Since 2015, there were these three murder cases...
that took place in Seoul and Gyeonggi Province.
- These three unsolved murders... - Excuse me.
have something in common.
Their bodies were all found by their parents.
But this time, he sent a video instead of a body.
He's pursuing pleasure.
It will be worse for parents to face their children suffer...
than to see their dead bodies.
The location of abandonment doesn't have anything to do with her father.
The name written on the CD was Eun Jung's mother.
The criminal's target...
was not the family but their mothers.
The S tattooed on his wrist...
referred to S Cult.
Kang Jae Deok. He runs the website S Cult.
- I'm not going to prison. - Kang Jae Deok!
They made a fake sadistic video...
on a secretly operated internet show.
Who are you?
Do you know anyone in here?
This man.
We're here to see Yoon Jeong Sub.
He's usually nice and good to me.
I didn't want to betray him.
He's the man I love.
Let's...
save ourselves from back then.
She isn't frightened at all.
She saw pictures of victims brutally murdered,
but she is shockingly calm.
What?
(Episode 7)
Was Song Yoo Kyung really the one who tortured and killed the victims?
Was it really her?
I understand how you feel. But our priority...
is saving Kwon Yoo Jin.
There's something I just can't understand.
Why did Song Yoo Kyung come back, knowing she was being chased...
by the police?
Because of her faith...
that she could control Yoon Jeong Sub.
I'm sure what she wanted to avoid most...
was our finding him before finding her.
Because...
that would mean she could not completely control him anymore.
(Kang Ki Hyung)
She thought she could control him as long as she was with him.
Now that's confidence.
Look into Song Yoo Kyung for me.
Yes, sir.
Yoon Jeong Sub thinks he's in full control,
and that he and Song Yoo Kyung are equal.
But in reality, he is being dominated.
Based on the video,
he feared Song Yoo Kyung.
I'm sure he didn't want to admit to who he was behind the mask.
That's why he thinks he's protecting Song Yoo Kyung.
On the flipside,
I'm sure the feeling that he's being used by her...
is creeping into him and making him nervous.
We have to use that,
if we want to find Kwon Yoo Jin.
- Let's begin. - Yes, sir.
Song Yoo Kyung.
What happened?
I was nervous,
so I went to him.
Were you assaulted?
I don't know why he did it.
Don't keep anything from me. Tell me everything.
The truth is,
I can't drink.
He's usually kind and nice.
But...
once he drinks...
He's breaking.
He's afraid.
Good.
Let's tell him we know she's the killer,
- and begin questioning him. - No.
He knows what we're after.
I'm sorry for lying.
I didn't know what to say. I was afraid.
He's the man I love.
He looks at peace again.
It looks like he's smiling at the camera.
We need something to cut the tie between them.
There is a way.
Do we have all the video files we got from S Cult's server?
Do you mean the Internet program videos?
Yes. We can make fake evidence with them.
Evidence?
Evidence that Song Yoo Kyung planted in advance...
to make Yoon Jeong Sub look like killer.
And we found it.
I think I can understand...
why Song Yoo Kyung did this.
A doctor who treated Song Yoo Kyung when she was 15...
found she was sexually assaulted and abused, and called the police.
Help me.
Please call the police.
The police named her step-father as the prime suspect.
Something isn't right.
If her trauma began with her step-father's sexual assault,
why does she want to hurt the victims' moms?
How did the case end?
Not guilty.
Song Yoo Kyung retracted her statement.
She said nothing happened.
The truth must be hidden in there somewhere.
The record shows her mom went to the police station.
What if...
her mom stopped her from testifying?
It's common for minors...
to make false testimonies because they're afraid or threatened.
Even with the child who died recently from domestic violence,
the child told the police that nothing happened,
so they stopped investigating.
Then the incident happened afterward.
The wounds are evident,
and her medical record confirms she had sexual intercourse.
Yoo Kyung. Tell them the truth.
Did your dad really do that?
Yes, tell us the truth.
You don't have to be afraid. Don't worry.
Well...
It was that boy, wasn't it?
- Mom. - I said not to hang out with him.
Why did you do it? Why?
Still...
The truth is...
Mom...
What my mom said is true.
I...
I lied.
During the worst moment of her life,
her mom, whom she trusted most, didn't protect her.
The memories of that day probably started all of this.
We have no time to lose.
What happened?
Okay. I'll go in first,
so give me a sign when you're ready.
