Let's take him to the cops.
Or let's just kill him.
You can cover it up and keep it quiet.
Really?
Do you think you can kill me?
Don't put on airs just because you've killed a few people.
If you can do it, so can I.
Did you load the gun?
No, don't. In Woo, please.
You even begged Yook Dong Sik to save your life.
How dare you point a gun at me?
In Woo.
I'm sorry.
What are you doing?
Please don't harm Ji Hoon.
Then I'll give you everything you want.
What do you think I want?
Daehan Securities and all our affiliates.
Even the slush funds. You can have everything.
What did you say that I had to do to get what I want?
You said I should be strong...
and have the ability to stomp on others.
But you'll give up everything you have...
for this wimp?
Yes. Take everything.
Take what you want,
and I won't interfere with your life again.
So please just spare his life.
Where did you hide Yook Dong Sik?
Is there anything you want to say to me?
Please don't kill me, In Woo.
I'll do everything you ask.
Really?
Then let's see how well you keep your word.
You seem a bit tense, so have a drink first.
(Psychopath Diary)
I wonder why they took him to the hills.
Are they going to bury him?
This is where Chairman Seo's summer villa is located.
Why did Chairman Seo suddenly get involved in all this?
Whatever the case, I'm pretty sure that Seo In Woo came here too.
So we need to hurry up and find Mr. Yook.
My goodness, where is...
Boss! Boss!
Hurry.
What happened?
Well, the thing is...
Seo In Woo...
shot Chairman Seo.
He shot him? With a gun?
How could he kill his own father?
That scumbag is out of control.
Sergeant Shim, you should request backup...
before he gets rid of all the evidence and escapes.
He probably called the cops already.
What?
(Officer Heo)
Hey.
What? Seo In Woo reported something?
He said Yook Dong Sik killed Chairman Seo?
My goodness.
We still have hope.
Seo In Woo didn't see me film everything.
If he really didn't notice anything,
he's probably still there.
You recorded everything, right?
That moment when he confessed that he's the predator killer and...
And I even recorded him killing his own father.
Nice. That means we just need to find the camera.
What was the name of that book where you hid the camera?
"Nightmare".
Yook Dong Sik took it with him?
We're talking about the gun he shot your father with.
Ji Hoon must've been shocked.
Let me explain instead.
I got here a bit late, and the guards were already dead.
And when I ran inside,
my father had already been murdered by Yook Dong Sik.
Right?
In Woo, that means you got here last, right?
Bo Kyung, what are you doing here?
I was nearby, so I came hoping that I could be of help.
As you all know, I was kidnapped by Yook Dong Sik.
I barely managed to escape and come here.
He kept threatening me,
so I ended up telling him that Ji Hoon was here.
I think he wanted to take revenge on my entire family.
- Why didn't you call the police? - I did.
I called right before I got kidnapped by Yook Dong Sik.
If the police quickly dealt with the issue,
we could've prevented this from happening.
- Excuse me. - What's wrong? Are you okay?
I don't think he's in his right mind.
He needs to go to the hospital.
Okay, I understand.
Please take him to the hospital.
"Nightmare".
"Nightmare"?
("Nightmare")
Yook Dong Sik, a serial killer who's currently on the run,
has committed another murder.
The victim was Seo Choong Hyun, the chairman of Daehan Securities.
He was found murdered last night at his summer villa.
According to the police, Yook had a grudge against the company...
for the mistreatment he had received as an employee.
He had already attempted...
to murder Director Seo Ji Hoon, Chairman Seo's second son,
in the past but had failed to do so.
Chairman Seo's funeral will be held as soon as the police...
finish the investigation.
And Daehan Securities urgently gathered the board for a meeting...
and appointed Director Seo In Woo...
The chairman always told us...
to think of every single hardship as a challenge.
He told us to fight our hardships instead of just enduring them.
For all of us, his death...
comes as a shock and a tragedy.
But just like he said, we can't spend our lives mourning.
He devoted his life to growing Daehan Securities.
Now, my brother and I will hold down the fort.
I will be by my brother's side and devote myself into helping...
Daehan Securities take a leap forward.
(Daehan Securities' Emergency Press Conference)
You did well.
Just cooperate until Yook Dong Sik is arrested.
