have the best profiler, or so he says,
and the best former medical examiner.
I'm still the best.
Everyone recognizes me as the best.
Wait. It's better for you to stay out of this.
You used to be very close with Jang Min-gi.
Are you sure you can stay rational?
Of course, I'm a professional.
And it's a golden chance
to clear Min-gi's name.
Well, Mr. Detective.
You're the most useless one here.
But then again, we need a lousy cop to put the cuffs on them.
A lousy cop?
Hey.
You're the freeloader here.
What? You're ridiculous.
Did you forget I caught the twin brother, Kim Min-seok,
the police let get away?
The biggest power the media has is its power to move the public.
Anyway, we, the police, will catch the culprits.
Just accept that.
I doubt that.
I'm sure you're not with them.
Didn't you get kicked out when you said
Jang Min-gi wasn't the real culprit?
So that's why
you came here with all the files I asked for.
What? You are a deliveryman.
I didn't get kicked out of my team.
We just had a small argument.
Hey. Why don't you just join us when you have the chance
to use your handcuffs?
We need your handcuffs.
We don't need you, per se.
You're inconsiderate and impolite.
You're always so opinionated and never listen to others.
You have one nasty personality.
Thank you for the compliment.
So what will it be?
Fine.
Let's give it a try.
To be honest, everyone seems lacking
and I can't trust anyone here.
But since we're all here, let's do it. I don't expect much anyway.
Well, this will be causal. Okay?
Gosh, you're so chatty.
He's playing hard-to-get.
Hey. Wait.
But why am I involved in this?
We need a place.
I see. A place.
Oh, right. Before we start our investigation, let me say something.
Starting now, all the expenses regarding the investigation
will be covered by me.
So please gather your receipts and hand them to me.
I'll give you the money on the spot.
You're a real man unlike my first impression of you.
You're a real man.
I see. This is what she meant that you're broke in real life,
but you're rich on paper.
Stop insulting me.
All right. Shall we discuss how we'll proceed with our investigation?
- Shall we? - Yes.
All right. Look.
Here. Take this.
Let me see.
[ Afterlife, Funeral Service ]
We live in the same house. Give me a ride.
People might get the wrong idea. Take the bus.
My bottom is used to fancy seats. The bus seats are a bit too hard.
Put on your seatbelt.
What?
Drop me off on your way home.
Gosh. What is this?
How can you guys be so shameless?
We're not shameless. You're just inconsiderate.
Step on it.
What?
Did you just drop the honorifics?
When did I do that?
I guess his hearing is going bad too.
Your left wing mirror is a bit high.
Adjust it before you drive.
Come on.
I'll see you here tomorrow at 10 a.m.
What? Why would I... Hey
You've got my respect!
Gosh, seriously. He's got the thickest skin of all.
Let's keep going.
Oh, my. Are you coming home together?
Ma'am, we just bumped into each other.
Did you go grocery shopping?
Yes, I'm going to make some fresh kimchi.
Aren't you supposed to be busy working?
Another person died.
How can you be coming home?
How can I sleep at the precinct every day?
The Chief of Police told us to take turns and go home.
That inconsiderate jerk did?
Are you sure you're not suspended again?
I think he got kicked out.
Goodness.
Why would I get suspended again? I just came home to eat.
It's fine if you're not. Why are you raising your voice?
And we have no food at home.
How can there be no food at home?
Did you save food for later or something?
If there isn't, there isn't.
If you don't like it, go get yourself some gimbap.
Don't you care about me, Mom?
I'm your precious son, Mom.
I'll care about you when you bring me money.
Would you like to pay for your mom's love in 6-month installments?
Forget it. I don't want to buy love with money
because I'm worth it.
I'm sorry. My son is so immature.
Gosh, ma'am.
Ma'am, do you want me to make kimchi pancakes?
I'm really good at it.
- Let's eat it together without that guy. - That guy?
Did you just... What? Did you call me "that guy"?
Should we do that then?
