Han Byul.
Han Byul?
Han Byul!
Dad.
There are signs of perception symptoms, and you're experiencing...
an incident that has already happened again.
You're going to feel the pain...
you felt because of the incident.
It can be dangerous.
Seeing and hearing things are its presymptoms.
If you don't get rid of it quickly, you'll experience difficulties.
If you don't get rid of your obsession,
it will cause only more problems.
I still have things I need to do.
Yes.
I understand.

What was the first case in which profiling came into spotlight?
The Mad Bomber Case in America.
What is this? Is this a quiz?
Psychiatrist James Brussel was in charge of the profiling.
He even knew that the culprit...
would wear a two-button suit,
and have it all buttoned up. He had profiled him in detail.
And when the culprit was arrested, he looked just like the description.
On the other hand, some believed...
that it was just one of the police's composite sketches.
When you are investigating a case, you can't get an answer...
straight away by simply solving an algorithm.
One more question.
Who is the serial killer...
who said he could quit smoking but not killing?
- That was... - Yoo Young Chul?
Jung Dang Gyu.
He could not withhold the desire to kill...
and killed himself in prison.
In Dante's "Inferno",
he classifies the evil features of humanity into seven levels.
"Inferno" was written in 1310,
so that was when the term profiling...
Of course, it's Doctor Lee's lecture on the world learned from books.
Today's topic must be literature.
It finally feels like we have you back.

Excuse me.
You left your notebook.
Excuse me.
You left your notebook. This is quality information.
The phone is turned off. Please leave a message after the tone.
Her phone must be out of battery.
Although I am looking at you, I miss you
Although I am looking at you...
Is my princess home?
The princess is not home yet.
Did you call her?
She could get stressed out. I shouldn't call her.
- Although I am looking at you... - It will be getting dark soon.
Although I am looking at you, I miss you
- Honey. - Yes?
What is this?
I think Eun Jung sent us that.
You should see what it is.
- Honey. - Yes?
You should come and watch with me.
All right.
- I am so sorry. - Honey.
- What is it? - I am so sorry.
What's this noise?
I am so sorry. I am so sorry.
I am so sorry.
Team Manager Kang, are you all right?
Yes, I'm fine. Continue.
We do not know if the kidnapped victim has been murdered yet.
The police station in charge has asked us for consultation.
Call in the team members.
Did he really send this to her family?
When did the victim go missing?
The police think that it was 3 to 5 days ago.
Why is the time of abduction not exact?
Victim Jo lived in a study room...
and used to turn her cell phone off for 2 or 3 days for her study.
That means her parents didn't know that her daughter's gone missing.
It's not clear when she was abducted.
There's no suspect.
There's a very low chance...
that it is for money or revenge.
Wait.
It's not clear because of the loud music,
but I think the man is saying something.
The music was not added in. It's from the site.
It will take a while to separate his voice.
Wait. What's that on...
the masked man's wrist?
Give me a second.
That looks like some kind of a pattern.
It could be a trace.
Are you telling me to find out what this is before analyzing the voice?
Fine.
We might get a suspect if we compare it to people around her.
Generally, sadistic criminals tend to be...
someone the victim doesn't know.
It is easier for the criminals to torture and kill...
the person they don't know.
Filming a criminal action is...
a basic sign of sadistic fetishism.
Even though there's a danger of exposing their identity,
they still film it and send it to other people.
It comes from a strong desire of domination.
They feel pleasure...
from the suppression and from watching the victim suffer.
By showing how cruel they are,
they make the victim fear,
and it also shows their desire to be recognized.
The important thing here is not why,
but to whom the video is sent.
Since 2015, there were these three murder cases...
that took place in Seoul and Gyeonggi Province.
These three unsolved cases...
have something in common.
What's wrong?
My baby. What happened to my baby?
The first person to find the body was the parent.
The criminal abandoned the dead body...
as if he knew the path of their parents.
But this time, he sent a video instead of a body.
He's pursuing pleasure.
He's trying to make it even more painful.
It will be worse for parents to face their children suffer...
than to see their dead bodies.
Right. The criminal has evolved extremely...
through three murders.