Then I'll let you live in peace.
(Oldest Son Seo In Woo Succeeds His Father)
Did you find the camera?
"Nightmare"!
Nice! That's all we need to...
- It's not there. - What?
The memory card had already been removed when she found it.
Seo Ji Hoon must have it.
That's why he mouthed the title to me.
We must get in contact with Seo Ji Hoon somehow.
How though?
Seo In Woo won't let him out of his sight.
There are people who can help.
(Daehan Securities)
Happy, happy, I'm with you always.
I'm Park Jae Ho of Asset Management Team Three...
Dong Sik? Where on earth are you?
What?
Right.
Sure. Got it.
Who is he talking to?
Isn't he talking to Dong Sik on the phone?
- That's what you heard too, right? - Yes.
So you're saying that Jae Ho...
received Dong Sik's call and now he's here to help.
He's not the type to do that.
Maybe he's being blackmailed.
- What? - Let's follow him for now.
Jae Ho, you look more suspicious than I do.
It really is Dong Sik!
Didn't he just stab him?
- What? - No way. They're just hugging.
Dong Sik!
Look at his face. He's frowning due to the pain.
Let me see you.
Gosh, you look terrible.
He's gazing at his friend one last time...
before he's killed.
You actually seem worse.
I must've made you worry a lot.
See that?
Be quiet, will you? They're just happy to see each other.
Shut it for crying out loud.
I don't think Dong Sik's about to kill him.
He's a psychopath for a reason. I'm not letting him fool us again.
- You're reporting him? - No, wait. Don't.
Guys, lower your voices! They'll hear us.
Exactly.
What...
Who are you? Why do you look like that?
Hello, I am Jang Chil Sung of the Meat Republic Gang...
who currently serves Mr. Yook as his boss.
A gang? See? Even his friend is a thug.
Right...
What about me then?
What the...
You got them good.
That's one crazy story.
So you're saying that you witnessed a murder...
but forgot about it due to your memory loss...
and that the real culprit is Director Seo In Woo?
I know it's hard to believe, but it only proves...
how meticulous he is.
So in order to catch him,
we need your help.
Jae Ho.
Don't be scared.
All right.
Our goal is to secure...
Seo Ji Hoon as the witness and the evidence he has.
As of this moment,
right now,
we are in the same boat.
We'll help Dong Sik, serve justice,
and save Daehan Securities...
from the evil killer.
- We'll do our best. Got it? - Yes!
- Keep it down. - You startled me.
All right. Bring it forward.
Mr. Seo.
Hello, sir.
Goodness. Gosh.
Why are you blocking me?
I have papers that need to be signed.
You can leave them over here.
Here you go.
Unbelievable.
He's completely unapproachable.
They come and go to work together and even to the restroom.
All calls and briefings are relayed to Seo In Woo.
Seo Ji Hoon is locked up in his office with guards at the door.
There's no way for us to approach him.
Unbelievable.
What he described isn't a workplace. It's a prison.
Is there really no way to separate them?
There is one.
We'll summon him to the police station...
to ask follow-up questions regarding his father's murder.
Seo In Woo wouldn't let his brother go there.
He'll come down to the station alone.
He wouldn't want Bo Kyung to talk to his brother.
We can at least separate them.
Are you kidding me? That will never work.
The police have already concluded that Dong Sik killed their father.
We'll have to make it work.
This is how...
Seo In Woo would've begun...
his hunt.
(The mystery regarding Chairman Seo's murder)
Mr. Kim, did you read this?
No way. Did you read the anonymous post?
No wonder. I knew something was fishy.
Unbelievable.
Isn't this the mystery of the century?
- Mr. Choi, did you read it? - My gosh.
- Mr. Park, you must see this. - Check this out.
Yook Dong Sik didn't kidnap Mr. Seo.
It was a deal struck between Mr. Seo and Yook Dong Sik.
- I mean... - If you think about it,
the incident with Yuseong Biomedi...
Get back to work.
What is this?
Today's articles about the murder of Daehan Securities' Chairman Seo.
("Chairman Seo Choong Hyun Victim of Power Struggle...")
("The Hidden Truth Behind D Securities' Chairman's Murder")
("The Cruel Rumors Spreading in the Finance Industry")
So?
