[Previously]
Send me to the jail clinic.
You're tough.
I'll fall for your trap, and let's gamble.
With hunting…
…chasing the prey is half the fun.
Cruel prick.
Mad Monk would beat you to a pulp.
Ryu Tae Oh was recently released from the jail clinic…
Maria's whistle.
There' s an alibi. He's not Gap Dong.
Bye.
Hold on… Who gave that alibi?
Doctor Oh Maria.
You rat.
You were the Gap Dong out here?
[Episode 6]
I came back with an urgent question.
For my jail clinic senior.
Gap Dong…
They already did an investigation. I had an alibi too.
Come on.
You're acting like you're guilty.
Would I possibly think you're Gap Dong?
I just wanted to ask...
...if there were any rumors among the prisoners.
Regarding who's Gap Dong.
Well…
There were tons of groundless rumors.
But we can't know who's the real one.
Then do you have...
- …anyone in mind? - Anyone I have in mind?
To be honest…
…I think it's you.
No offence. I'm sorry.
Don't apologize.
My colleague detectives think it's me too after all.
Even detectives can't find him.
How could I?
It's not like we're both psychopaths.
Both psychopaths?
Insane dudes can spot insane dudes.
Why don't you get going?
Sure.
Come on.
We're just getting started now.
Insane dudes can spot insane dudes.
Why didn't I think of that?
I could've sent imprisoned Yu and Jung to the jail clinic...
...to catch Gap Dong.
You should go too, Mr. Ha.
Or…
…why don't we take a fun test while we're on the subject?
[Incompetent Cops Mistake Co-worker Detective as Gap Dong]
You can't catch one crazy guy?
What's with the chaos?
We didn't increase the security budget for this.
I'm ashamed.
I'm saying we could lose the people's support.
Sir…
We have no choice...
...but to rely on the detectives' hunches?
I heard they're developing a weird device...
...to measure a psychopath coefficient.
We use the Robert D. Hare's Psychopathy Checklist too.
Korea has developed KCP PPIR too.
Psychopath test?
He just said…
…insane dudes can spot insane dudes.
PCLR?
I turned out normal.
Even Ted Bundy got a 27.
I mean tests for fun.
- I was going through profiling data… - Sounds fun.
It's even thrilling since it's with a detective.
Shall we start?
Two sisters went to their grandma's funeral.
They met their distant relative there.
But he was...
...the sisters' perfect ideal man.
They were agonizing over their simultaneous find.
- So? - Something scary happened...
...the next day.
The big sister killed the little one.
Why did she kill her?
Ok… Answer me, you two.
Jealousy?
That's what people normally think.
Of course that's not what this test expects you to answer.
What about you?
Gosh…
I think I know.
Should I tell you?
No suspects?
So that you had to imprison a member of the police family?
This case has become too big...
...for just the Iltan Police Station can handle.
We'll get help from the Gyeonggi Provincial office.
Who will be...
...the head of investigation?
The Chief of Gyeonggi Criminial Investigation, of course.
A veteran regarding Gap Dong...
...will be better.
[Iltan Serial Murder Joint Investigation Headquarters]
I'm the chief of investigation, Yang Cheol Gon.
Thank you for coming to help us.
I'll do my best to catch him.
Let's find out...
...our Gap Dong and the old Gap Dong's...
...secret too.
[Ryu Tae Oh]
He didn’t mention his dad to you either?
Mentioning trauma is important for treatment...
...but he didn't.
I see.
I'll talk about something special during today's session.
Special?
- What color does this look like? - Gray, no?
What else could it be?
Psychopaths think it's red.
- It even moves. - Really?
Ha should take the test.
Why you…
What?
Oh, who do we have here?
Are you back to work?
No word to come back yet.
We need a hand here.
We almost lost Mr. Yang's hand…
…because of him.
Why you…
I have a favor to ask.
What is it?
[Background Check]
Do you know the Chairman Ryu murder case?
He's the son.
[Ryu Won Jun murdered No prime suspects]
He witnessed his parent's death…
…and became a drug addict due to the trauma.
