- It's dangerous. - What is?
I've gained weight. I'm heavy.
You're not.
What?
Why did the power go out suddenly?
I'll go check the fuse box.
Watch out when you go down the stairs.
Okay.
What was that?
Honey.
Chungmyung Police station requested cooperation...
related to a serial sex offender.
6 months ago, 4 university students were raped...
in Christian university located in Chungmyung.
4 female students were raped once every 10 days.
It stopped for six months,
then it began with completely different targets 15 days ago.
The second victim, Jung Jin Hee, 37.
She was raped 15 days ago.
She's currently in Bookyung where her parents live.
There was an additional rape...
a week ago in a house in Palbongro, Chungmyung.
Her name's Choi Yu Rim, 34.
Her boyfriend, Kim Jae Seok, was with her at the time,
and the culprit smashed the back of his head.
Compared to the previous victims,
the current victims are in their mid 30s.
There's no correlation between the victims.
How do you know it's done by a same person?
The culprit left a same voice message to the victims.
I can give you everything you want.
We were lucky to restore one of the victims'...
broken cell phone.
I can narrow down the age by analyzing the voice.
The culprit's exposing himself through the message...
as if he's showing off.
He's not trying to hide himself at all.
Upon hearing the message,
it sounds like the culprit knows the victims well.
Was it possible to assume suspects in the initial investigation?
No. Not yet.
The message's distinctive, but what's more unique is that...
starting with Choi Yu Rim a week ago,
the culprit left a witness on purpose.
Did the boyfriend witness the scene of crime?
Yes. The boyfriend was there,
and he lost his consciousness.
If there are several victims,
they could outline the culprit's features.
The thing is, the culprit raped the victims so cruelly...
that they can't remember it.
Even their testimony is ambiguous.
They said he breathed heavily, had sharp appearance,
and he wore a cap.
Any connections with ex-convicts?
Police secured the culprit's hair from the scene of crime...
and went through a DNA test,
but couldn't find any match.
First victims were religious university students.
He had six months...
until he raped Jung Jin Hee and Choi Yu Rim.
He selected completely different crime targets.
It's important to figure out why the culprit changed his targets.
We need to find out what the six months' time means...
to the culprit while he stopped the rape.
How's Choi Yu Rim's condition?
She's in hospital.
Sun Woo and Min Young can go talk to the victims in hospital,
and Nana can join us at the police station.
What? Me too?
You begin the interrogation.
When we look at the first victims' houses,
they either lived in a studio or a rooftop house.
Their neighbors could hear their scream.
Why didn't they hear anything?
There's no trace of break-in at the victims' houses.
No one knew until the victims reported.
How did he get inside the house?
The culprit's committing crimes...
using his own pattern.
He made the victims to open the door for him...
as if he was invited.
He might have a record of burglary.
No. I don't think so.
If he was going for an empty house,
he wouldn't harass the victims this much.
The culprit raped the victims multiple times in the same place.
Multiple times?
It turns out Palbongro area where Choi lives...
had a power outage for two hours on the day of the crime.
The culprit was aiming for the moment...
when the victim's scared in the dark.
The culprit wanted to see the victims scared in the dark.
The victims testified that...
before they were raped, they heard a loud noise outside.
He was trying to distract them.
That's when he got into the house.
- I'm Team Manager Hong Sang Mi. - I'm Kang Ki Hyung.
I'm in charge of this case.
As you know, my sexual crimes team is simple.
It's cost-effective.
You requested us as soon as you got the report.
Yes.
I thought I should find out the reason he changed the targets...
through profiling to narrow down the suspect.
I heard you were Agent Ha's senior...
when she just became a police officer.
Yes. We drank so much every time the culprits we caught...
were released.
I can't imagine Sun Woo doing so.
You'll have to talk through with the victims.
You'll find female agents more helpful.
If you need my help, I'm more than willing to help you.
- Sure. - Okay.
(Emergency Center)
Why did they tie her arms up?
I heard she attempted suicide multiple times.
Choi Yu Rim?
We're...
from NCI.
Do you remember anything new...
that happened on the day of the crime?
