What happened 12 years ago?
What happened?
The forked road envelops two worlds.
That day, our two different choices...
changed our fate.
Rain. 9:35pm. And...
The same train operated every time it rained?
All of us live many lives simultaneously.
You crossed over the boundary.
It was you. It was all your doing.
12 years ago, and the bodies found here.
How will you prove that?
Live in silence.
Unless you want to lose something else you value.
This is all because of Seo Jae Chul.
It's been over 10 years, but I still feel miserable.
And I loathe him so much.
I don't get why this had to happen to me.
It makes me so angry. I want to kill him.
The murderer's son and the victim's daughter.
You said that's our beginning.
Wait for me. I will prove that...
that is wrong.
How is my mom's necklace...
(911 Emergency Services)
Based on rigidity, she was dead for over three hours.
And based on time of death, Kim Jin Woo's not the killer.
For this much overkill,
do you think she upset someone other than Kim Jin Woo?
It's not just overkill.
She was strangled to death first,
and then her head was bashed in. Deliberately.
Do you remember? 12 years ago, there was a case with the same MO.
The Mukyeong Residential Murder.
The same MO and same signature.
It's a serial killing.
The killer apprehended at the time wasn't the real culprit.
What do you mean?
Your father was framed?
Six more people were murdered in the same way.
While my father was in prison.
Why are you telling me this now?
The circumstances have changed.
Just now,
for the first time,
the killer left the body here.
The train is damaged,
and the passageway is closed.
(Mukyeong)
(Train)
(Episode 7)
It's the victim's phone.
- Okay. Call her family. - Got it.
(The woman)
Why does the victim have Inspector Han's number?
(Korean Language)
(Mukyeong Police Station)
(Case Summary)
(Initial witness: Han Seo Kyung)
How did this happen?
(Trustworthy Police, Safe Country)
Let's talk.
I explained everything already.
The victim Jo Young Ran is my father's second wife.
I called her after I found out Kim Jin Woo was targeting her.
I only lived with her until high school.
After that, we had no contact...
- and I know nothing about... - Wasn't it tough?
Living with that woman.
You must've heard...
what she was like while investigating Kim Jin Woo.
Whose fault was it that...
I lost my dad and had to live with her?
Did you never think of it?
The necklace Jo Young Ran was wearing is your mother's, isn't it?
One of the jewellery that disappeared from the crime scene 12 years ago.
Do you remember what I said?
That our beginning...
isn't as the murderer's son and the victim's daughter.
I said I'd prove it.
The real killer is someone else.
He kills people the same way he killed your father...
and leaves a piece of jewellery there that he took from your house.
That is his signature.
Lee Jin Sung was killed because he saw the real killer.
He's the one who took and killed Jung Kyung Hee.
Other than them,
there are more missing people that he killed.
I myself...
saw their bodies.
That serial disappearance or murder.
If you're on about that nonsense again...
Then what was a necklace that vanished 12 years ago...
doing at the crime scene?
The jerk who killed Jo Young Ran and left the necklace on her...
is the person who really killed your father.
The person Kim Jin Woo saw.
I don't know. I don't remember.
Tell the truth.
What did you see in the byway the day Jung Kyung Hee disappeared?
Anyway,
even if I saw something,
why should I tell you?
To do you good?
If you're right and my landlady...
was killed by Jo Young Ran's killer,
shouldn't I go and thank him?
I'm so resentful that I couldn't kill her myself.
It's time for my warrant evaluation.
If you have more to say, come to lock-up.
Jin Woo. Killing a person...
- isn't hard at all. - What?
Shall I show you?
A person can die from one blow in a split second.
A minute without air kills too.
30 more seconds like this and you're dead.
You crazy jerk.
Jin Woo, do you know what the biggest challenge in life is?
It's living with the responsibility of taking someone's life.
And I've done it.
I carried the bloodline of a murderer.
Once I'm dead...
as all of my blood runs dry, will my sin...
wash away?
I have been suffering in pain for a very long time.
I didn't...
want you to live in such pain.