The bodies were found a week after the victims went missing...
in all the previous cases.
Going by the patterns, we have about three days left,
but this time, they sent a video.
Sending a video means...
they're not interested in the victims anymore.
Team Manager Kang. Jo Eun Jung's body was found.
There are lacerated wounds in the neck, chest, and thighs.
She's also missing a few fingernails and toenails.
By looking at the purple spot,
the torture went on for a few days.
The place where he abandoned the dead body is so different.
Until now, the bodies were found...
in a place where their parents would find them first,
but this time, it was abandoned in a place where no one would find it.
If the criminal's goal was to conceal,
he wouldn't choose a place like that when there are...
better places to hide it.
Why...
did he carry the heavy body...
and come all the way down here?
There must be a reason he changed the pattern...
like a change of mind.
No. We probably missed something.
Unless he was aiming for something,
he wouldn't have abandoned the body here.
What if there's a private place...
hidden from hundreds of climbers?
Team Manager Kang. Right here.
A symbolical place where it would...
maximize the pain of the victim and her parents.
There's a reason why the criminal chose this place for abandonment.
Eun Jung. It's Mom.
It's Mom. Get up. Let's go home.
This is Boksil.
She's Eun Jung's sister.
Her father bought her because he was worried she might be lonely.
Eun Jung loved her so much.
You made a grave for the puppy?
Yes.
It's where we go every time we want to rest.
Eun Jung said...
we should bury her here.
Are you...
wearing the same ring as your daughter?
Didn't you see it?
Didn't you see it when you found her?
We got this ring...
on Eun Jung's 20th birthday.
The location of abandonment doesn't have anything to do with her father.
The name written on the CD was Eun Jung's mother.
(Namcheon, Eunsung-gu, 421-24 Gusung-dong, Lim Joo Sun)
Lim Joo Sun.
The receiver's name itself was the message.
All the first finders of three previous cases were...
also their mothers.
The criminal's target was...
not the family but their mothers.
Why are you watching this cruel video?
- Stop. - What?
Stop. Stop. Stop. Stop.
Right here.
The man in this video isn't doing this for himself.
He's aware of the audience.
Right there. It's moving.
It's not fixed.
That was because she bumped into it.
Look. He's looking back.
It's the third time.
As you can see, the criminal is aware of someone.
Team Manager Kang. Here's the DNA test result.
It's weird.
The previous DNA...
and Eun Jung's DNA don't match.
Because there's more than one criminal.
Pardon?
One is torturing,
and the other is filming it.
It's folie a deux, shared psychosis.
It's a psychological phenomenon of sharing a same mental delusion.
It's like a fellowship to bring out...
the cruellest part in them.
The dominant criminal...
forces the other relatively weaker accomplice to murder...
and uses it to threaten him.
That's how the dominated person opens his eyes to a murder.
I told you we've already looked at it.
No. There must be something.
Stop.
Play.
Wait.
See? I told you she wasn't abducted here.
She just walked out.
You should come outside with me.
Sun Woo, you should keep watching the footage.
This is the reason why there was a shadow in the corner.
If you move in the blind spots, it's possible...
to move without being seen.
The culprit lured the victim without being seen on the security footage.
But why did Jo Eun Jung follow the culprit?
Rewind the tape please.
She's holding a notebook.
But why did she hesitate?
What if it wasn't from her bag?
Rewind the tape please.
Excuse me.
Wait, Sun Woo. It's me.
One person lured the victim, and the other kidnapped her.
The accomplice must have been hiding here.
It's an obscure and secluded place.
The two culprits kidnapped the victims,
while using the blind spots to move unseen.
This is how the culprit...
lured Jo Eun Jung.
A kind heart to help others.
Mother, how did the examination go?
I'm sorry.
You couldn't study even though it's your exam period.
Did anything happen at the store?
Were there many customers?
Of course you would say that.
Nothing matters more than selling more.
You must be feeling all right now.
Aren't you hungry?
Do you want me to cook something?
It's all right. I'll buy ramyeon on the way.
I'm nearly home. Just boil water for me.
Do you need help?