- I have some rice wine at home too. - So excited!
Rice wine?
My gosh, they're driving me crazy.
[ OCM ]
[ Butterfly serial murder case ]
[ Handcart dismemberment case ]
[ Cases after Jang Min-gi's escape ]
- What do you think? - It's unbelievable.
It's unbelievable that Jang Min-gi isn't the killer, but there's even a copycat.
The scale of this case is huge.
Who should we catch first?
The real killer, of course.
He's a serial killer who murdered six people.
We can't overlook the copycat either.
To copy the butterfly murder that accurately,
he must've gotten detailed information from someone.
What if some prosecutor or police officer is involved?
Suspicious cooperation between the copycat and the prosecution
or the murder of an escaped convict by the police.
- It could be one of those. - Why do we worry about that though?
We can just catch both.
With just us?
They already want to discontinue our show and cut our budget.
Shouldn't we at least have some coffee while working?
We're going to go after the copycat first.
What about the real killer then?
- Without the real killer, the copycat... - It isn't nothing.
I assigned a competent man for the real killer.
You should record everything while following that lousy cop.
On top of your consultation fee, I'll pay you extra for filming.
I'll take that. And add a set of herb tea and two boxes of facial masks.
Deal?
You're such a sly con man.
- Deal. - Deal.
Now, we're going to catch the real killer and the copycat,
and rewrite the history of investigative journalism shows.
Our names will be recorded in the history of the media.
While we're at it, can we have some coffee?
Everyone, let's do our best
to make a legendary show together!
So that was it.
While you were making a legendary show,
I became legendarily broke.
Oh, my.
Moo-taek.
- Please give me a break. - That's what I'm doing.
Okay. So, are you here for money again?
I was looking at the calendar and oh, my...
I realized yesterday was your payday.
Yes, it was. But that money
already disappeared from my bank account. I'm broke.
Oh, my.
It must be hard for you too.
Yes, it is.
Why do you think I moved from the apartment to a rented room?
All right. So, I'm going to ask you
for only 320 dollars this time.
You little...
You took 320 dollars last time too.
I really don't have any money. Do you want me to show you my balance?
What?
What...
As you already know,
even if your balance is zero,
you can still get a cash advance with your credit card.
Of course, with your credit score,
the annual interest would be over 22 percent.
But it's quite useful when you're out of cash.
Would you share the chance to use it with me?
Are you serious?
I told you I'm sorry.
- Oh, my. - Hey, Kang Moo-taek.
Oh, dear.
Hey, did you bring it?
The chief took you off the case.
I'm not sure if I should give you information on the victims.
Who is he, and why is he filming us anyway?
Oh, right. He's the former police who came with the Fact Bomb lady before.
Tell the Section Chief I'm investigating the serial rapist case.
Oh, right. I have huge information.
You know, the killer's blood was found on Lee Seon-mi's teeth.
- Right, did they find the DNA? - No.
The blood sample got mixed with the victim's saliva
so we failed to find the DNA because of the contamination.
But they still got the XY chromosome.
That means the killer is definitely male.
Then we can find out the killer's surname.
- Yes. What? - The killer's surname?
You know, family names such as the Gwangsan Kims and the Hansan Lees.
In general, you take the male's family name,
so you can find out his surname by analyzing the Y chromosome.
That's right. Anyway, isn't that amazing?
I'm sure it's Jang though.
You know that I'm your partner, right?
Don't cheat on me and keep me posted, all right?
You need a beating.
Let me make you come to your senses.
Come here.
Call me as soon as you get the result.
Yes, sir.
It can't be Jang, can it?
Let's go.
[ OB-GYN, pediatrics, internal medicine ]
Why are we here?
This is the hospital where Lee Seon-mi worked.
Since the killer murdered Lee Seon-mi
as soon as Jang Min-gi escaped,
there must be a reason why he chose her as his victim.
Correct.
Getting information about the victim. That's good.
My gosh.