You can continue to live in a world where you kill people.
Or you can live in a world where you save people.
The choice is yours...
starting this moment.
Why did you go to your father's cinerarium?
I could have come with you.
Did you bring what I asked you?
Why do you suddenly want to look into your father's case?
I saw the date on his urn.
Did he really pass away that day?
April 8, 2008?
(Time of death: Estimated between 9pm to 10pm on April 8, 2020)
It happened...
in front of that house that day.
(Kyeongmu-dong 528-2, Songin-Gu, Mukyeong City)
What?
I saw it.
The car.
Father?
Hey.
Two incidents took place at the same place,
at the same time, on the same day.
One is a murder. And the other one is a hit-and-run.
And both culprits weren't caught.
Could that...
be a coincidence?
The real culprit...
must have hit my dad while running away.
I must find that car, Jung Min.
You can continue to live in a world where you kill people.
Or you can live in a world where you save people.
The choice is yours...
starting this moment.
(Ilsuk Landscaping)
(Ministry of Justice)
Get on the bus. Darn it.
I checked the security footage at the gate...
of Jo Young Ran's house.
The storing device was destroyed.
I think Kim Jin Woo might have taken care of it beforehand.
There were no signs of forced entry.
But some workers entered the house because of the recent construction.
Did you look into Jo Young Ran?
Yes. Just like you said, she has a unique background.
Her late husband...
So, Inspector Han's dad left behind an insurance claim.
It was a large sum of money.
With the money, she made investments.
It seems she was a pretty good investor.
She got a fortune when the house he left behind got redeveloped.
So when she took an interest in that field,
she decided to make a career out of it.
Why didn't you ask Inspector Han yourself?
It won't be a good memory for her.
What about her son? She probably has a son.
Is he in an institution?
I talked to him on the phone. He's coming to the station.
- Hello? - I saw him.
- What? - I just saw him here.
The driver I saw at the shortcut.
(Ilsuk Landscaping)
The culprit who abducted Ms. Jung.
It's him.
There he comes. The victim's son.
I saw him. The driver in the black SUV.
We spoke on the phone. I'm Woo Jae Hyuk of Mukyeong Police.
I just saw him go into the police station.
He has a spot on the back...
of his left hand.
Danger, mirror, traffic lights, stop. A train comes.
Chug-chug, puff-puff.
It was me who killed.
(Autopsy Report)
(Cause of death: Asphyxiation from compression of the neck)
The cause of death is asphyxiation?
It wasn't the fractured skull?
I found petechiae on her eyelids.
And there was bleeding inside her throat.
After choking her to death,
the culprit struck her head.
The murder weapon was probably...
a blunt object with a 6cm to 7cm diameter.
The culprit swung from right to left.
So the culprit was right-handed.
I think the culprit strangled her with a thin chain.
You know, something like a necklace.
Did the culprit strangle her...
with this?
No, not this one.
Given the wound on her skin,
the chain should be as thick as 0.5cm.
It should be thicker than this.
I saw a pressure mark on her wrist.
I think it was bruised because someone grabbed her wrist hard.
But it was from the night of her murder.
She must have gotten it at least 3 to 4 days before the murder.
Excuse me.
(Dr. Seok Min Jun)
- Drink this. - Okay.
I stopped by to tell you about Dong Hyun's hypnotherapy.
Dong Hyun might have seen his dad when he was running away.
His defensive mechanism was probably triggered,
so he might have erased that from his memory.
Thank you for your help.
By the way, I think something is up with you.
Dr. Seok.
The woman is dead.
But the murderer could be the real culprit who killed my dad.
"The real culprit"?
If Seo Jae Chul wasn't the killer,
whom have I...
been resenting my whole life?
Is there anyone you have in mind?
I told you...
the woman came to see me a few days ago.
I'll pay it back. I said I will.
Once the papers are sorted out, I just need a few days. Wait.
Besides, don't call me until I call you. Got that?
You have a nice car.
Gosh. I can't even dream of having one with my paycheck.