It's a typical course.
There were no prime suspects, eh?
That's why the case became famous.
This was unsolved too.
I was thinking…
This kid wasn't investigated.
What do you mean?
Maybe...
...this kid, Ryu Tae Oh…
I never told this to anyone.
I think I could…
…tell you.
Because I trust you.
What a long foreshadow. It must be a special story.
Can you promise me…
…you'll be there for me to the end?
What do you mean, be there for you?
The beginning and...
...end of my misfortune.
[12 years ago]
What are you talking about?
He's a monster...
...and we can't handle him.
He's our child. We can't report him.
You saw him...
...throw his brother like a rag doll.
Let's die together.
Let's all die together, honey!
My dad thought...
...I was a special kid.
His interest in me was hard to deal with.
Honey, this is wrong.
Honey! Get up!
Honey!
Tae Oh…
You...
Did you…
I…
…don't want to die, mom.
Ma'am.
Are you okay?
Ma'am.
Take her.
The criminal…
…still hasn't been caught.
That's making me go nuts.
Don't.
What if...
...that was Tae Oh's first murder?
I was just a cop and couldn't investigate.
The records say he didn't really resist.
Don't you think it's weird?
Who killed my dad?
I said, "who killed him?"
Gap Dong?
Who's that?
That's when it started.
Your hell.
Yes.
The world started to look different.
I wasn't interested when my friends went crazy...
...over the World Cup.
Even Gundam robots I used to love.
How old were you then?
I was...
...only 12.
I've wanted to meet my hero since then...
Gap Dong.
What if he's a psychopath?
You have some evidence?
Why would I be here if I did?
But something's weird.
He's starting to smell like Gap Dong.
Why would he do that to a detective...
...unless he's dying to get caught?
What if...
- ...I'm his Gundam robot? - You mean the toy?
Yes.
There was a dumb cop at his first murder scene.
It was fun to play around with him.
And he became a violent crime detective.
He still wants to…
…continue playing with me.
It's all hypothesizing.
Since detectives should be able to.
I've heard that line before.
Well, sir.
Why don't we research this guy?
He's sending me weird signals.
"Catch me if you can."
You know what worries me the most?
He keeps lurking around Oh Maria.
What?
Lurking around Maria?
I can't do it.
Because of my son...
...Seong Uk.
You'll have to do it because of him.
Or...
…he'll die.
The 4th case was...
...the most controversial among...
...the 9 Iltan serial rape/murder cases.
[20 years ago, the day of the 4th crime]
The victim was Kim Yeo Jeong, who just got married a month ago.
Sorry, I have to go.
It's late, just go tomorrow.
I can only see him on the weekends.
Newlywed life must be good.
You're gonna run into Gap Dong.
Stop it, it's scary.
I have this.
I better go. Bye.
She stayed at her factory dorm...
...and went to visit her husband every weekend.
She was walking to Iltan Station.
She was attacked...
...and found under the waterway the next day.
Her wedding picture, makeup, purse...
...safety whistle were found.
Her hands were tied with her underwear.
So the MO was found to be identical.
But the issue is this milk carton.
Gap Dong's blood type was assumed...
...to be type B in the 3rd case.
The saliva on the carton showed...
...type AB.
So it's still controversial...
...if Gap Dong 4 was the same...
...as 1, 2 and 3.
Mad Monk?
You scared me.
Get off me.
No.
You were released ages ago. You show up now?
I texted you over 100 times. No reply.
How'd you get in here?
Get out.
No!
Geez.
Wait.
Did you block me?
No!
Do you live here?
Yeah, I did. To see Mad Monk.
[Dr. Oh Maria]
What's between the two of you?
You having an affair?
Affair my foot.
She kept comforting me with ramen.
I'll just…
I came for an interview.
- Interview? - Didn't I tell you...
...I'm working on a famous webtoon now?
I wanted to see what a jail clinic was like.
This is what connections are for.
Take me in.
Sorry, I can't.
You don’t want to help, eh?
You're too young.
- You want to treat me like a kid, eh? - And you're too pretty.