Are you going up there?
Do you think it was the same culprit?
If you look at the victim's age, appearance,
and the way in which she went missing,
it seems likely.
The police station wants to start an open investigation.
They shouldn't.
The culprit didn't send any videos yet.
That could indicate that the victim is alive.
Once the police intervene,
this won't be fun for the culprits any more.
If they can't get fun out of the victims,
they won't need them alive.
We need to analyze their behavioral patterns and jobs...
to narrow down the suspects.
Let's start profiling the culprits.
Seeing as the victims followed them easily,
they must be good looking.
And as the victims are in their early 20s,
the culprits will be either in their 20s or 30s.
They abducted the victims freely...
between morning to night on weekdays.
They disposed of the bodies...
during night or dawn.
Considering the time of the crime and the disposal of dead bodies,
it seems likely that they don't have jobs.
If they do,
the jobs won't be time constrained.
As sadists,
they would be unsociable.
One of the accomplices...
would be the leader, controlling the other skillfully.
Seeing as they torture the victims,
it seems likely...
that they were abused by their parents.
Mental stress that they receive from such experiences...
sometimes cause damage in certain parts of the brain.
Some sadists...
who are violent and dominant...
try to get over the feeling of helplessness...
by using violence, committing arson, or killing violently. In the end,
they're continuing the vicious cycle of using violence.
One peculiar thing is that they considered the close relationship...
of the victim and her mother as an important factor.
They didn't pick random victims.
They have information on them,
and based on the information,
they know about the parents' behavioral patterns as well.
I'm sorry, but you need to watch something.
If you have my daughter, Kwon Yoo Jin,
please, please, don't kill her.
She is everything to me.
Please let Yoo Jin...
come home safely.
The police consider the abduction of Kwon Yoo Jin two days ago...
as a part of the Namcheon Serial Abduction...
and Murder Case that has continued for the last two years.
Call the media to stop broadcasting more about this case.
Yes, sir.
The police needs to investigate quickly...
so that there would be no more victims.
Please don't kill me.
Next,
the police are investigating the recent abduction cases...
while considering the possibility that it is a serial killing case.
However, according to the persons concerned,
there is no evidence yet that can prove the possibility.
Where are you going?
Do you really think that they won't be able to find you?
Nana, did you stay up all night?
I think I've seen this...
gruesome mask for over 3560 times since last night.
I've been engraving this image of a poor girl being tortured by...
a masked mad man into my brain.
I've been...
watching this for 22 hours.
Why are they placed like this?
No, don't touch it!
My baby, you shouldn't see horrible things like this.
You should stay like this for a while and wait.
Oh, my.
I got it.
It wasn't a special tattoo.
It's a common tattoo that young men prefer nowadays.
We can't narrow down the suspects with this.
I've seen this four years ago.
Four years ago? Where?
In 2003, a famous celebrity committed suicide after...
his pornography videos had spread.
For eight months, there was a big investigation on pornography sites.
I think I've seen that on one of the files.
You should bring them. Let's check them together.
The files have 67,321 pages.
It could be too hard to check.
67 thousand?
Even if we had dozens of people, we won't be able to check all that.
Should we analyse the audio first?
(Case Files)
I can do it by myself.
You should thank me.
Let me do this.
I feel like I need to do something.
(Kwon Yoo Jin)
Don't open anything...
from your daughter...
and call us first.
(Video File)
(Kim Jung Sook)
Ms. Kim, are you all right?
I heard everything...
from the reporters.
I know what that is.
Did you watch it?
I couldn't bear to watch it.
That was a good choice.
Yoo Jin...
wanted to go to...
her friend's house to study.
But I told her to manage the store.
I had an examination for my thyroid.
It was because of me.
It wasn't. Don't say that.
Every time my husband saw Yoo Jin,
he told her to be sly.
He said the world is too dangerous to trust anyone.
But...
I told her that's not true.
I told her to be kind, honest,
and to help other people.
That's how we should live our lives.
I didn't expect this to happen.
I shouldn't have said that.
Ms. Kwon.
Don't worry. We'll find...
Kwon Yoo Jin for sure.