We need to investigate the witnesses Seo Ji Hoon and Seo In Woo.
Because of these rumors?
Even if we ask them to come in to answer questions,
they aren't suspects, so we can't force them.
Since Seo In Woo succeeded his father as a result of this,
he'll have to come in.
He'll have to stop these rumors from spreading further.
Shouldn't you focus...
on capturing the predator killer, Yook Dong Sik, right now?
I swear on my badge that I will catch...
the predator killer.
Does Seo In Woo know something?
I only need half a day.
If you call Seo In Woo here,
I can catch the predator killer and close this case.
Are you all right?
Yes.
What is it?
I wanted to ask you something,
so I lied that I was sent by Director Seo.
There are rumors about the chairman's death...
and many things seem suspicious.
What... What about it?
I said everything I know.
What is this?
It... It isn't mine.
It belongs to Shim Bo Kyung. It isn't mine.
What is it?
Are you two scheming something?
The police requested both of you come in for further questioning.
He's here.
What do you think about the rumors spreading on social media?
They're outrageous and not worth even responding to.
However, I came because I couldn't bear to see my father's case...
talked about in such vulgar rumors.
Did Seo Ji Hoon refuse the police's request to come in?
He was too traumatized by the incident and is not well.
I will do my best to cooperate with the investigation on his behalf.
We need a clear explanation.
- Please explain. - Tell us in detail.
Excuse us. Let us through.
When Seo In Woo goes to the station,
he will not leave Seo Ji Hoon to roam free.
He will hide him where he thinks is the safest.
In the company building with all the guards...
It may be his house.
That's right. Yes.
We searched his house before.
Do you think he'll put him in that hospital?
Only Seo In Woo will know.
However, there's a good chance it'll be one of them.
(Ocean's Eleven)
We'll have half a day at most.
We must find Seo Ji Hoon during that time.
- Okay? - Okay.
While Bo Kyung has Seo In Woo tied up...
How may I help you?
We received a tip that this hospital gave patients too much medication...
and exaggerated their diagnoses. May we take a look around?
Do you have a warrant?
Right?
What a coincidence.
(Search Warrant)
Seo Ji Hoon isn't at the hospital.
- What about the document? - I faxed it over.
My dad was getting drugs totally unrelated to his illness.
This is clearly illegal.
Your father?
Didn't you call me here about my father's case?
I'm sure they're related,
as you must know.
I don't understand what you mean.
Please answer me about this document.
How is this something for me to answer?
All I did was recommend my friend's hospital.
I was expecting that. So I scolded your friend.
He sang like a bird.
"Seo In Woo made me do it."
I guess he wasn't that reliable a friend.
Why did he tell such a lie?
I'm baffled.
You didn't know?
Then why did that doctor do that to my dad,
who had nothing to do with anything?
Why...
did they destroy his mind with drugs...
and lock him up in a prison without bars...
I had no idea, and...
I simply...
wanted to protect you...
from a dangerous, sick patient.
Bring that in.
You've never seen this before, right?
It's a lie detector.
We searched everywhere,
but I don't think Seo Ji Hoon is in the company building.
Let's go.
Come on.
Should I really break it down?
If we stop now, it's all over.
We have to see it through.
No turning back, right?
Okay, let's open it.
Seo In Woo, you are 36 years old, correct?
That's correct.
You always called your father "Mr. Chairman," correct?
Yes.
Did you always consider your father your patriarch...
and seek to gain his approval?
I did.
You and Seo Ji Hoon...
have different mothers, correct?
How do you feel about your half-brother?
Haven't you ever thought...
that if you cracked open his head, there would be noodles...
instead of a brain?
What's wrong?
That's a strange question.
Really?
I only asked you that question to find out...
what you normally thought of your father and brother.
You remember this, right?
Isn't that Dong Sik's diary?
You made him believe it was his.
And you used this to make him kill me.
You must've been very happy...
when he got arrested.
But if you read what's written in the diary,
you can see that the writer refers to his father as "the chairman."
He writes about his authoritative father who's also the chairman,
his stepbrother whom he utterly hates,
and his sister and brother-in-law who always love to interfere.
Doesn't that family...
sound very familiar to you?
Do you think I'm the predator killer?
That's absurd.
