We're here at Mukyeong Station, where a skeleton was found.
So far, they've found a total of four skeletons.
Did you check the security cameras?
This place has been closed down for a long time, so there's nothing.
It's been undergoing redevelopment for years, so there are no cameras.
12 years ago, there was a case with a similar MO.
The Mukyeong Residential Murder.
He was the one who killed your father 12 years ago.
My father did it.
Say you're sorry.
You know that you shouldn't tell such a lie,
Tell me you're sorry.
He has the intelligence of a preschooler.
He managed to kill people in secret and buried them?
And he killed four people?
The Mukyeong Station bodies. My son didn't do it.
The first person to find the body in a bag was me.
How did these earrings...
This company went bankrupt eight years ago.
The company that took over didn't manufacture this at all.
How can the fingerprints...
of a dead person be found on a cup that was thrown away two days ago?
Hello, I'm Lee Ji Young.
"2020"?
(Previously)
No way.
Seo Kyung!
(2008)
Never! I won't do it again.
I promise you. No, I swear!
If you lay a finger on her again, I'll kill you.
I'll kill you and your mom!
If I have to.
If you get what I mean, you'd better not show up again.
Let's go.
I fixed a few things for now.
It won't be as comfortable as your old place.
We can fix the rest after you settle in...
By the way...
Thank you for what you did at the station that day.
For saving me.
I want to thank you too.
I found...
a reason.
To live.
You won't ever get hurt again.
I promise.
Seo Kyung.
Seo Kyung!

(Chapel of Rest)
Seo Do Won. It's not true, right?
I misheard, didn't I?
It's nonsense, isn't it?
Why is Seo Kyung here?
What happened?
Seo Kyung...
(Chapel of Rest)
Do Won.
Mr. Seo.
Do Won.
Jung Min.
Wake me up.
Please.
(Police)
What's this? That's a gunshot wound.

- Anything for the press? - Did you catch the culprit?
- There she is! - Please answer our questions.
- Do you have a suspect? - Is it true?
(Han Seo Kyung)
(Our deepest condolences, Classmates from Judicial Institute)
Mr. Seo.
Right before Ms. Han was murdered,
she called you.
Did you talk to her?
(You have a voice message.)
You have one new voice message.
Do Won.
It wasn't your father.
You said then that you liked me.
That's why I went away.
It wasn't your father. It was him.
It was the culprit of the Mukyeong Station Case.
He killed...
my father.
It was my father.
He was the one who killed your father 12 years ago.
Do you really not get what I'm telling you?
The reason I stayed with you.
And the reason I had to leave you.
This is the real reason behind that.
I always...
felt like I was indebted to you.
I always felt so guilty.
And I always...
wanted to break free from that.
So just leave me alone.
I beg you.
All of my mother's jewelry...
disappeared 12 years ago.
The victims of the Mukyeong Station Case...
were wearing them.
All five of them.
I wanted to share this with you once I was completely certain.
Do Won.
You don't have to...
feel guilty now.
You must have had a hard time because of me.
I am sorry...
that I liked you.
(Prosecutor Han Seo Kyung)
What are you doing here?
I was just thinking.
When I hear a sound from outside,
I know it's not her,
but it still startles me...
because I almost think Seo Kyung might walk in here.
She probably felt the same way...
every single night here all alone...
after I left.
That night,
I heard everything you told Seo Kyung in the warehouse...
at Mukyeong Station.
- About your father. - Jung Min.
It wasn't my father.
What?
12 years ago,
this jewelry went missing from Seo Kyung's house.
And the victims...
of the Mukyeong Station Case were wearing them.
Does it mean...
it's the same culprit?
The culprit who killed Seo Kyung's dad...
killed her too?
I have been going about this the wrong way from the get-go.
12 years ago,
my dad was just unlucky.
He was in the wrong place at the wrong time.
It was probably after...
Seo Kyung's father was murdered.
If...
my father hadn't been in an accident that night,
would things have changed?
What if Seo Kyung and I never met?
Would Seo Kyung...
still be alive now?
I will not forgive him.
I found this in Seo Kyung's body.
It's from a 38-caliber revolver.
It's the same gun the police use.
Do whatever it takes to catch him.
Catch the culprit that killed Seo Kyung...
no matter what.
I failed to catch the culprit of the Mukyeong Residential Murder...
12 years ago.
If the culprit of this case...
really turns out to be the same person,
that would mean I'm the person responsible...
for the victims' deaths.
Right now, anyone who replaces me will only be forced...
to take responsibility.
Once I solve this case,
I will step down from my position.
We're guessing the sixth victim was in her 50s.
The victim was a woman, and she died just like the previous victims.