I beg you.
(Pornographic Site Report)
Stop.
Magnify this table please.
It's the same table.
That wall.
There was a picture on that wall.
If you consider the distance from the window,
the location of the nail and the picture match.
It means it's the same place.
The S written on his wrist...
meant S Culture.
S Culture?
They made a fake sadistic video...
on a secretly operated internet show.
It disappeared four years ago during the investigation on pornography.
There's no exact information because they used overseas server.
No way.
What?
Give me a second. I'll be right back.
Here. Enjoy.
Red... Red House?
Wolf and Asia.
What are you doing here?
Do you remember it? It was when we were the best.
Put it away. I don't want to see it.
I'm busy. Just answer my questions.
If anyone finds out I'm handing this over,
it will affect my business.
I sent it.
Goodbye.
Red House.
I don't think you betrayed us.
His name is Kang Jae Deok. He runs S Culture.
He's 31 years old. He has a record of several imprisonments for rape,
assault, and distribution of pornography.
His address is 6 Hahwae Street, Namcheon.
He works at Sung Un Trading. It's registered as a trading firm.
Kang has records of...
going under investigations for domestic violence when he was young.
The record says his mother ran away long time ago.
There's also records of him hurting himself in the prison.
His sadistic tendency grew...
as he was exposed to a long period of violence.
Who are you?
Are you okay?
Who is it?
I'm here to see Kang Jae Deok.
I'm Kim Hyun Jun from Special Crimes Investigations.
I'm here to investigate on recent murder cases.
Go away. He's not here.
Please cooperate with the investigation.
Why would the police come to my house?
There's nothing to investigate.
Is there someone inside?
Go away!
Kang Jae Deok.
Don't do anything stupid. Okay?
I'm not going to the prison.
I'm not going there again.
Never.
No. Stop.
Calm down. Calm down.
Get down here and let's talk.
Kang Jae Deok.
Okay.
Your son jumped off...
the roof while he was running away.
Did he die?
You look sad.
Are you serious?
How would you feel if you son dies?
I understand you're sad,
but your son is a strong suspect...
of 4 murders and 1 abduction.
That jerk is dead now.
Get out of my house now.
I have to save the currently abducted victim.
Is there anything you know by chance?
Disorder.
This dirty room is far away from...
the sadistic tendency where he controls someone.
No mirror means...
he rejects himself.
Showing a desire to control someone...
means he's controlled by someone.
He's a subordinate who feels comfortable being dominated.
It looks like the second victim, Choi Eun Seo's fingernail.
He kept a souvenir...
to commemorate his murder.
There's nothing else found here.
Kang Jae Deok? I know him.
We broadcast together a few times.
What? You saw it's all a lie.
Anyone who film this for real would be a psychopath.
Do you know anyone in here?
If I tell you, will you set me free?
Look closely.
This guy.
He worked together with Kang Jae Deok at S Culture,
and he has the same tattoo on his wrist.
Yoon Jeong Sub. He's same age as Kang.
He grew up in a child-care institutions since he was 8.
The address is...
Who are you?
Please excuse us. We're from the NCI.
We're here for Yoon Jeong Sub.
What's your relation to him?
Please come in.
- He's not picking up. - The person you are trying to...
reach is unavailable.
You decorated the house nicely.
It's very organized too.
My husband is very neat.
Has anything out of the ordinary happened to Yoon Jeong Sub recently?
Anything out of the ordinary?
No, nothing comes to mind.
Where is your husband right now?
I'm not sure.
Do you happen to know a man named Kang Jae Deok?
Yes, I do. He's my husband's friend.
But could you stop asking questions,
and explain to me why you're asking?
Kang Jae Deok is dead.
Kang Jae Deok was a strong suspect for a serial murder case.
He died from an accident while on the run.
But why are you looking for my husband?
We have nothing to do with Jae Deok.
Aren't you hot?
No.
Your husband...
must like to drink.
No, I drank those.
But...
why did you come to find my husband?
We were only questioning his acquaintances out of formality.
If you happen to think of anything,
please call this number.
We'll be on our way.
The house is tidy and organized.