Do you know how many years I've been a detective?
"Correct. That's good."
Well, it's nice to get compliments.
[ OB-GYN Choi Mi-na ]
Goodness.
I see you hurt your hand.
Oh, it's nothing. A little cooking incident.
I'm good with scalpels, but not with kitchen knives.
Thanks for your cooperation.
So, you were close to the victim, Lee Seon-mi?
Yes, we're around the same age,
and we're both single. So, we had a lot in common.
I was so surprised when I heard the news.
I'm surprised you're not married.
- Sorry? - There are lots of pictures of children.
They're the children I sponsor.
Aren't they all beautiful?
Yes.
What was Lee Seon-mi like?
She was so nice that there wasn't anyone who disliked her.
It's such a shame that this happened to her.
Please let me know if there's anything I can do to help.
- Please catch the killer. - Sure.
She was a single woman
with no friends and family.
She had no hobbies either.
Let alone any bad blood, she had no relationships at all.
Even the victims of the butterfly case
didn't have anything in common.
[ The first victim of the butterfly case, Kim Jin-gyeong. ]
[ A bank clerk. ]
[ Loan counseling ]
Hello.
[ The second victim, Joo Yeon-jeong. ]
- Next patient, please come in. [ - A nurse. ]
[ Joo Yeon-jeong ]
[ The third victim, Shin Young-eun, a civil servant. ]
[ Officer Shin Young-eun ]
It hasn't been paid yet.
[ The fourth victim, Lee Ji-hyeon, a lawyer ]
Okay, bye.
[ And the victim of the handcart dismemberment case, Bak Seon-yeong ]
- Welcome, Mr. Kim. [ - A hostess. ]
Let's go to Danseong.
Danseong? Why all of a sudden?
From what I've researched, Lee Seon-mi also worked
at an OB-GYN clinic in Danseong.
So you want to go to Danseong just like that?
And I see that the second victim of the butterfly case, Joo Yeon-jeong,
also worked at the same clinic at the same time as her.
[ Dream For You OB-GYN ]
So you think the OB-GYN clinic might be
the common ground among the victims?
The urology clinic is in the next building.
We know.
Actually, we're the police.
Can we take a look at your medical records
from 2009 to 2012?
I'm at the clinic where the victims, Lee Seon-mi and Joo Yeon-jeong,
both worked together.
Take a look around.
My gosh.
Stop taking a video of yourself
and start searching the files.
Let's check if we can find any evidence
regarding the culprit.
He's such an attention seeker. Goodness.
What? It's Kim Jin-gyeong.
[ Kim Jin-gyeong ]
Look. It's Kim Jin-gyeong, the first victim.
[ OB-GYN Record ]
Joo Yeon-jeong worked here as a nurse,
and the other four victims were patients at this hospital.
- Hello? - We have the culprit's last name.
What is it?
What did I tell you? It's "Jang".
It has to be Jang Min-gi.
[ Doctor: Jang Do-il ]
"Jang Do-il"?
[ Doctor: Jang Do-il ]
Does Dr. Jang Do-il still work here?
- Dr. Jang? - Yes.
He passed away seven years ago
due to an illness.
What should we do now?
The culprit's last name is "Jang".
We barely found a suspect with that last name,
but he died seven years ago.
Oh, right.
Didn't you check my wrist for a scar
saying I must not be the accomplice?
Someone cut the wires on the security cameras in the building
before Lee Seon-mi got murdered.
And there was a huge burn scar on that person's wrist.
The game has begun.
What? What game?
You're not going to tell me again?
Hey.
My goodness.
Did you do some research on the fugitive Kang Su?
Yes, he was a member of a gang
called "The Lee-Kang Gang".
Their boss is Lee Tae-seong, and Kang soo was the second-in-command.
That's why they're called "The Lee-Kang Gang".
He was arrested two years ago
after a subcontracted laborer fell from a building.
He was found guilty for professional negligence.
You're talking about the Isu case, right? It was a huge issue back then.