I know it's hard,
but try to recall the memory please.
Do you remember the culprit's face?
When I close my eyes,
I can see his face.
I can't even open my eyes anymore.
Please.
Please...
How long do I have to...
It's all right.
Let's stop here.
We'll come back later.
Analysis of his voice...
shows that...
the culprit was a male in his mid to late 30s.
He would have been someone...
who could watch the victims all day.
We investigated and interrogated...
people around the victims for the last year,
but we could not find anyone who was suspicious.
The culprit would have no personal relationship with the victims,
but he would have talked to the victims at least once.
He would be nice looking and good at conversations.
The victims probably don't remember the culprit...
because they didn't feel hostility towards him.
It would be possible if he was someone that everyone can meet.
He could be a real estate agent,
service technician, internet installation engineer...
I'm sorry to interrupt,
but we have interrogated every one of those people.
No, you must have made a mistake.
The victims were of different age,
they had different jobs, and they led different lives.
Seeing as the culprit set them as the target,
he must have lived near the victims...
or had jobs that had something to do with the victims.
(Emergency Center)
At least the weather is nice.
He would have watched...
the victims from where he worked.
He would have only committed the crime when his fantasy could be met.
This means...
that he has access to...
not only the victims but to everyone.
- Min Ah? - That'd be me.
- Thank you. - He could be a cable engineer,
a gasman, or a maintenance engineer for water purifiers.
If you widen your thoughts from there,
He would work at a place where women can easily talk to men.
He could work at a beauty parlor, a cosmetics store,
a library, a post office,
a delivery service, or a convenience store.
Did anyone suspicious come to you after the incident?
I told you everything six months ago.
Can't you just check the records?
Sun Young,
I know this is hard for you.
But the number of victims is increasing.
I'm sorry, but we need to know.
I'd like to ask you again.
Was there anyone near you...
who kept circling you quietly?
Ms. Hong,
I'd like to talk to Sun Young alone.
I'm sorry.
We should have been more considerate.
I'm an information specialist at NCI.
I'm not an expert at profiling.
There is no one in particular...
that I can think of.
Is there anyone who suddenly quit a club, a gathering,
or took time off from school?
It wasn't someone around me.
I know that much.
We think that the culprit...
has been stalking other victims.
Did the culprit...
try to talk to you about something?
I don't remember anything else,
but...
he had said something really scary to me.
Look at me.
Look.
Look at me.
The police...
told me that he hadn't killed me or anything,
so I should forget about it as if it was a bad dream.
They said there were many people who were killed in the end,
and that it was a relief.
But...
is it really a relief?
Before committing the crime, there's order.
But during the process, he becomes disorderly and violent.
That means...
he's angry when he commits these crimes.
That's probably why he is violent.
"I heard a sound after the electricity went off."
"That's when the culprit came inside through the open door."
It's not like other crime patterns.
Especially sexual assault crimes.
Before committing the crime,
he plans it inside his head,
and then he carries it out.
He must get excited while he watches...
the victims panic in disorder...
after he turns off the electricity.
Please check if there were...
similar cases like this in the past.
I was actually searching for cases.
I'll conduct a nation-wide search...
on cases in which the culprit stole from or broke into houses...
while the electricity was turned off.
All right.
Are you guessing that the culprit committed other crimes before this?
Seeing as he plans his crimes,
it's likely that he started with burglary or breaking into houses.
If you look at the crime patterns, he's very bold...
and confident.
During his second crime, he didn't try to hide anything.
He even left a witness to his crime.
He leaves messages and witnesses,
makes the victims look at his face forcefully,
and vents his violent anger towards the victims.
What do they mean?
They could have something to do an experience in the past.
And we need to find that story.
The fact that he has left a witness could be a message in itself.
The culprit...
is asking someone to keep an eye on him.
Whoever it is,
it must be someone from the culprit's past.
There must be more victims that we don't know of yet.
Only 11 percent of rape victims report to the police in Korea.
The victims from the first case were all Christians.
It would have been harder for them to report.
The culprit would have taken that into account as well.