Can I take a look?
Gosh, this is cool.
Was your leg injured?
I just sprained it a few days ago.
Why do you ask?
I'm suspecting your mother's murder to be a serial murder case.
I received a report from a witness that the culprit had hurt his leg.
So what about my leg injury?
I'm not saying anything about it.
Usually, the victims' families...
are curious about how the investigation is going.
Not that many people just leave after only answering our questions.
I'm just informing you.
It seems to me you are completely heartbroken about losing your mom.
Thanks for showing me the car.
I'll call you if we have any updates.
By the way, you seem like you'd drive a bigger car...
than a sedan.
For example,
a black SUV.
I promise I'll catch the culprit...
who killed your mother.
(Office of the Director of Detective Division)
(Director of Detective Division, Oh Mi Sook)
(Front Desk)
Mr. Seo Jae Chul. It's me, Oh Mi Sook.
Is no one inside?
Mr. Seo.
Mr. Seo!
Did you hear the autopsy result?
The cause of death was asphyxiation, not a skull fracture.
And I bet they also couldn't find...
any DNA, fingerprints, or trace evidence...
just like 12 years ago.
Do you still not believe me?
The nurse told me that you found a suspect...
that corresponds with Kim Jin Woo's statement.
Is that perhaps...
Lee Sung Wook?
A few days ago, I met that woman.
She kept calling me, but I didn't pick up.
And in the end, she came to the police station.
(The woman)
What do you want?
That's what you're going to say to your mother...
when we haven't met in years?
This is why they say it's never good to trust humans.
You were never my mother.
Come home.
At least for a few days.
Just do me a favour.
How could you ask me...
to live in that house?
I'm asking because I'm scared.
Whatever the case, you're still a cop.
I'm so scared...
of Sung Wook.
I just met Jo Young Ran's housekeeper.
Lee Sung Wook lost a lot of money by gambling and starting a business.
And since she stopped supporting him financially,
they weren't on good terms for the past few years.
Then that explains why he left her body in the house.
Her death needs to get registered...
in order for him to get his inheritance.
If Lee Sung Wook...
really did kill my dad like you keep telling me...
Then he probably has...
the rest of the jewellery.
Mr. Seo, I looked up the cars registered to Lee Sung Wook.
And it turns out he really does own the car you mentioned.
(We are against the redevelopment!)
I'm sorry. Are you okay?
- Yes. - I think you're severely injured.
- No, it's okay. - No, you should go to the hospital.
Hey, you're here.
- Have you been well? - Yes.
The car is too big.
Here.
Don't worry.
See you.
Wait.
If he really did commit a crime with that car,
there should be evidence on it.
- Inspector Han. - I'll find the car...
or search his house.
I need to check for myself...
and see if Lee Sung Wook really is the culprit.
What do you think you can do right now?
We only have circumstantial evidence.
And Kim Jin Woo's statement alone...
isn't good enough for us to get a search warrant.
Then do you suggest...
that we should sit back and wait for Lee Sung Wook...
to destroy evidence?
Yes, we need to wait until he tries to destroy evidence.
Who are you?
Police. Someone reported that they saw this car at a crime scene.
We'll take the car from here.
You can't just take it away. Do you have evidence?
Bring me a warrant.
The moment the owner gives up the car to be scrapped,
it's considered your property.
And because it's junk, we don't need a warrant for it.
You're not going to refuse to let us take it, right?
If we find any kind of evidence from that car,
you'll end up seeing me again.
By the way, you seem like you'd drive a bigger car...
than a sedan.
For example,
a black SUV.
I promise I'll catch the culprit...
who killed your mother.
Mr. Seo.
I have Lee Sung Wook's car.
Lee Ji Young?
(Lee Ji Young)
She's one of the victims.
You'll be able to find stuff regarding the other victims as well.
Once you get the DNA results,
compare them with the missing persons database.
- Yes, sir. - Got it, sir.
It looks like a key to a locker room.
I'll leave you everything in here, Seo Kyung.
It was Lee Sung Wook.