There are mirrors hanging everywhere.
I see traces of a sadist all around,
trying to control all corners of the house.
Did you see Song Yoo Kyung button up her shirt,
and pull down her sleeves?
Yes.
It must be to hide...
bruises from being beaten by Yoon Jeong Sub.
She's been trained to be helpless.
Do you think it's a type of Stockholm syndrome?
It is.
Song Yoo Kyung believes that...
if Yoon Jeong Sub is taken away, she will have no one to rely on.
It's difficult to look forward to her cooperation.
I'll go in hiding...
until Yoon Jeong Sub returns.
Song Yoo Kyung.
Song Yoo Kyung!
Search around the house now. Hurry.
Yes, sir.
Sir, Song Yoo Kyung...
has escaped.
We have to find her.
I'm sure she went to him.
This is the last time we see her.
Her phone is turned off.
If Yoon Jeong Sub finds out that the police visited,
he might resort to extreme measures.
Kwon Yoo Jin will be in danger.
Please don't kill me.
Team Manager Kang, some woman is here to see you.
Ms. Song,
what happened?
I was nervous,
so I went looking for him.
What did you tell your husband?
I told him the truth.
The police came and asked about a murder case.
I told him everything.
Did he beat you?
I don't know why he suddenly did this to me.
Ms. Song.
If you are hiding anything, please tell me the truth.
To be honest, I...
I can't drink.
Your husband must like to drink.
No, I drank those.
Usually, he's kind and good.
But once he starts drinking...
You pathetic woman...
I'm sorry.
I'm sorry. It's all my fault.
He'd only do it when he's really drunk.
I'm sorry I lied.
I was scared and I didn't know what to say.
I just...
didn't want to betray him.
I love him.
That ring...
Did your husband give it to you?
Yes.
It was a birthday gift.
Why?
Your birthday was a couple days ago.
Yes.
But how did you know?
That ring...
Did you get matching ones with your daughter?
It was for Eun Jung's 20th birthday.
We got matching ones.
It seems to be the victim's ring.
I went to find my husband.
Whenever he'd play cards, I couldn't reach him for days.
We met in front of a bar.
And he started beating me out of the blue.
I don't know where he went afterwards.
- Status? - It's the second floor over there.
Let's go up.
Raise.
- Everyone, stop what you're doing. - Yoon Jeong Sub.
Stay put!
- What is this? - Don't move.
Follow me.
You don't need to watch.
Would you like a cup of tea?
He doesn't look nervous at all.
He won't open up his mouth easily.
He's a dominator type.
They prepare and practice every single tiny thing,
just in case something like this happens.
(Kim Hae Jin, Choi Eun Seo, Lee Ji Soo, Jo Eun Jung, Kwon Yoo Jin)
Turn off the AC in the interrogation room.
And dim the lights.
It's a form of psychological interrogation.
People also call it psychological torture.
Bright lights and complete darkness.
The humidity and temperature keep changing,
making the suspect nervous.
We have to create an environment that's drastically different...
from the one he predicted and simulated.
Are you not going in?
Wait, he's responding.
If we want to find out where Kwon Yoo Jin is,
we have to make him slip up.
I'll go in. I'll try provoking him.
How do you feel?
DNA was found on the body.
It's being proceeded right now, so the results will be here soon.
We have all the evidence too.
Is this what you used?
Did you enjoy the women in pain as you pulled their fingernails?
What's that expression?
Do you admit it was your doing?
Just because you found some tools in my car,
are you saying I pulled out this woman's fingernails?
Kang Jae Deok lured them,
and you kidnapped them.
The two DNAs are different, meaning Kang Jae Deok took care of two,
and you took care of the rest. Right?
Why? Did Kang Jae Deok say no at first?
So you ordered him to do this...
to control him?
You've watched too many movies, Detective.
You worked at S Culture with Kang Jae Deok, right?
Kang Jae Deok.
What's he doing these days?
Yoon Jeong Sub, listen carefully.
We have more than plenty of evidence,
so you'd better quit that useless pretense.
Then just follow the law.
Yoon Jeong Sub is acting tough on purpose.