He would have chosen victims who are unlikely to report.
Why do you think he stopped for six months?
There must have been a reason why he had changed his mind.
It would have something to do with the reason he changed his targets.
It's been a while since you worked together,
and yet it looks very familiar.
I didn't know she started her career here.
I didn't...
know that she'd be so successful.
Is NCI going to be officially leading the investigation?
The culprit would be looking for his next victim.
We must move before he does.
Was there anyone suspicious around the victims?
I think I have something.
Six months ago, a female student from Chungmyung University...
committed suicide.
Did she report any sexual assaults?
No, she didn't.
She committed suicide during the period...
in which the culprit had stopped committing his crimes.
I don't know why...
So Hee has anything to do with the incidents you are talking about.
Have you...
heard about the suicide incident in Chungmyung University?
Of course.
The story was all over the media.
We think...
that So Hee has something to do with the incident.
What are you trying to say?
That's not possible.
My daughter...
wasn't someone who would be the target of such crimes.
Honey.
Did So Hee leave a will?
I'm sorry,
but may we take a look at it?
There was no such thing.
Team Manager Kang, I searched...
for similar cases in the past as you asked me.
There have been multiple cases...
that show similar traits at the cities on the outskirts of Seoul...
like Moohyun, Hajeong, Songro, and Yuljeong since five years ago.
Five years ago,
there have been housebreaking cases in Moohyun.
But since the incident that happened in Hajeong,
it was turned into burglary.
All the cases happened after there was no electricity.
During the last crime that happened in Yuljeong,
the culprit violently killed...
a dog that was in the yard.
All the victims from the first and second cases...
have something to do with the fact that the electricity had gone out.
The suspect would choose a target in advance...
and cut the electricity off on purpose.
That's strange.
Look at the direction the suspect moved.
It starts here, and it connects all the way to Chungmyung,
as if this is his final destination.
The final destination?
It must mean a case that started in Chungmyung...
became the trigger.
Nana, let's narrow it down to men in their 30s...
and focus on people from Chungmyung.
Let's do the background check for past cases again.
Yes, sir.
Sir, this is hard for us to bring up too.
We'll return So Hee's will after the investigation.
It's hard?
What's hard? If it's so hard,
why did you come six months after she was buried...
to ask me about how she died? How does this make sense?
Both my husband and I...
are just barely living on.
I'm very sorry that we're asking you at this time,
but we don't want more people to be victimized like her.
We'll do our best to prevent it.
I'm sorry,
but we don't want to help you anymore.
Wait.
Our daughter...
was very precious to my husband.
It's too hard for him right now.
We came too late.
I'm sorry.
We're her parents, but we lost her.
We should have prevented it.
Really?
You're lying, right?
(Dear fellow students, I'm writing because I need your help.)
(Reply: No way! I would die! Reply: I know who she is.)
So Hee...
was pregnant due to the rape.
(Suicide, suicide)
Mom,
Dad,
I'm sorry...
I'm a disappointing daughter.
The reason why the criminal stopped committing crimes...
was because of So Hee's suicide six months ago.
He could have felt guilty.
He must think that he killed her.
After that,
his sadistic characteristic would have magnified.
Looking at the state Choi Yu Rim is in,
it won't be long before he commits murder.
Ms. Hong told me you're a good soju drinker.
Is this true?
Well, I guess it wouldn't be so easy to be in a team...
that focuses on sexual assault cases.
Prior to leaving the team, I had to take a difficult case.
What was it?
Was it difficult even for an NCI agent?
There's always a first in everything...
whether that beginning is painful or happy.
They must have a reason of its own.
I must be here now...
because of my time there.
Sir.
There is something I have to check with Choi Yu Rim.
Did the culprit...
mention anything about children or family?
No.
Then did he say anything about his misfortunes...
or about his relationship with other people?
There was no chance for me to talk with him.
One of the victims...
found out that she was pregnant with his child...
and took her own life.
Yu Rim, did you think of something?
Actually,
I was trying to get pregnant.
I'm getting old.
I couldn't tell my boyfriend,
but I went to get consultation from the fertility clinic.