[ Our lives are worth so little... ]
[ The prosecutor in charge became the mayor of Seowon ]
because he dealt with that case so well.
So I don't think Mayor Yu has any connections with the gangsters.
Then that means the copycat
most likely has connections with the police.
As they say, the foot of the candle is always the darkest.
Not only did he imitate the crime,
but his hideout was also an abandoned police station.
So it's natural to think he might have connections with the police.
But there's a problem.
It's really hard to meet Detective Seo,
the detective who was in charge of the case back then.
He's so obsessed with finding Jang Min-gi.
Hey, you know Kim Jeong-man, the truck driver in the accident?
- Do we have his wife's number? - Yes. Why?
- Are you going to meet her? - Yes.
Kim Jeong-man and Kang Su used to live in the same neighborhood.
That means there could be a connection between them.
I really don't know what to say.
Thank you for coming.
You guys are the only ones who are kind enough to see him off.
You're the big boss, but you still came here yourself.
His other boss even paid for the funeral
and gave me money for his severance pay.
The company didn't compensate for anything because it was a DUI accident.
Tae-seong gave you money?
Yes. Without that money,
we would've gone broke long ago.
By any chance, didn't the other guys visit?
But she's been sitting there alone for a while now.
Hey, you're that pony... In the hole...
You're that guy with an inhaler.
- Here you go. - Thanks.
Oh, gosh.
Thank you for agreeing to do an interview.
I didn't know how to gather information about the Lee-Kang Gang.
I'll do the interview as long as you don't film me.
Okay, I won't.
You're a TV show director, right?
Yes.
Don't think little of gangsters.
You could really die, you know.
I direct a TV show regarding current events and crimes.
So my life is always at risk.
- You saw me that day. - Yes, in a hole.
You did seem like you've got guts.
But then again, even a gangster
got killed by a serial killer.
Kang Su wasn't murdered by a serial killer.
It was a copycat who tried to imitate the Butterfly Serial Murders.
A copycat?
It's highly possible that the prosecutor or police officer in charge
leaked the information to the criminal regarding the Butterfly Serial Murders.
But I don't think it was the prosecutor.
He wasn't on good terms with the Lee-Kang Gang.
I'm talking about Yu Seong-guk, the current mayor of Seowon.
"Prosecutor Yu"?
Yes.
Who told you Prosector Yu
is on bad terms with the Lee-Kang Gang?
Kang Su got sentenced to ten years in prison
instead of getting probation...
That's because
Kang Su got played for being stupid.
- What's going on? - Kang Su!
[ Year 2010 ]
Come here!
Ten years ago,
Prosecutor Yu announced a second war against crime.
- After that day, - Those jerks.
things started to change in this field.
Gangsters could no longer
maintain a living just by managing a hostess bar.
So people started getting involved in real estate
and redevelopment.
[ The 8th General Meeting of Jinsun Trade ]
[ And with that money, ]
[ they bought businesses, ]
[ and started to act like businessmen. ]
Hello, everyone.
Lee Tae-seong became the head of a big organization.
So he slowly started to show himself for PR.
Meanwhile, Kang Su was the second-in-command.
Therefore, he had to stay hidden.
But didn't those gangsters need support from someone powerful
in order to do legal business?
Prosecutor Yu did just that.
He got along great with Tae-seong, so he helped him from behind.
That's how he was able to get away
with all the illegal crimes he had committed.
But he didn't help them regarding the laborer who died
two years ago.
They put an end to the case
once Kang Su got ten years in prison.
Tae-seong probably paid Jeong-man
to cause an accident with that truck
so he could get rid of Kang Su.
Prosecutor Yu and Lee Tae-seong?
I guess we'll have to check.
Let's all give a big "Hurray" for our mayor, Mr. Yu!
- Hurray! - Hurray!
[ Kimchi-sharing Event ]
- Great work, everyone. - Stay healthy, sir.
- Good luck. - Thank you.