It's an instinctive defense mechanism.
He's not the type to crumble down with our usual methods.
Where is Song Yoo Kyung right now?
Yoon Jeong Sub, just you wait.
Once this comes out, you won't be able to break free.
Team Manager Kang.
No, you can't do that.
Song Yoo Kyung is probably terrified right now.
You're the one who can understand her position the best.
I know you can persuade her.
But...
We can't stall any further.
If things get more delayed, there won't be any way to save Yoo Jin.
The decision is up to you.
What would you do?
I'm really bad at...
talking to strangers unless it's online.
I heard about your story, Yoo Kyung.
And...
I remembered what I'd forgotten about me.
Was it when I was 21?
He had a nice voice.
I just kept thinking about him.
I wanted to do everything with him, so I learned hacking.
The man was an expert in it.
- What in the world! - Oh no!
- And then... - My money!
- I found out... - Oh no.
that I'd killed a person.
One day, I went home.
And the house was completely empty.
I lost everything at that moment.
At first,
he slapped my cheek.
That was the start of it all.
I'm sorry.
It only grew worse.
It's all my fault.
He was everything to me.
He took me in when I had no one to rely on.
No one can hurt you.
They need your help.
You can help them.
I'm so scared.
We need you, Yoo Kyung.
Only your husband knows where Kwon Yoo Jin is.
If we found out where she is, we can save her.
Will...
Will it really be okay?
The two of us...
can save our past selves.
All on our own.
I...
I want to save that woman who was abducted.
Kwon Yoo Jin...
Where is she right now?
The police told me you killed someone.
Did you really kill someone?
You didn't, right?
Why did you do it?
It has nothing to do with you.
I can't believe that you killed someone.
Let this woman out.
I'm not going to say anything.
This is why...
I told you not to hang out with people like Kang Jae Deok.
It'd have been better if you'd listened to me.
Kwon Yoo Jin...
Where is she right now?
Why do I have to answer?
Wake up, Song Yoo Kyung!
They want to frame us for murder right now.
Five people.
It's five people.
Honey.
Please tell me.
I told you.
It has nothing to do with you.
So just leave.
Hey, let her out and you guys find where she is.
Why aren't you leaving? Get out right now!
You...
You're really not going to talk?
I...
I will never talk.
Did my husband...
really kill those women?
You just need to fill out some papers as a testifier.
And then you can go.
I know it's hard, but please cooperate with us.
How am I supposed to continue living?
You have been really brave.
You can do anything by yourself, Yoo Kyung.
Thank you.
Just give me a moment...
Just give me a moment to get some fresh air.
Kang Jae Deok lured the victims,
and you abducted them.
There are two different DNAs, which means...
Kang Jae Deok killed two,
and you killed the others, right?
The orderly fashion of...
Yoon Jeong Sub's house...
does not exist in the photo.
And Yoon Jeong Sub and Kang Jae Deok's...
main trauma...
does not concern hatred for their mothers.
Then why did these two...
commit such crimes?
He's acting tough on purpose.
He pretended to be tough while Hyun Jun was interrogating him.
What does he do nowadays?
Follow the law then.
He is not being hostile.
He is being defensive.
It looks like he's acting.
Turn on the footage of Song Yoo Kyung.
Yes, sir.
She's not scared at all.
She looks scared to me.
Stop.
Rewind.
She looked at his eyes first.
- Pardon? - If she was scared,
she would have looked somewhere other than his face.
She wouldn't have been able to look him in the eyes.
Even while looking at horrible pictures of the dead bodies,
she's neither scared nor horrified.
That woman...
is too calm.
He is watching Song Yoo Kyung.
He is...
waiting for her order.
Will you really not tell them?
Wait.
This sounds like she's checking something.
Wake up, Song Yoo Kyung!
They want to frame us for murder right now.
Five people.
It's five people.
Did you really kill someone?
You didn't, right?
Why did you do it?
She's appealing emotionally to him...
and ordering him to confess his crimes.
It has nothing to do with you.
Let this woman out.
I'm not going to say anything.
And she's ordering him...
not to involve her in this case.
You...