The culprit strangled her to death...
and used a weapon to strike her head.
Also, her fingerprints were chemically erased,
so we cannot identify who she is.
If you look here, we detected a certain type of dye...
that's used to make car seats on her fingers.
We're trying to identify who she is by checking the relevant factories.
One thing you need to know...
is that the victim wasn't wearing any of the jewelry...
that was stolen 12 years ago.
Did you identify the fingerprint that was found on the flyer?
We detected three fingerprints from the right hand...
on the flyer found in the bag.
We found that one of them was a thumbprint,
and the other two were the index and middle fingers.
What's the update on Lee Ji Young, the fifth victim?
Well...
This is absurd.
No one ever told me...
that I had a twin.
Right now, that's the only assumption we can make.
You told me you never met your biological mother, right?
The hospital you were born in burned down due to a fire,
so we couldn't check your birth record.
Twins normally don't have the same fingerprints.
But there was once a case where all three triplets...
were born with the exact same fingerprints.
Then why isn't there anything about her?
She should at least have an ID or something.
The biggest possibility is that she stayed here illegally...
because she was adopted overseas right after she was born.
Okay.
I'll take over the body then.
Ms. Lee, when did you get that burn mark on your neck?
My grandma told me that I spilled coffee on my neck...
when I was five years old.
I spilled it all over my shoulders too.
She was relieved that I didn't burn my face.
Okay. Thank you.
Mr. Seo, we have the fingerprint identification results.
I'll send it to you right now.
(Mukyeong Hospital)
Mr. Seo, do you remember this guy, Lee Jin Sung?
Remember the huge drug scandal from three years ago...
that exposed the serious drug abuse by children from rich families?
It happened because this guy was keeping a file.
They're definitely Lee Jin Sung's fingerprints.
But isn't it weird?
Just like 12 years ago,
the culprit didn't leave behind a single trace.
He can't be clumsy enough to leave his fingerprints like this.
(Name: Lee Jin Sung)
Did you check where he lives?
He got out of prison at the beginning of the year.
We don't know where he lives now.
What about Park Min Kyung?
She's 29 years old.
She was his girlfriend when he got arrested.
Do you know this guy?
I was the one who arrested Lee Jin Sung.
May I help you?
Park Min Kyung works here, doesn't she? Where is she?
"Park Min Kyung"?
Who's that?
(A Reum)
Hey, what's...
Detective.
I broke up with him when he was in jail.
It's been a while since I last heard about him.
I really don't know where he lives or what he's up to these days.
Lee Jin Sung, I know you kept a record...
of the transactions you made with your VIP clients.
Where is the ledger?
I don't have a ledger.
The person in charge already told me everything.
We were even given evidence.
Do you really want to take responsibility for everything?
(Interrogation in progress, Authorized personnel only)
You were the one who had this?
Will you make sure he gets a lower sentence?
I know him well. He's going to have a hard time adjusting to prison.
Didn't you get that hairpin from Lee Jin Sung?
Which question do you want to answer first?
Where are you going? And whom are you going with?
Go. Leave.
- Darn it. - Mr. Seo!
Move!
Hey, stop!
Mr. Seo.
Darn it.
Go away!
- What are you doing? - Four days ago.
Where were you, and what were you doing?
What else?
I was working.
Stop joking with me, and tell me the truth.
Will you please get rid of the gun first?
- Mr. Seo. - Mr. Seo.
We checked his alibi.
We checked the surveillance cameras.
And he was at work all afternoon.
Mr. Seo, calm down.
Then why did you run?
What's with the passport?
Why were you trying to leave the country?
How do you expect me to live here?
This kind of stuff happens every other day.
It's already embarrassing...
that I can't get a job anywhere else other than Min Kyung's workplace.
I was sick and tired of this life,
so I was going to move to Canada with her.
My entire family lives there.
Plus, that's where I used to live.
How long did you live in Canada?
I went there when I was in elementary school,
and I lived there until I turned 20.
My gosh. Come on.
I never should've come back here.
Lee Jin Sung was 20 in 2010.
12 years ago, he was not here.
Will you please stop it?
- Are you okay? - Honey.
My gosh.
Then how do we explain the fingerprints?
Mr. Lee, do you know what this is?
- What is it? - The fingerprints...
of your right hand were found on it.
Some men came to see him as soon as he got out.
I bet they were sent by the people on that ledger.
Ever since that day,
he never takes off this glove even when he sleeps.
Because that memory is so dreadful.
And now you use that to drag him into this?
Is this the price of cooperating with the police?
They were prints from his right index finger.
What's happening?
What is going on here?
Mr. Seo.