- Great work. - We love you, Mr. Mayor.
Thank you, sir.
Hello, Mayor Yu.
I'm Director Kang Moo-young from "Fact Check".
Do you have time for an interview?
Interviews aren't allowed without prior consultation.
No, it's okay.
I can talk to you for a short while.
Thank you. I'll keep it quick.
Do you know Mr. Lee Tae-seong, the president of Taeseong Distribution?
He greatly supports the projects we carry out for the city's youth.
Then do you know
that Mr. Lee used to be a gangster?
No, I've never heard of that before.
From what I know,
you started a second war against crimes ten years ago.
And you tried to get rid of the Red-Zone Gang
which Mr. Lee was a part of.
No, that's...
I'm sorry. He needs to go now. You'll have to stop here.
Let's go, sir.
He investigated Lee Tae-seong's organization ten years ago.
But he didn't know Lee Tae-seong used to be a gangster?
That doesn't make any sense.
- Hey. [ - Moo-young. ]
[ Someone uploaded a post on our webpage ]
[ about the laborer's death. ]
Really? Then ask that person to meet up.
[ - Okay. ] - Thanks.
- You're amazing. - Thank you.
I'm a civil servant, so I don't want anyone to know.
Then by any chance,
did you happen to see
the subcontracted laborer fall
while you were taking photos like this one?
Yes.
- Just a second. - Okay.
- Here. - Thanks.
[ Everyone. I'm on the 66th floor. ]
I'm going to show you a hot...
What?
What is that?
Wait, what?
So the person who falls here is the subcontracted laborer?
Yes.
- Did you report it to the police? - Of course, I did.
Anonymously though.
The news reported it as an accident, so I couldn't do anything.
I'm a civil servant, so I couldn't risk my identity being revealed.
Even after you reported it, they determined the case as an accident?
My gosh!
What are you breaking all day long? It's distracting.
This is my place!
You're shameless.
Who barged into my office and made a mess?
Including you, the three of us?
Even a dog owns half of its house. Do you have a problem with me?
A dog? What are you saying?
Don't belittle yourself like that.
Mr. Funeral Director
owns about 70 percent.
Gosh, how nice of you to know.
Hey, Detective. Come here.
Even though it looks quite primeval...
Oh, gosh.
...there's no better way than this.
What should I use to get this shape?
It could be a handmade weapon that the killer specially made.
To create such a shape,
it must be something that's related to the killer's job or hobby.
I found him. A burn patient with the surname Jang.
A patient who suffered a third-degree burn
and ended up with burn scars on both arms and upper body.
He's in his 30s, and his surname is Jang.
Plus, he worked at a waste management company
in Danseong in 2009 as a day laborer.
[ Family registry ]
He has an older brother, Jang Do-il.
"Sibling, Jang Do-il."
Jang Do-il?
What? Isn't he the OB-GYN
who treated the patients of the butterfly case?
What's his address?
Parcel delivery.
Oh, hi.
- Are you Mr. Jang Seong-su? - Yes.
I need to ask you some questions.
Darn it!
Jang Seong-su, you...
My goodness.
That crazy jerk. Gosh.
Darn it!
He's so rough.
Hey!
Hey, Jang Seong-su!
Hey, you!
Gosh.
Darn it.
You little...
Jang Seong-su, that jerk. Gosh, it's so annoying.
What? Did you lose him?
- We can't even put an APB on him. - Gosh.
He smacked me in the forehead, so now we can.
Hey, Dae-jin, bring my tools. I'll send you the address.
Darn it.
There.
Is this a butterfly museum or something?
Gosh.
That's right, the butterfly.
It's definitely Jang Seong-su. He's obsessed with butterflies.
There's one more.
What?
Please catch the killer.
This is the OB-GYN.
The butterfly case's suspect, Jang Seong-su's brother
is the prime suspect, Jang Do-il.
And his girlfriend
is a doctor from the hospital where Lee Seon-mi worked at.