So are you…
That's cute.
Where'd you buy that?
Did someone give it to you?
Did…
…my Mad Monk give it to you?
- I can't take you in, but I can… - Forget it.
That's nothing.
I...
...got this, this...
...this...
...and this from him.
That's not all. He helps me with Monster's Path.
Don't play hard-to-get.
I can get Mad Monk's help.
- Monster's Path? - Don't you know?
They're saying it's the same as Gap Dong's case.
Can you show me?
Why'd you take me in? I'm useless.
You should've left me...
...when my dad died. Then you wouldn't see this crap.
Mu Yeom.
We're short on rice.
When will they let you work again?
What happened to the paycheck I gave you?
There are many people here.
Don’t try to get credit for peanuts.
You should save...
...and invest like others.
Geez.
[Dr. Oh Maria]
I was bored. No one was calling me.
I'm so grateful.
Why don't you buy me dinner while you're at it.
Oh, your boyfriend might not like it.
Boyfriend?
Aren't you dating Ryu Tae Oh?
Why would you think so?
I saw his records.
You were with him during the 1st and 3rd cases.
I'd consider that dating.
Will you be with him for the 4th case too?
I wanted to ask you a question too.
I heard you coached Ma Ji Ul's webtoon...
...Monster's Path, down to the details.
Is that true?
I looked into it.
The webtoon goes ahead of the case.
What are you talking about?
What path?
Why this…
She said I told her all this?
Nice moist eyes.
Perfect.
You called to see me for a change.
You're not sick, are you?
What would you like?
Their cheese cake and...
...croissants are good…
You have a conscience?
What's with you? Just tell me if you like me.
- What's with this? - What?
I told you all this?
She went telling on me already?
She was bragging…
How'd you know the victim was a hair stylist?
It was...
...just a coincidence.
It was uploaded after the crime, but I wrote it way before.
Then it makes even less sense.
- Are you the criminal? - Huh?
Your webtoon is a murder preview? You're a fortuneteller?
How does it all happen like that?
Actually…
Who is it?
Which detective told you? Mr. Nam? Lee?
Tell me now.
- I'll just… - A guy I know...
...gave me the idea.
Who?
It's not his shift yet.
He's here. Him.
Are you interested in Gap Dong?
Or do you know who Gap Dong is?
What now?
Oh, the test?
I just said I knew because I thought I knew the answer.
You gave her ideas?
What? You go to jail for giving ideas?
It depends on the idea.
But how'd you know?
- Know what? - Hair stylist.
It's simple.
The old case. Anyone can imagine it.
DNA…
Hair… Hair stylist.
- It's all imagination? - What else?
What else could it be?
You think I could be Gap Dong.
Yes, Ryu Tae Oh.
Are you Gap Dong?
Ha Mu Yeom.
You've finally recognized me.
What did you want to tell me urgently?
I wanted to congratulate you on becoming chief...
...and work your finger's worth.
I thought you had run away.
You're the best with catching Gap Dong.
But I didn't find him…
The guy came to me.
Came to you?
Lawyer Kwon, it's me.
What is it?
What did you discuss with him?
Don't meet him from now on.
Was he...
...really a psychopath?
- Hello? - It's the rat.
Do you have time now?
Depends on what it's about.
- I think it's time I tell you the answer. - Answer?
Didn't you want to know my answer?
About the sisters that met their ideal guy at the funeral.
The reason why she killed her sister…
But…
…will I be arrested as Gap Dong if I get the answer right?
If everyone were thrown into jail for answering quizzes…
…no one would play Jeopardy.
You really want to know?
It will be hard on you.
The weather is making my wound ache.
- Stop annoying me… - They met the guy at a funeral.
Maybe to see that guy again?
She needed another funeral to see that guy again.
No?
Why you…
Who are you?
He just admitted himself that...
...he's a psychopath.
It's so weird how he came to give the answer.
Dude looks like a pretty boy.
Cha, have you seen a psychopath before?
- Yes. - You have?
You forgot the murder factory case?
That was no psychopath.
Wasn't it just group madness?