You don't need to lie in order to protect Song Yoo Kyung anymore.
We've already found evidence...
that she's the real killer.
Don't lie to me.
I won't fall for it.
We know why you said, "five people" to her.
Get it together, Yoo Kyung!
Those jerks are trying to frame us for murder.
Five people.
Because the number of people you and she killed...
was three, not five.
No!
The DNA found on the body...
of the first two victims, Yoo Hye Jin and Choi Eun Seo...
was confirmed to be from Kang Jae Deok.
I'm sorry. I'm so sorry.
Once the fearful Kang Jae Deok...
refused to kill any more people,
Song Yoo Kyung approached you, his friend,
and continued with you from the third murder.
Kang Jae Deok was a fearful person.
Enough to choose death over prison.
Based on his profiling, he couldn't keep souvenirs...
to relive the moments he murdered the victims.
Thus, he did not put the nail...
in the pad himself.
Song Yoo Kyung had planned to tie you and Kang Jae Deok together...
as accomplices and get out of it scot-free.
Drop the lies. Where's Yoo Kyung?
He's starting to react.
It's ready. Let's begin.
Here.
Song Yoo Kyung.
Song Yoo Kyung is...
How did it go?
Where is it?
Did you check the content?
Okay.
Tell me!
What did you do to Yoo Kyung? Where is she?
Tell me!
What did you do to Yoo Kyung?
Don't you dare touch her. I won't forgive you.
I'll kill you all.
I'll rip you to shreds and kill you all.
Please...
We found this in your home. When did you film this?
What are you up to?
We were right.
You're not the one in the mask, are you?
Song Yoo Kyung planted it in case of a situation like this.
According to her plan, you and Kang Jae Deok...
killed all five of the women.
I'm sure she needed evidence to prove that.
You're not special at all to Song Yoo Kyung.
To her, men are just tools.
You were used like Kang Jae Deok. You were expendable.
Shut it!
She is insisting...
that you threatened her and made her partake in the crimes.
Once she feels she can't get out of it,
she'll change her attitude and help with the investigation.
Choose.
It's your last chance.
Wait.
Did Yoo Kyung really say that?
That I threatened her, and she had no choice?
Min Young, there's only one road that leads to the reservoir,
so wait by the entrance of the road.
Got it.
Please!
Please, don't do this!
Please... Please just kill me instead.
Please just kill me!
Come on. Why would I kill you?
Okay.
Then...
I'll just finish you.
This is the place.
Kwon Yoo Jin was being held here until recently.
It's Song Yoo Kyung.
Hang on tight.
Careful.
Song Yoo Kyung. Calm down.
Let her go.
Put the knife down.
What's wrong with killing a harlot like her?
I did nothing wrong.
I know. Please stop here.
You've suffered too much to give up on the rest of your life.
If you stop here, it'll be better than it is now.
What do you know?
Do you know how I've lived?
How painful my life has been?
Song Yoo Kyung.
I'm going to shoot.
Let go!
I'm going to kill her!
I'm going to kill them all!
Let's save ourselves from back then.
With our own strength.
Kwon Yoo Jin!
You can never live the life you used to.
Just like me, you...
You will suffer in agony for the rest of your life.
- They're here. - Move aside.
(Court)
Bring Eun Jung back to life.
Bring Eun Jung back to life now.
Eun Jung. Bring Eun Jung back.
- Why did you kill those women? - Please explain.
- Please say something. - Why did you do that?
Yoo Kyung.
I'm sorry.
It's all my fault. Yoo Kyung.
Bring my daughter back. My daughter.
- Die. Are you even a human? - How could you do such thing?
Bring my daughter back.
If there was anyone who helped Yoo Kyung to be brave,
this wouldn't have happened, right?
Are you blaming this on the people around her?
What?
That's not how I see it.
Not everyone does such a thing...
because they were abused when they were young.
If you think of the victims' families,
what she has done to them...
cannot be forgiven.
"Those who commit evil deeds..."
hurt others, but they hurt themselves the most."
Socrates.
Team Manager Kang. Here's the briefing on Song Yoo Kyung case.
Thank you.
How's your wound?
This is nothing. I'm fine.
It was a good profiling.
I still have a long way to go.
It just came to me because it was in the book you gave me.
No.
If it wasn't for your judgment and bravery,
Kwon Yoo Jin would've been killed.