(Mukyeong Police Station)
Where is Mr. Seo?
I can't reach him.
Send him to me as soon as he comes in.
What should we do about Lee Jin Sung's fingerprint?
Reconfirm with Forensics.
See if there was a mistake.
(Oh Mi Sook)
Yes, ma'am.
(Director of Detective Division)
It wasn't Do Won's father, Ms. Oh.
- What? - There's someone else.
That person killed my dad...
and abandoned the bodies...
at Mukyeong Station.
What do you mean?
I'll let you know once I'm sure of everything.
(Mukyeong Church)
(This week's events)
(Mukyeong Church)
Hello.
Police released the identity of a suspect...
and issued an APB for shooting Lee,
a drug broker in the head, killing him.
According to the police,
the suspect, Senior Inspector Seo Do Won,
is on the run and works at...
Mukyeong Police Station.
The public is reeling in shock.
Police are still tracking Senior Inspector Seo Do Won,
and hope to find him.
The public voice their fear and unrest...
that a serving officer was involved in a crime.

(True Wheat Church)
Okay! I'm coming!
Who are you? How can I help?
We moved here a long time ago.
Has it been five years now?
We changed the church's name then too.
Will you take a closer look?
Did you mistakenly put in...
the wrong name or address?
That has never happened before.
(Mukyeong Church)
We didn't issue this.
We didn't host an event like this last year...
Hang on.
This is a bit weird.
(This week's events)
This is our previous pastor.
Where is he now?
Where can I go to meet him?
He died of cancer three years ago.
(Pastor Park Young Tae)
Are you all right?
What? He shot at Lee Jin Sung?
Yes.
Gosh, Do Won...
Where is he now?
I don't know. He's not answering his phone.
What did Ms. Oh say?
She's furious and wants us to...
get him immediately.
But I don't think this is something...
Ms. Oh can sort out.
This is just insane.
By the way, Lee Jin Sung's prints.
Are you sure they're from his right hand?
Follow me.
Se Hwan, pull up AFIS.
On the left is Lee Jin Sung's print that's in the database.
On the right is what we found this time.
The fingerprints...
on the bag and flyer were definitely Lee Jin Sung's.
Okay.
We had a huge fuss with Lee Ji Young.
Now I'm afraid when we just find fingerprints.
I'll get going. See you.
He died of cancer three years ago.
(Jung Min)
- Hey. - Are you out of your mind?
Do you want to get arrested before you catch the guy?
Was Lee Ji Young really a twin?
- What? - The clothes. Do you remember them?
The clothes found with the skeleton.
This company went bankrupt eight years ago.
And another company acquired this company.
And the name of the brand changed completely eight years ago.
This was manufactured last year.
Don't change the subject and answer me.
Where are you right now?
(Mukyeong Station)
(Ms. Oh)
Do Won.
You came here after causing that big mess?
Seo Kyung was shot over there.
Based on the analysis from the NFS, the bullet was fired...
right behind Seo Kyung.
And the bullet was fired from a height of around 2m 10cm.
- What? - But there's nothing here.
What did the culprit step on?
Have you heard of a ghost train?
About 100 years ago, in Europe,
a train on the tracks vanished into thin air.
The train that disappeared was sighted...
for the next 100 years all over Europe.
All the witnesses said the same thing.
"A mysterious train showed up..."
"on empty tracks in the dark out of the blue."
What are you talking about?
Jung Min, if you told me that you saw a ghost train,
- would I have believed you? - What?
If I told you that I saw the train here,
would you believe me?
If I said something absurd...
like the culprit who killed Seo Kyung could have been...
on that train, would you believe me?
Do you think I'm going mad?
Or are incidents that can't be explained...
taking place here?
What was that all about?
You were joking, right?
There's one more person...
who saw the train besides me.
(Happy Correction and Harmony)
The inmate you requested needs absolute rest.
Only his family can visit him.
It was his doctor's order.
I'm sorry.
Hello?
Yes. I see. Yes.
Yes. The warden left 30 minutes ago.
Yes.
I'll look into that. Yes.
(Sane Mind and Happy Society)
You saw it, didn't you?
You saw her before!
When and how did you first meet?
A train. A train comes.
Chug-chug, puff-puff. Chug-chug, puff-puff.
I know you saw that train.
He was on that train, right?
Didn't he abandon the bodies there?
It was me.
You were locked up...
- on the day when Seo Kyung died. - What are you doing?
- Get off him. - Stop it.
Tell me. You saw him, didn't you?
Wait. Let go.
- Answer me! - Get out of here.
It was me.
It was me who killed.
- Answer me! - Get out of here.
It was me.
It was me who killed.