He...
didn't want a baby.
When did that happen?
I visited the clinic about a month before the incident.
Did you...
tell anyone about it?
No.
I jokingly mentioned to my friends...
that I want a baby,
but I didn't tell anyone...
that I was planning for it.
The other victim Jung Jin Hee who is also in her 30s...
had visited the same fertility clinic as Choi Yu Rim.
When did she go?
Around the same time.
She was divorced, and she wanted a child.
Check the hospital records.
The culprit must be a staff at the clinic,
or someone who can easily approach the patient records.
Yes, sir. There's one more thing.
Both of the victims...
were prescribed with Clomifene, a medication that induces ovulation.
Before the medication shows effects,
the clinic wouldn't perform any procedures on patients.
The culprit approached the victims knowing they were taking Clomifene.
If it was prior to getting artificial insemination,
there would be a higher chance they would bear his child.
If the criminal is committing sexual assault...
to impregnate his victims,
then those women were perfect targets for him.
In the beginning, he chose young and devoted Christians.
They're easy to control,
and he figured they wouldn't get an abortion.
However, when So Hee committed suicide,
he changed his target to women that want babies.
But why is he maltreating...
the victims?
He might be trying to impregnate the victims...
as a means of letting out his resentment and rage.
If that's the case, it must be connected to a trauma.
(Infertility Clinic)
I'm sorry, but whoever committed such crimes...
has nothing to do with us.
As you can see, most staff...
and patients are women here.
He could be a subcontractor, supplier,
or even from your security company.
I'm not saying we won't cooperate.
I'm saying there's nothing we can cooperate with.
It's really heartbreaking what happened.
However, you should see things from my point of view too.
As you know,
less people are getting pregnant,
and if there's a weird rumor about us,
it'll be too much damage.
We're not interested in this hospital's...
profit or stake.
One thing for sure is that...
victims were raped...
after they went to this hospital.
Can you fill this out please?
What's that form?
Excuse me.
It's a simple survey to provide customized service...
to patients.
Team Manager Kang.
Has this been leaked?
Has this...
even been leaked?
I sold this once...
to a research company,
but we never leaked patients' medical record.
I'll keep that in mind.
No.
Hold on.
Can you talk to me in private for a minute?
The police will explain to you about the related laws.
No.
Look into a research company named Happy Finding.
- Sure, Team Manager Kang. - Find out...
if it's related to the university the victims went.
(Chungmyung Christian University)
They were in charge of new students' orientation.
Okay.
Let's go to Happy Finding.
Yes, sir.
We're researching on the university students' awareness.
The first question is...
Are you sure our ex-employee did it?
I need the database of research...
from infertility clinic and Chungmyung Christian University.
You're not sure if he's our employee yet.
If you want,
we can always come back with a warrant in an hour.
Team Manager Kang. I sorted out...
single men from early 30s to early 40s who worked...
at Happy Finding from 10 years ago until now.
I have 20 on the list.
Find an employee who has a record of calling the victims.
There are three.
All three aren't related to the past crime.
They've all left the company.
We need to figure out...
a potential victim among the survey participants.
The culprit knew well about the victims' house structure.
He cut the power...
and went in through unlocked door.
Do you think it's related vocationally?
Why would you stay naked? What if you catch a cold?
Come here. Dry.
Hey, Ga Ram.
Let's go sleep inside.
Come here, Ga Ram.
There, there.
Come here.
There, there. Okay.
Let's go.
Sleep tight.
An unidentified man broke into...
an elementary school teacher Park's house last night at 10pm...
and got away after raping Park.
It turns out..
- he's a serial rapist... - A word, please.
who raped university students in Chungmyung...
for three months starting in November, 2016.
It turns out that the police...
hid the existence of the rapist...
who raped four female university students,
and two more women after them.
Unfortunately, it is still not...
NCI's trying its best to resolve the case as soon as possible.
There will be an official briefing soon,
so please don't write any speculative articles or reports.
At least the weather is nice.
Park Ga Hyun, 36.
She raised her child alone after her husband died.