You saved the victim.
That makes me want to study harder.
I'll be a great profiler just like you.
(Personal Information, Kim Yong Chul)
(List of Evidence)
I'm on the way. Please send me the backup.
As I had asked, I need you to keep this a secret.
Two months after Go Young Min was accused of assaulting a minor,
he is cleared of the charges,
and leaving the prosecutor's office.
While advocacy groups continue to argue for his imprisonment,
his lawyer, Ha Yoon Man, of Ha and Jang...
says he is not guilty.
Don't. Don't come near me.
Let me go, right now!
Here the question.
It's about a female college student...
murder case happened in Chungbuk, Yo-dong on March 20, 2001.
It had no trace of blood, evidence or witness.
There was no sign of sexual assault.
It's not like the criminal was after valuables.
Here, the criminal took something very unusual.
What did the criminal take...
in this extended cold case?
A chopped hand.
What's wrong with you, Hyun Jun? You're not realistic.
You're just so perfect.
Move on. Move on.
It's about one of the most famous cold cases.
It's a question on Cheonju-si Nadeul River case.
Among 136 suspects for the case,
one suspect was most suspicious.
Here's the hint.
The biggest topic on the news lately...
Go Young Min.
How did you know?
I was one of the suspects.
- That's not funny. - Don't lie.
Let me make a call.
(NCI Ha Sun Woo)
Tell me if you want to stay alive.
Was it you...
14 years ago?
I told you before.
I...
I didn't do it.
He asked me...
the same question.
It's not me he was after.
From the beginning, he...
What?
Who is he?
Say it. Say it. Say it now.
Who's behind you?
- Don't move. - Freeze.
Detective Kim.
- There he is. - Lawyer Ha.
There was a report that stated that Go Young Min...
secretly ran a punishment site through a borrowed name...
and that he spread videos of minors getting punished...
until they died. Is this true?
Is it true that you didn't know anything about Go's crimes?
- Please speak. - Please say something.
- Say something. - Is it true?
- Please speak. - Lawyer Ha.
- Lawyer Ha. - Say something please.
- Morning, Han. - Morning.
(Current State of the Online Punishment Cafe Case)
The high school girl murder case in Nadeul River in 2003.
What was the number of suspects who received a DNA test...
over the past 14 years?
Good morning, everyone.
Sun Woo.
Why didn't you come to the dinner last night? I was waiting for you.
Sorry. Something came up.
Isn't he the chairman of Ha and Jang?
What's he doing here?
Hello. Yes. Okay.
Yes.
Chief Director wants you.
What's the reason?
Why?
I heard that the report from the internal investigations team...
is pretty intense.
Get to your point.
Have you forgotten...
what you said to me when NCI was established?
Did you call me?
Have a seat.
Sun Woo.
Before it gets noisy,
follow me.
Why do you keep crossing the line?
It's none of your business. I'm just doing my job.
You don't need to care about this.
The world...
is not as simple as you think it is.
If you're done, please leave.
Watch your actions.
Don't ever visit me.
Go Young Min, who was imprisoned three months ago...
for assaulting a minor then cleared of all charges,
was found dead.
It is causing an uproar.
Based on evidence they had, the police had been...
investigating him.
However, when the Prosecution's Special Crimes Division...
went to arrest him,
they found him dead with multiple stab wounds...
shocking many people.
The police say that...
(Nadeul River Case Suspects)

(Scholarship Presentation Ceremony)
(Kang Ho Young)
The number you have dialed is not available at this moment.
He was stabbed in exactly at the pressure point.
The knife narrowly missed the bone...
and went deep into the organ.
But what's really strange is this. Take a look.
It looks like someone pierced his ears forcefully.
According to forensics...
Here.
The deceased victim, Han So Min, didn't have her ears pierced.
That means it doesn't belong to her.
You should call forensics.
(NPS)
These are the additional pictures for the Go Young Min case.
At first, I thought it was nothing.
But it seems strange.
Does anyone other than forensics know about this?
No. I did send these documents to a detective I know at Ilyang,
but it was before I found out about this.
Ilyang Police Station?
Yes.
(Ilyang Police Station)
It was a case from the Special Crimes Division.
A person I know was at the scene.
He was really surprised...
because an NCI agent was there.
So?
When he arrived, it was already over.
The victim called Han So Min...
was already dead.
And the female agent was screaming like crazy...
while holding onto the dead body of Go Young Min.