This is an announcement for the passengers.
- Due to an inspection of the train, - It's around the corner.
- the train that was supposed to... - Just hang in there a bit more.
depart at 10:30pm to Mukyeong Station will be delayed.
We apologize for any inconvenience.
What?
The train is about to depart. Please get on board.
- Darn it. - The train in Platform Three...
is number 1426.
The train Mr. Seo got on is departing now.
Excuse me.
Wait.
Mom, are you not done yet?
Hurry.
I told you to stay in your seat.
Mom, I thought you were in the restroom.
Jung Min.
What brings you here?
I have something to tell you.
It's about Do Won.
Hello.
What's this?
What is this about, ma'am?
(Mukyeong Residential Murder)
Find out what he's been taking.
Okay.
It's an analeptic.
It's a stimulant.
Go and get Mr. Seo now.
Track his phone or put an APB on him.
Take his ID, his cuffs,
and his gun.
Do it now.
Should I do it?
Yes, ma'am.
I want you off the case, Mr. Seo.
The team leader from Team Two will take over.
Ms. Oh.
Detective Woo.
- Yes, ma'am? - You were with him yesterday.
Was it really necessary for him to fire live ammunition?
I want an answer. It's an order.
Was it the appropriate thing to do?
No, it wasn't appropriate, ma'am.
A disciplinary committee will be held soon.
You will be suspended until then.
I refuse.
I refuse to abide by your orders...
until I catch the culprit.
Is this what you call treatment?
You're so addicted to these drugs...
that you can't even tell what's real and what's fake.
You're not doing this for Seo Kyung.
You're only destroying yourself and running away.
Even if you catch the culprit...
Even if...
you kill that culprit,
Seo Kyung will never come back.
Then...
What am I supposed to do now?
What should I do?
What you need to do...
is to drop what you've been doing...
and slowly start accepting reality.
The drug we saw earlier...
Isn't that what Mr. Seo always takes?
Did you know it was a stimulant?
If I knew, I would've told Ms. Oh myself.
But still, it isn't an illegal drug.
Tons of homicide detectives...
take drugs to get by.
The drug isn't the problem.
You know what this is about.
It's true that we all risk our lives doing this job.
But Mr. Seo is way past that line.
My gosh. And truth be told, that's what I liked about him.
Me too.
Anyway,
it's too dangerous to let him continue.
- Sir. - What?
The gun... Mr. Seo's gun is gone.
Is this what you call treatment?
You're so addicted to these drugs...
that you can't even tell what's real and what's fake.
You're not doing this for Seo Kyung.
You're only destroying yourself and running away.
Even if you catch the culprit...
Even if...
you kill that culprit,
Seo Kyung will...
never come back.
Seo Kyung.
Do you really think I'm crazy?
But what's the use?
You're no longer here.
We checked all the passengers before arriving at Mukyeong Station,
but he's not here.
My gosh.
Do you think he saw us earlier and got off?
This is the police.
If there's anyone inside, can you please respond?
Police. Open up.
Hey! Go after him!
(Seo Kyung)
Do Won.
I wanted to share this with you once I was completely certain.
You must have had a hard time...
because of me.
I am sorry...
that I liked you.
But Do Won.
I was happy to have met you.
You made me happy.
Even if I were to experience all of this again,
I'd still...
want to meet you again.
- Seo Kyung. - Please stay in your seats!
We're the police.
- I'm sorry! - Stay seated!
- Sit down! - Stay in your seats!
- What's going on? - Hey, watch it!
- Sit down! - That darn punk.
Out of the way! Stay in your seats!
Get over here!
Stay in your seats!
This stop is Mukyeong Station,
the final destination of this train.
- Please remain seated... - Seo Kyung.
until the train arrives...
at the station.
Drop your gun!
You're under arrest for killing Lee Jin Sung!
Drop your gun and raise your hands.
If you don't cooperate, we'll shoot.
What station are you with?
What do you mean Lee Jin Sung is dead?
Drop the gun! Stay where you are!
Seo Do Won!
The suspect is fleeing on foot!
He's armed! He has a gun!
(Mukyeong Station)
What is this place?
Where am I?
(Mukyeong Church)
Brother, come to Mukyeong Church.
(Mukyeong Church)
Do you not feel well?
He died of cancer three years ago.
(Train)
In this world, there's another me.
I'm ashamed that someone like you is a fellow police officer.
The incident from 12 years ago happened exactly the same way here.
You're still the most likely suspect.
Did you ever think about this?
That perhaps, somewhere else, we all live a different life...
with different relationships...
in another world?
I'm sure of one thing.
Wherever and however we met,
we wouldn't be on good terms.