- Where's the child? - In the room with Ms. Hong.
He left a witness.
It's a relief.
A relief?
The culprit locked the child in the closet.
Fortunately, he didn't see his mom being raped.
You're saying that's a relief?
What?
Did the power go out from 10pm until midnight?
Yes.
It's same as the previous crime.
The culprit left a message this time.
"Annunciatio dominae".
It means the Annunciation in Latin.
It represents the moment Gabrielle tells the Virgin Mary...
that she'll be pregnant.
He made the victims to see his face,
left a witness,
and even left a message.
It sure is his signature.
Now that it's open to the public,
he wants everyone to acknowledge him.
Park Ga Hyun has nothing in common with previous victims.
She's never been to the infertility clinic.
Do you think the culprit changed the target again?
If so,
something about the victim must've stimulated the culprit.
What's different about this case is that...
he went after a victim with a child.
What if the child left...
is a message?
It could represent his childhood.
The fact that the culprit made the victims feel his trauma...
is common among cruel criminals.
Hey, Nana.
Find out if the victim...
participated in an organization or any online communities.
Go meet the victim, Sun Woo.
Yes, sir.
I'm from NCI.
How's Ga Ram?
He's fine.
One of our agents is taking care of him.
Ga Hyun.
Can you tell me...
what happened last night?
Promise me...
that you will...
arrest him...
no matter what.
Yes.
I promise.
Hi, Honey.
Are you all right?
To be honest, it's a little hard.
May I ask you a question?
Sun Woo looks a little different today.
Do you know anything about it?
It's probably because of an incident that happened in the past.
It's the last case she was in charge of when she worked as a task force.
Six years ago, there was a case...
in which waitresses of Seowoo-dong area were abducted and raped.
Not many people cared as they were waitresses at a bar.
And there were not enough officers at the station to investigate.
That was when Sun Woo volunteered to act as bait.
She said she wouldn't have become a police officer...
if she was going to choose who deserved to be saved.
Tuck your hair on the right side if you think you found the culprit.
When we arrived at the scene, the waitress had already died.
Sun Woo had a hard time.
And she was sent to another team.
Did you arrest the culprit then?
Yes, he's serving his sentence now.
I searched for suspects at the fertility clinic,
the research company, and among people around Park Ga Hyun.
But there was no one that fit our profile.
Was there any women who filled the survey...
who could be the culprit's type of target?
Most of them were women of infertile couples.
They don't seem like women that the victim would target.
I found someone from the list of suspects...
whose hometown is Chungmyung.
He doesn't have anything to do with the research company,
but he was interrogated once for spreading pornography.
His name is Choi Min Ho, and he is 34 years old.
He works as a security guard at a bank.
He's the closest one to our profile.
What about the other one?
While I was researching on Happy Finding,
I found out that there have been illegal database deals.
Park Ga Hyun was in the list that has been illegally transferred.
It's from a cafe for divorced singles.
One of the members, Oh Ju Hwan, still lives in Chungmyung,
and he had been interrogated as an accomplice in a similar case.
We can't arrest a culprit because he matches our profile.
If we move hastily before we find evidence,
it could only have reverse effects.
Yes. According to his pattern until now,
he will move again in a few days.
We need to use a bait.
We can answer the survey with fake information.
I will do it.
Sun Woo.
We can't.
We don't have time.
There could be more victims if we don't.
What's my profile?
You're a deputy director at a law firm.
You are 36 years old and divorced.
You answered the survey 48 hours ago.
The research company has your information,
so he won't overlook it.
Act naturally...
so that he can watch you.
He won't wait long like he did with his former victims.
As soon as he appears, we will go after him.
So act calmly.
We want him...
to go inside.
If he trespasses, we could obtain...
evidence with his DNA.
Ms. Hong and I will be outside the house.
Sun Woo, don't forget to keep the radio connected.
Sun Woo, are you all right with this?
Of course.
Be careful.
You don't need to worry.
(Happy Finding)
All right.
Keep watching.
The culprit has access...
to not only the victims but to everyone.
He was in charge of the research for the freshmen's orientation.