He thought she might have had a personal grudge against him.
She was nearly out of her mind.
And...
here.
I might not know much, but if the Special Crimes Division...
and NCI are involved, this must be serious.
From the beginning, he...
- A present? - It's for our wedding anniversary.
"HW".
You put my initials on it?
Thank you.
I will teach you properly.
- A present? - It's for our wedding anniversary.

(A Profiler's Personal Revenge!)
(The Devil's Psychologist, Yoon Hee Chul, the Korean Ted Bundy)
(The Revenge of the Profiler)
It was revealed that after the culprit killed his family,
Yoon Hee Chul, a profiler for the police...
has been killing people related to the culprit for seven years.
He has shocked the nation once again as it was revealed...
that he has buried the dead bodies in a mountain...
within 1km of his house.
Yoon Hee Chul has accepted a visitor for the first time in 10 years.
Ironically,
Lieutenant Kang Ki Hyung,
who has arrested Yoon Hee Chul after three years of investigation,
was in fact,
his student in the past.
These two have worked...
I wanted to ask you something.
I know why you are here.
You must be...
very curious about what it is that the Reaper wants.
What do you think would make...
a man who doesn't fear death...
feel desperate?
He will try to destroy all the people around you.
He would be thinking about...
what matters to you most at each moment.
Kang Ki Hyung.
I need fresh air to breathe.
Before I die, about 15 years...
I have no authority to make a deal.
You will have to.
You won't be able to confront him without my help.
When your heart has been torn apart...
and drowned in hot water...
and cold water a thousand times,
you'll fall to the bottom...
and feel devastated.
Only then...
will you understand my words.
If you get me what I want,
I will tell you a way to catch him.
Kang Ki Hyung.
Keep this in mind. He will never give up.
Go Young Min, who was a sex offender,
was murdered mysteriously.
Many problems have been brought up regarding the case.
- Sun Woo. - The essential problem...
with the current industrial system...
have been brought up as the main issue.
Who do you think the culprit is?
There seem to be a lot of problems with that case.
If the victim's family had killed...
Go Young Min,
why would they have gone through such a dangerous and had process?
Don't you think so too?
Do you think that a victim who has lost someone...
could have killed someone...
while letting Han So Min die as well?
In such cases, it is highly possible that the culprit...
is someone you'd never even think of.
(Kang Ho Young)
I need to get this call.
Min Young, cheers.
Hello?
It's me.
Why didn't you get my call?
Do you know that Go Young Min is dead?
I saw it on the news.

I...
have something to show you.
I can't talk about this over the phone.

The first witness of the case.
The first witness?
What are you doing?
(NCI Nana Hwang)
While I was restoring the data you sent me,
I found something.
It's strange.
Send it to me first. Let me see it first.
I just sent it.
This...
isn't what we think it is, is it?
Hey, Sun Woo.
Open the door, Sun Woo.
Sun Woo.
Mo Ji Eun.
You know her, right?
Why did you hide it?
What is your plan?
Fine.
Let's talk about it later.
There's something more important.
Is he back?
He left Team Manager Kang's wife's...
earrings at the scene of Go Young Min's murder.
Is it true?
Why?
Were you going to keep it a secret?
Are you out of your mind?
Have you thought about how Team Manager Kang would feel...
when he finds out about this?
I did.
I didn't have any other choice.
I thought over it, but I couldn't find the answer.
No matter how much I think about it,
my conclusion is always that I mustn't do anything...
to make Team Manager Kang suffer.
Why do you think he was after Go Young Min?
I think he's not only after Team Manager Kang...
but the whole team.
Destroying the team...
will make Team Manager Kang suffer more.

Deputy Manager, that will give us trouble.
No. That's not what you said before.
Yes. Wait.
I sent it to you for sure. Have you checked?
They contacted me to confirm they checked it.
No sir, I'm not trying to pick a fight with you.
Deputy Manager.
I'm on the way to my son's school.
I don't know. He got himself in trouble again.
Shoot. Goodness.
The number you have dialed...
My gosh, this jerk.
My goodness.
I know.
Yes.
I will be there, and then...
Hey, wait.
Excuse me.
- Excuse me. - What is it?
I stopped because I had an urgent matter to attend to.
So what?
I kept giving you signs to go past me.
You should drive properly. Who are you to tell me to stop?
- My gosh. - I mean...