(Mukyeong Police Station)
The police...
are tracking a man who's suspected of...
killing his mother and taking and killing six others.
The suspect Lee is said to possibly be...
the culprit of the 12-year-old Mukyeong Residential Murder,
shocking the public.
People are criticizing the police's poor investigation in the past,
while the police are focusing their efforts on finding...
the bodies of the other victims.
Do Won.
You were right.
Eventually,
I have ruined...
your life.
Nothing is ruined, Ms. Oh.
We just took a detour.
My heart breaks when I think of my father,
but still,
I got lucky.
Beliefs, morality, justice.
Someone gave all that up...
to choose me.
No, Do Won. Do you want to live...
the rest of your life as a killer's son?
I'm grateful too.
I also found a reason.
A reason to live.
I had a reason to live instead of dying.
I lost everything.
But eventually, I got it all back.
That's why nothing is ruined.
And right now, all that...
is going back to its place.
Ms. Oh.
None of this was your fault, detective.
It's been a while...
since you called me that.
Did you...
find where my father is staying?
I'm still looking.
Okay.
Until Lee Sung Wook is locked up,
I'll need your help.
I must arrest him...
to put Father at ease.
Then we can apply for a retrial.
Can I ask you for a favour too, Do Won?
Arrest Lee Sung Wook as soon as possible.
(Director of Detective Division, Oh Mi Sook)
Is this why you came to see Do Won?
Because...
your time is near?
Please don't tell...
Do Won about this.
Please don't, Detective Oh.
I caused him pain all his life for being his father.
I don't want to...
be a burden to him as I die.
(Letter of Resignation)
By the way, about Inspector Han Seo Kyung.
Do you know...
who she is?
Yes. The daughter of Han Kyu Tae, the victim from 12 years ago.
Then...
did you think about...
why she joined your team?
(Mukyeong Police Station)
Mr. Seo.
We identified the victims.
We also found Jung Kyung Hee's DNA.
(Personal Details)
Lee Ji Young was the only person not reported missing.
We don't have an address either.
Her grandmother is in a nursing home, right?
Yes.
Her senile grandmother is her only family.
The victims' ages and occupations are all varied.
We don't know the reason they were targeted.
Meet their families and find out what they did the day they vanished.
Okay.
Where's Inspector Han?
Someone saw Lee Sung Wook.
The tip was a dead end, but she went to check anyway.
Hi, Jung Min.
Can you come over here?
What's up?
I finally get it.
Get what?
Mr. Seo.
His father spent over 10 years in prison for nothing.
That's why he was so out of his mind.
Because he was angry.
Wouldn't you feel the same?
Mr. Seo said that day that Jung Kyung Hee was dead.
How did he know that?
Is he psychic?
Stop talking such nonsense.
Aren't you supposed to help look for the victims?
Okay.
Will we find the victims' bodies?
Mr. Seo said that there's no way we'll find them...
You're a detective.
Get that.
Hello, Serious Crime Team Three Woo Jae Hyuk speaking.
What?
What is it?
The day I checked the scene.
I found bloodstains in Jo Young Ran's home.
- Blood? - Yes.
In another room, not the bedroom Jo Young Ran died in.
It was an old bloodstain.
I collected the DNA and put it through our database.
You know that the DNAs of field detectives are...
registered in the database, right?
Yes.
It was Inspector Han's bloodstain.
Inspector Han Seo Kyung on your team.
What are you talking about?
Didn't you say she lived in that house a long time ago?
I found a record of the dispatch at the patrol division.
(Kyeongmu-dong 21, Songin-Gu, Mukyeong City)
This isn't related to your case.
But I thought you should know.
(Restricted area, Do not enter)
Darn it.
If you come close to me again, I'm going to kill you that time.
Did you get that?
Or should I kill you now?
How will you fix my son's eye?
You made my son go blind!
How will you fix that? How?
Oh, no.
No, Seo Kyung.
(Korean Language)
(I'm going through all of this because of Seo Jae Chul...)