I'll ask you one more thing while you're here.
No more tests, please.
If I get it again, you'll be really suspicious of me.
What's your reason for acting this way?
Why are you revealing your identity?
I don't know.
The net's answer isn't correct.
According to the FBI...
...psychopaths surprisingly answer…
…sisters' jealousy.
- Really? - There was no psycho...
...who answered like you.
Yeah.
They wouldn't distinguish psychopaths with a simple question.
You just happened...
...to guess the answer.
You could've read it somewhere. But…
…why are you proving what kind of guy you are?
You should find out yourself.
- Me? - Yes.
It's your turn to tell me.
Why I'm doing this.
[Hide well. Oh Maria!]
I said I'm not selling it.
Can I borrow it then?
I'm jobless now. I want to take a tour.
Go home.
You can have homecooked meals.
What's with you?
I'm being kicked out of the temple too.
I'm so unlucky. Everyone wants to kick me out.
Ryu Tae Oh.
Is he Gap Dong?
You're scary.
You kept meeting him, knowing that?
I needed confirmation.
That he was Gap Dong.
Arrest?
Arrest and what?
We could arrest him for 48 hours...
...until the forewarned 4th crime date.
And then?
We'd have to release him due to insuffient alibi and evidence.
We should look for proof after we catch him.
You know if we release him like that...
...we can't catch him again without concrete evidence.
Sir, I found Ryu Tae Oh's texts as you'd ordered.
I'm wondering if she's the 4th target.
- Target? - Yes, she's…
…the jail clinic's Dr. Oh Maria.
Gosh, Jodie Foster would laugh.
You're acting like her in Silence of the Lambs.
You're brave, strong, smart, and sexy too.
Come on, it's not a compliment.
How could you laugh?
This is reality.
A psychopath is lurking around you.
Then...
...should I run away?
Would he...
...give up if I run away?
Of course you should run away.
You're not a cat with 9 lives.
Don't try to copy Jodie Foster. You could die young.
Don’t even make eye contact...
...with Tae Oh with those big eyes.
Let another doctor treat him.
Or take a sick leave.
Why aren't you answering me?
You understand?
[Hide well. Oh Maria!]
What is this?
It's not...
- ...you, is it? - Huh?
How could you think…
You're...
...the same.
Just like everyone else.
- Disappointed? - Yes.
Very, to be honest.
I thought…
…you'd be on my side.
I wish...
...it weren't you too.
I'd like to be assured.
Then…
…will you be with me that day?
- That day? - Tomorrow's the forewarned 4th crime day.
I'll show you the world was wrong.
They're mistaken.
You're suspicious of me.
Ok.
Good.
I'll see you tomorrow.
I can't do it.
Mommy...
You'll die if you don't.
Again.
Rock, scissors, paper.
Rock, scissors, paper!
This time...
Not this time. Never.
So she'll do it?
She has crazy guts.
I've done gutsy investigations but...
...I've never seen this happen.
She's not even a cop. What if something happens…
I won't let anything happen. I'll kill him before that.
What are you thinking?
Don’t think you could protect others.
It hurts most when detectives…
…can't protect loved ones.
You can't even protect loved ones?
If that happens, I'll resign as a cop.
Let's see.
Who does Oh Maria think she is? Brave Joan of Arc?
It's Dr. Han's influence.
Dr. Han?
He got married in Australia.
Dr. Maria is his wife's daughter.
Scared, eh?
You're regretting it.
You wanna take it back.
No one would accuse you for refusing now.
It's not cowardly to run away.
I don't want to run away.
Why are you acting like you're cool?
You said I'm like Jodie Foster.
I'm unlucky alright.
I met a girl who won't listen to me. Just my luck!
Who knows?
You could catch Gap Dong and come back to work, thanks to me.
If you're not going to run away…
If you're not going to run away...
...don’t lose sight of me.
If you're not going to run away...
...don't let me lose sight of you.
Gosh.
I feel so worried about you.
I'm no babysitter.
How could I have peace of mind?
No way!
Why not?
What if Maria's falling into the trap?