Yes?
There are five rooms there, and it's very luxurious.
Yes.
I can send it now.
Ji Young, where are you going?
You shouldn't go out today.
I need to talk to you.
Ji Young. Jang Ji Young!
The number you have dialed is not available at this moment.
Why didn't you pick up my phone calls?
And by the way, I...
Today I... Honey.
What would I do with a man like that?
I'm living with him out of pity.
Set one's sight on the front sight. Stop breathing.
And shoot smoothly.
I know all that.
Do you know what your problem is?
You don't keep your eyes on the target.
Keep your eyes on the target even after you shoot.
And make an isosceles triangle by bending your arms.
This way, you can minimize the recoil.
Keep your breath steady.
Keep calm and try again.
You shot the target perfectly on lane five.
I must be a great teacher.
Give me a high five.
I...
was targeting on lane four.
Lane four?
Four?
Is he back?
He left Team Manager Kang's wife's...
earrings at the scene of Go Young Min's murder.
Is it true?
Why?
Were you going to keep it a secret?
Are you out of your mind?
Why do you think he was after Go Young Min?
I think...
he's not only after Team Manager Kang...
but the whole team.
Destroying the team...
will make Team Manager Kang suffer more.
You...
should tell Team Manager Kang before it's too late.
We need to be more careful.
Is that the only reason?
As time goes on...
I will tell him later.
All right. Let's talk later.
Rumors surrounding the shooting incident on the road...
are being spread fast on the Internet,
and the people are in more fear than ever.
Although a shooting incident...
has happened in the middle of the road in the daytime,
the police has not been able to identify the culprit...
What is that crazy person doing?
What are you doing?
Hey, are you out of your mind?
(23 Ju 1633)
These are photos of the victim...
who has been shot on the 29th at 3:00am near Yangchon-dong,
at the access way of the ring road.
The victim died on the spot.
This shooting incident happened one week after...
the first case, which happened on the 21st.
Fortunately, the first victim has survived,
but she hasn't gained consciousness yet.
We're not in the US or Mexico, right?
Actually, shooting incidents in Korea...
have been increasing every year.
Last October, a police officer was shot...
by an individual at the Mount Opae Tunnel.
They found 17 handmade guns...
and explosives at his house.
How about black box footages or witnesses?
The first incident...
happened at a road construction section,
so there were no CCTVs that were actually working.
And it's hard to find a witness...
as there were only a few cars.
The second incident happened at a national highway with only few cars,
and it happened at dawn, making it hard to track.
I'm looking at a black box footage sent from the police station.
The black sedan that belongs to the culprit...
looks blurry on every footage.
How are the two victims related?
There is no relationship except that they are women in their 40's.
If there is no relationship between the two,
it could be a random hate crime.
Wait.
Let's compare the victims' pictures.
They look similar, but in fact, they are different.
If you look closely,
the second victim's wound...
looks larger.
Do you mean there are two culprits?
It could be a copycat crime.
No, there is only one culprit. He cut the muzzle of the gun.
Gunpowder was mostly found...
on the left cheek of both victims.
They were shot with...
a long-necked rifle through the window of the passenger seat.
He learned from the experience...
what he has to do if he wants to shoot easily.
Are you crazy?
He's...
picking up what it's like to murder.
That's why we must take charge of this case.
The first round of investigations were conducted on...
people who have easy access to guns like veterans and military people.
However, it was reported to be unsuccessful.
It won't be easy to chase him.
If you want, you can just watch the video on a private gun...
manufacture website to make one yourself.
Then you're saying the criminal made a shotgun himself?
There's no regulations on illegal private guns...
which makes it hard to locate him.
It's a possible scenario.
If the car is this bad, the driver must be...
I think it really was a private gun.
The bullet holes are all different sizes.
It means the force on the bullet is not consistent.
There's another shooting incident on number 11 highway.
This kind of murder is like drug.
He'll look for the next target soon.
- Captain. Please wait for a bit. - Get out!
The criminal's losing his sense of reality.
The world he sees has changed,
and his role has changed.
What's the rage in his heart?
He'll be out of control.
Only if we were any faster.
Don't make any hasty conclusions.
Nothing's more important than saving people.
We'll reveal the suspect profiling to the public for report calls.
Have you got the outline of the criminal?
Please tell us about the current situation.
You know the criminal will commit a crime again.
Hurry up. I need to start profiling now.