Then let me ask you a simple question.
Mr. Seo In Woo.
Does this diary...
belong to you?
Answer me!
No.
How are the results?
Are you satisfied?
It's just what I expected.
I don't understand a word you're saying.
Can we take a break?
I have a headache.
(Sergeant Shim)
Hey, Bo Kyung.
How did it go?
He's not in his house either.
Where could he be?
Maybe he has a secret hideout somewhere far away.
where he keeps his tools for murder and other types of collections.
If that kind of place existed, he would've written it in his diary.
But the search team couldn't find anything.
I'm sure he has a secret place of his own.
No, if I were him,
I wouldn't keep a secret hideout somewhere outside.
It's too bothersome and dangerous.
Then do you think there might be a secret space...
hidden in his house?
I think I might be able to find it.
We don't have much time. We have about 30 minutes.
I'll call you back.
Seo In Woo might come here, so please continue to stand guard.
Okay.
If I were Seo In Woo...
If I were the predator killer...
Charles Darwin?
"On the Origin of Species"?
You made him take a lie detector test when he isn't even a victim.
You're being too coercive,
so we'd like to reject the witness investigation.
I could change him into a victim.
Let's talk once you have a warrant.
I'd like to cooperate, but my brother isn't doing well.
So I need to go now.
(Ms. Jo Yu Jin)
- Hello? - Hello, I'm Jo Yu Jin.
What brings you to call me?
By any chance, are you with Director Seo?
He just left.
That's good.
The thing is, Director Seo Ji Hoon asked me to do something.
He asked me...
to tell you something.
(Sergeant Shim)
- Hello? - Is Dong Sik still inside?
- Hurry up and call him. - Okay, just a second.
Just one second.
Boss.
That's strange.
Where did he go? Did he go to the bathroom?
I can't find him.
He's gone?
I knew it.
That means there's a secret space inside the house.
Hello? Sergeant Shim?
Chil Sung, I want you to look for a hidden space inside the house.
Seo In Woo might be on his way, so I'll send Taek Soo there.
- Be careful. - Okay.
Boss.
Are you taking a poop?
Seo Ji Hoon! Seo Ji Hoon!
Will you please wake up?
Seo Ji Hoon! Seo Ji Hoon!
Hey, it's Dong Sik.
You saw the camera I was holding that day, right?
Where's the memory card?
- What? - Where's the memory card?
Oh, that?
My gosh. Let's get out of here first.
You idiot.
Why would you come in here?
It's over for you and me.
Yook Dong Sik,
how are things in there?
Seo In Woo!
Do you like it?
Incredible, right?
Hi.
You're right on time.
Cut the crap and tell me where your brother is.
Bo Kyung?
What's with the gun?
Gosh, get that away from me!
I wanted to make it seem realistic, so sorry about that.
Anyway, have a seat.
We'll grab a cup of tea...
I knew you were out of your mind,
but this is sick.
Put your hands on your head and face the wall.
Where's Seo Ji Hoon?
Where is he?
Check the desk.
Did you think it'd be that easy?
Hold still.
Ji Hoon was too cooperative which made me suspicious.
I asked Ms. Jo to shake him up a bit,
and he took the bait.
What an idiot.
Dong Sik and I were somewhat close for a while,
so I should give him one last chance.
Untie me.
Let me go, you jerk!
Stupid cow.
Ms. Shim, what's going on?
Ms. Shim? Ms. Shim!
What do you think you're doing?
He's been getting...
on my nerves for a while.
He mistook himself for a killer after reading my diary,
but he wasn't able to kill a single person.
It's why I'm suggesting a game.
A game?
I'll let you leave and also help you live in hiding...
which is what the Chairman offered.
Only if you kill Ji Hoon though.
What?
If you don't, I'll kill Bo Kyung instead.
So make a choice.
Will it be Ji Hoon or Bo Kyung?
What do you think you're doing?
Shut it, will you?
Can't you see that I'm trying to save you both?
It's only a deal if both parties can benefit.
That's a load of crap!
Dong Sik, don't let him mess with your head.
If you kill his brother,
he'll kill me too,
and pin all the murders on you.
I did think of that scenario,
but it'll be too big of a mess if you all end up dead.
If I let you live though,
you'll keep coming after me.