And what about Ha?
- He's in a corner here. - Is that why?
You're just worried about him?
I think this is just too risky!
Did you learn about the Gap Dong case...
...from books, you smart aleck?
I participated in the investigation when you were demoted.
Mu Yeom almost died by nunchucks.
- That was you? - Don't think...
...only you know Gap Dong.
I'll choose what's best.
I know Gap Dong!
I'm the boss here!
Did you learn about the Gap Dong case...
...from books, you smart aleck?
Get up.
The elixir of life wouldn’t even help.
I don't think I'll live past 50.
What now?
What did you do this time? Cops are outside.
You're still chasing that crazy detective, eh?
Just leave home if you wanna be like this.
Get out, get out!
You think I won't?
You have no where to go.
I'll really leave.
But you know what today is, eh?
I'm leaving.
Bye.
- Bye. - Bye!
- Hello. Bye. - Bye.
Dad!
My boy…
Bye.
Dad. Earlier today...
- I scored two goals in soccer. - Yeah?
That's cool.
Did you eat your snack?
Good job.
I want to punch that pretty face of his.
Aren't you being jealous of his looks?
Hey, you call that a guy's face?
Scary Tiger and I have a man's face.
You don’t have a mirror?
Why you…
God is thoughtless...
...to give crazy dudes like that prick...
...and Ha good looks.
Don't mention him.
Shut up.
Don't talk to me that way.
What? We can't see him.
Go follow him.
Are you ok?
- I'm sorry. - Are you hurt?
I'm ok.
Over there.
[Ryu Tae Oh]
Hi, Tae Oh.
Ok, I'll see you there.
[Forewarned 4th crime date]
How is it?
Focus.
- Focus on this area. - Yes, sir.
Hello?
Having fun?
Yeah.
You're really brave.
- What? - You know.
I could be Gap Dong after all.
You said you'd give me conviction that you're not.
At least one person believes me.
Dr…
Ryu Tae Oh.
Ryu Tae Oh, answer me!
Hello.
What?
Excuse me…
The 4th case just occurred.
I was duped.
By your plan, Ryu Tae Oh.
Yeah, Ha Mu Yeom.
I knew you'd take the bait.
This way…
The 4th serial murder occurred...
...on the forewarned day as expected.
[4th Serial Murder Occured]
Cho, the alleged Gap Dong...
...was an elem. school clerk in his 40s.
The moment Mad Monk bites the bait...
...I'll become the suspect.
And...
...I'll be completely acquitted.
That's...
...the core of the 4th case.
He was living...
...with his 8-year old son on welfare.
It's shocking that the victim...
[4th Serial Murder Occured]
...worked in the same school.
Hey! Be quiet.
Turn it up.
[Prime Suspect hit by a train]
...investigating the relationship between victim and suspect…
That monster!
...to figure out the motive…
They're also trying to find out...
...the connection to cases 1-3.
Was Cho really Gap Dong...
...who committed the Iltan serial murders?
The investigation results will tell.
Mad Monk will prove it himself…
…my innocence.
You'll see.
How Mad Monk will prove my innocence.
You know?
The more a fish...
...that bites the bait moves...
The more it moves like crazy...
...the sooner it'll get exhausted.
And the fisherman will get excited.
That's...
...the beauty of fishing.
Dad, dad! Dad!
Could I get…
What are you going to do?
You'll really shoot me?
You like this.
Gambling with people's lives.
6:1 is a good ratio.
Tell me! Who's the Gap Dong inside?
You wanted to do this…
Five left.
Who's Gap Dong?
Tell me!
If you kill me, you'll never find out…
Your luck is running out.
Only two left now.
You should say...
...goodbye now.
Farewell.
- Gap Dong. - Wait.
He played Russian roulette with an innocent citizen.
Detective Ha Mu Yeom.
Complaint filed.
Even killers have rights…
Mu Yeom…
Nah…
I don't know the relationship between you and Mu Yeom…
Did something happen to him?
I'm not normal anymore.
No emotions and I can't control my impulses.
[Gap Dong]