This is getting more interesting.
So the girlfriend of a day laborer at a waste management company is a doctor.
They say love has no frontiers.
That's true love.
Gosh.
Are you going to keep calling me out when I'm busy?
What on earth are you...
What? What happened to your forehead?
I got a scratch, punk.
See? You got hurt because I'm not here with you.
I guess your relationship was deeper than I thought.
What are you talking about?
Hey, stop talking nonsense and give me the tools.
Why do you need them though?
I'm going to catch a serial rapist.
A serial rapist? Have you really been investigating that case?
Do you think I'd need the tools for that?
Oh, right.
What is that?
Oh, the special investigation team told us to carry our weapons.
They want us to shoot him if necessary.
Shoot whom? Jang Min-gi?
Yes, because he's a serial killer.
[ Disbursement document ]
- Did you give out the ammunition? - Yes, I did.
Your son is getting surgery today.
- Go see him now. - I'm sorry to leave in this situation.
- I'll come back as soon as possible. - Sure.
[ - No, that's... ] [ - I'm sorry. ]
[ He needs to go now. You'll have to stop here. ]
It's a fact that Mayor Yu handled
the subcontracted worker Lee Su-ho's case
and the butterfly serial murder case
when he was a prosecutor.
[ What? ]
What if it was Kang Su who killed the worker by pushing him off the building
and Mayor Yu covered it up for him?
Did he really have a connection to the Lee-Kang gang?
[ Yu Seong-guk ]
"Yu Seong-guk."
[ You're as refreshing as soda, Mr. Mayor. ]
[ Seowon City is proud of you, Mayor Yu! ]
Kang Su...
"Jeju Hongje Beach"?
"June 6, 2018, 10 p.m."
June 6, 10 p.m.
June 6?
[ Forensic examination and autopsy results ]
"June 6, 10:40 p.m."
[ The defendant is sentenced to ten years in prison for professional negligence. ]
If there's really
a connection between the mayor and the Lee-Kang Gang,
why would he make Kang Su get sentenced to ten years in prison?
I kept thinking about that.
And look at this.
The subcontracted worker died
on the night of June 6, 2018.
But that night, Kang Su was on Jeju Island.
So I thought about it.
What if Lee Tae-seong was the person
who killed this subcontracted worker,
and Kang Su went to jail on his behalf?
But he escaped because he was sentenced for too long,
and Lee Tae-seong killed Kang Su for betraying him.
We'll just have to see if your theory is true or not.
You're going to check now?
I get that you want to protect Jang Min-gi
after hearing that the detectives were given real bullets.
But do you really think he'd come here at this hour?
Is Detective Seo In-jae really here?
His son is having surgery here.
Then I bet you I'm right.
Jang Min-gi was arrested
by Seo In-jae, your section chief.
He'll visit him first in order to take revenge.
Then I guess we'll have to stop him.
Hello, Mother.
Yes.
He fell asleep after checking into the hospital.
It's not a big surgery, so you don't need to worry.
You don't need to come.
I'll call you back.
Hey, it's me.
I think Jang Min-gi is at the hospital.
I want you here right now.
Okay, bye.
What?
Where did he go?
Hey, look. Over there.

Director Kang, you should hide by the entrance.
Don't worry. I won't get in the way.
Suit yourself.
Hey!
Where's Tae-seong?
Sir.
It's rude of you to call our boss like he's your friend.
Don't you agree?
Yong-sik, you've changed a lot.
It's Yong-man.
And why is she filming us?
That's none of your business.
It's time you get a beating.
Take care of them.
- Yes, sir. - Yes, sir.
Director Kang.
Are you doing this because I was the one who arrested you?
You ruined my life!
Jang Min-gi!
No.
Hey... Jang Min-gi.
Put down the knife. Put it down!
Min-gi, don't do this.
Put down the knife.
Put it down.
Cut the nonsense.
You're no different!
No!
Shoot me.
Go ahead and shoot!
No!