The culprit was used to the structure of the victim's houses.
He cut off the electricity and went through the door he had opened.
Do you think that could have anything to do with his job?
He has a job that allows him...
to watch the victims' houses...
without suspicion...
and to obtain information...
from a research company.
Get ready.
Find out if there's anyone who works as the building maintenance...
of research company's building was involved in these past cases.
His name is Kim Hyung Soo, and he is 35 years old.
He worked as a security guard at Happy Finding.
He was booked without detention for a short while...
for assaulting his girlfriend.
Six years ago, he lived with his girlfriend named Hannah.
After the assault, she moved out right away.
About a year ago, she married someone else...
and moved out of the country.
His ex-girlfriend's marriage stimulated Kim Hyung Soo's trauma.
Yes, I believe that's what happened.
Hannah registered her marriage...
just a week before the first sexual assault.
I need you to check...
if the same security car was seen around the victims.
Let go.
(NCI Kim Hyun Jun)
The number you're calling...
Oh Ju Hwan.
You're arrested for serial rape.
- Pardon? - Get up!
What are you doing?
Hold still.
- Get him. - Let go!
Stay still.
What is this?
What are you doing?
(One missed call: NCI Ha Sun Woo)
Yes, sir.
The culprit works for the research company's security.
- Pardon? - The car of the security company...
was caught on the CCTV cameras surrounding the victims' homes.
Ha Sun Woo.
Oh Ju Hwan.
You're arrested for serial rape.
- Pardon? - Get up!
What are you doing?
Hold still.
- Get him. - Let go!
Stay still.
What is this?
What are you doing?
(One missed call: NCI Ha Sun Woo)
Yes, sir.
The culprit works for the research company's security.
- Pardon? - The car of the security company...
was caught on the CCTV cameras surrounding the victims' homes.
Ha Sun Woo.
Sir, Sun Woo isn't here.
Her phone is turned off.
I don't think it's Oh Ju Hwan.
He was calling an illegal massage parlor...
to find its location.
Find out Kim Hyung Soo's address,
and send it to Hyun Jun and the team on ground.
(Obstetrics)
Hannah.
How can you do this to me?
Move.
I don't have your baby anymore,
so I won't ever have to see you again.
What?
Did you think...
I'd marry...
a poor man without a future...
who always hits me?
I'd rather die alone...
than raise a child that looks you.
Don't you dare...
touch me anymore.
Let go!
Fine, kill me.
Kill me!
- Just kill me instead! - What are you doing?
Hey!
Kim Hyung Soo, Ha Sun Woo.
Where are you?
Where do you think he went?
Yes.
I need you to check if Hyung Soo and Hannah...
had a place registered as home together before.
After that, track for the vehicle nearby.
Okay.
I found Kim Hyung Soo's car.
In 2011, Kim Hyung Soo and Hannah...
registered for the same house.
This is the address.
The area is under redevelopment right now.
It's currently vacant.
Were you waiting...
to catch me there?
Are you looking for this?
You're just a weak woman...
without this.
That's who you are.
Kim Hyung Soo.
Is this how you treat women?
NCI agent...
isn't much different.
What would you know?
You must not know me.
Once you get to know me,
you'll change your mind.
If you realize how much they wanted me...
and liked me,
you'll be dying to have my child.
No.
I know very well how people like you are.
You never dated a woman properly.
All you do is try to overpower them.
If you don't treat them harshly,
you can't even feel anything. You're a perverted sadist.
That's what you are.
You were probably just as horrible when you were young.
Someone with a proper past...
wouldn't treat women like you.
So you know me well, don't you?
Shall we check?
Let's see how different you are compared to other women.
How does it feel? Does it feel real now?
Shall we check?
No woman has ever looked at me like you do.
It excites me.
Stay still!
You'll feel good soon.
I said, stay still.
I told you, you'll feel great.
Let me ask you one thing.
Why does someone like you want a child?
See?
You also want to know me, don't you?
You like it, but you act like you don't.
You act clean, but you're dirty.
You pretend to be chaste when you're not.
Come here.
- No. - Follow me.