(who killed my father. I'm going to pay him back for this.)
Yes, I checked, but it was a false alarm.
Lee Sung Wook's cell phone was turned on?
Yes. It was on for a second.
But it's another bust. He turned it off after five minutes.
Where was he when he turned his cell phone on?
(Map of Mukyeong City)
(Kyeongmu-dong)
(Daemu-dong, Hwajin-dong)
Detective Kang.
It's about the traditional market Kim Jin Woo's grandma worked at.
Where was it?
Was it in Daemu-dong?
Yes, that's right. She worked at Daeyeong Traditional Market.
(Daeyeong Traditional Market)
It was you.
You were the cause of everything.
You killed Han Kyu Tae...
and hit my dad with the car.
I saw you 12 years ago...
in that alley.
No. It wasn't me.
I didn't do it. Not me.
I didn't do it.
It was you who killed.
Step on it. Just run him over.
No. I can't do it.
We killed your stepfather.
That man will tell the police.
You killed him. I didn't do it.
I killed him.
I did it. It was me.
I killed him.
I did it.
It was me.
(Pharmacy)
Who's there?
Hey.
(Mukyeong Police Station)
Why are you telling me that now?
(Serious Crime Team 3)
What's wrong?
Inspector Han asked me the location of the traditional market.
That place we went to do a background check on Kim Jin Woo.
The market that Jo Young Ran was trying to redevelop?
(Kyeongmu-dong)
That means Lee Sung Wook also knows about this place.
It's a great place for a hideout.
(Inspector Han Seo Kyung)
If Inspector Han went there by herself,
- should we call for backup? - The receiver cannot be reached.
No, don't. Follow me, and don't tell anyone.
Why doesn't he want backup?
I don't know. Let's go.
(We are against the redevelopment!)
You go that way. Joon Young, you go that way.
Hurry.
Look who's here. It's Han Seo Kyung who made me go blind.
Why did you do it?
Why did you kill my dad?
You were brave enough to come all the way here to ask me that,
so I guess I should tell you.
I didn't mean to kill him from the start.
I just went there to steal some jewellery.
But your dad came home earlier than expected.
It rained that day.
Your dad just got unlucky.
Your dad looked just like you...
while being strangled like this.
I should've cut your neck, not your eye.
Let me do the same to you.
Which eye should I stab?
Your right eye? Your left eye?
I don't know. Are you sure you can do it?
What?
Why do you think I came here alone?
So I could catch you by myself? No.
I came to kill you.
When I stayed alive even after I cut my wrist,
I decided to find the guy who messed up my life...
and killed my dad...
so I can repay him for everything.
I was determined to kill him.
I told myself...
to stay alive until then.
Seo Kyung.
Seo Kyung!
So all my life, I tried so hard to find Seo Jae Chul...
without even knowing that you were the culprit.
No. No, Seo Kyung.
I didn't kill him. I swear.
I didn't kill him!
I'm sorry.
I'm sorry I wasn't here.
I'm sorry I left you all alone.
I'm sorry.
(Daemu-dong)
(Seo Do Won)
(Public Official ID, Seo Do Won)
It's all over now.
I took revenge.
And my career is done.
What matters...
is that you're still alive.
I'll check over there.
Hello?
It's Seo Do Won from Serious Crime Team Three.
Lee Sung Wook isn't the killer.
There's an accomplice.
He's the real killer.
Hey.
The 12-year-old case and what happened after.
It was all his doing.
Are you...
Listen carefully.
Lee Sung Wook is an accessory.
The murderer is someone else.
You must get Lee Sung Wook and make him confess...
who the killer is.
(Train)
I'm back in my world.
I wondered where you'd gone while I was in your world.
I didn't know we had swapped places.
Why do you think it's "fate"?
It's called that because it's unavoidable.
- By after-effect you mean... - An intellectual disability.
He'll have the intelligence of a young child.
I'll try not to disappoint you again.
When all this is over, let's start afresh.
I'm sorry. I wanted you to...
die a painful death.
It's you. The reason he won't leave.