That's why I need insurance.
Your antics won't work!
Are you sure? Does Dong Sik have another option?
Get on with it. You're running out of time.
How can I trust you?
Dong Sik!
If you commit murder,
Bo Kyung won't be able to say anything.
She'll have to testify that you killed someone to save her.
You will win your freedom...
and Bo Kyung will survive by promising to stay silent.
It'll bring us all happiness.
I'm sure you already know this from reading my diary,
but the kind of people I most want to kill...
are those like you.
Of course.
Why do you think I let you live this long though?
A scapegoat.
You needed someone to pin your murders on.
That's right.
I became a king thanks to your sacrifice.
My father used to say...
that once you finally wear the crown,
you should only shed blood you can benefit from.
I guess it's time for me to grow up now.
Consider this as me going through puberty.
Dong Sik, don't let him get to you!
Seriously, Bo Kyung.
Are you against him committing a murder...
or the fact that you have to arrest him again?
- What? - See?
They're both not an option, right?
That's why the choice is yours, Dong Sik.
You'll then become my accomplice.
You and Bo Kyung.
Forever.
I can't let Ms. Shim die.
Besides,
you too are a jerk anyway.
What? You're really going to kill me?
Snap out of it, you incompetent loser!
I know you've been wanting to kill those...
that think you're nothing.
Do it.
The first kill may be difficult,
but you'll find out that it's no big deal.
Don't!
- Mr. Yook, no... - Don't.
Good job.
(The door has been unlocked)
See that briefcase by the door?
The items the chairman prepared for you so you could run away...
They're all there,
so take it and disappear.
Boss!
What... What is...
Where's Seo Ji Hoon?
What... What?
What? Why are you looking at me like that?
That hurts like mad.
My gosh.
What happened in there?
I didn't think he'd open the door otherwise.
Seriously.
That hurts.
Dong Sik!
Play dead.
Play dead. Now.
Seriously.
- Darn it. - I treated it the best I could,
so get dressed.
Let's go to the hospital.
Bo Kyung is in danger. We must alert the police.
Yook Dong Sik killed Seo Ji Hoon.
In the process, he found out that Shim Bo Kyung and Seo In Woo...
were in the Daehan Securities building,
and went and killed her.
Seo In Woo, who barely escaped,
lost his brother...
and the woman he had feelings for,
and is traumatized.
This was your plan...
from the start, wasn't it?
Risk management is a fundamental part of doing business.
If you're going to kill me, do it quickly.
No, no.
Yook Dong Sik will come here and kill you.
I need to time it.
You psycho.
I'm hurt.
You brought this upon yourself.
To be honest,
I gave you a lot of props.
Because you were the first and only person...
to realize that I existed and what I stood for.
That's why...
I gave you countless chances. Did you know that?
So you should've stopped when you caught Dong Sik.
You got a special promotion, and you were the people's hero.
This conglomerate heir even asked you out.
Why didn't you say yes?
That was generous compensation, don't you think?
- Do you think that matters? - Then what does matter?
The truth? Your conscience?
You're just as lame as Dong Sik.
I guess we can get started now.
This is my father's gun.
I expected this would happen, so I said Dong Sik took off with it.
It's hard just to survive in these times.
But if you want to succeed...
It's insanely hard.
But if you're controlled by lame emotions on top of that,
you're perfect bait for people like me.
Darn it.
(Ms. Jo Yu Jin)
What? The cops?
Hold them off.
What's going on?
What happened here?
My gosh. Mr. Seo Jin Hoon.
My gosh. Are you okay?
Why are you bleeding so much?
- This isn't my blood. - What?
Let go.
Where's Seo In Woo?
Seo In Woo, you dirtbag.
You're dead now.
Darn it. Dong Sik, you jerk.
It's over now.
Give up.
Seo In Woo!
(Psychopath Diary)
Mr. Yook, it's all over now.
- A gunshot? - That was a gunshot.
My goodness. Come on. Hurry.
Drop your gun, Seo In Woo.
The shocking truth regarding the predator killer...
that shocked the entire nation has been revealed.
I bet he's locked up in the worst type of prison.
How does it feel to have your name cleared?
I'm nothing but a dimwit.
Our main event has only just begun.
