Unit One (2000) s01e01 Episode Script

Request for Assistance
A-15/99
Hi.
Torben!
- Look who's here.
- Back early?
We had to give up.
We were always going to be
troubled by a crafty killer.
- And we just met one.
- He's talking shit.
- We got a full confession.
- Bravo.
The case didn't get going
till I arrived.
- Impressive work as usual.
- Cut out the praise, Ulf.
- Torben's full of it.
- Or deluded?
Why not go
polish your nails?
Who'd fix up your mess then?
Ulf!
Where's that cheap bubbly?
The soccer's on soon.
- Your wife never sees you.
- She loves me watching soccer.
- Some marriage, Fischer!
- I agree. See you.
- Want a drink?
- I have an interrogation.
Now?
- Jesper Olesen's been busy.
- Targeting our best people?
He was offered heroin
and asked for a sample.
The politicians want us
to box his ears.
- It may be more complicated.
- Don't exaggerate.
She gets full marks
for persistence as usual.
Yes, and for the best arse
on the force.
Questioning of
Detective Inspector Jesper Olesen
19:32, Thursday June 17
I'm really sorry.
I forgot the time.
I ran into a soccer match.
Look here.
I've recorded the events.
I called your boss
and he recommended
I should do my own report.
Just check the grammar
and I'll sign it.
- So I get to catch the match.
- Let's take it from the top.
Sit down.
It's June 17 at 19.33.
Present are DI Jesper Olesen
and Deputy Detective
Commissioner Ingrid Dahl.
I had an offer of 14 kilos
and asked for a sample.
I called the unit
who arrived and seized the lot.
I know I broke the rules
by asking to see it
and I'm complicit in a crime,
blah, blah
But if I hadn't done it
we wouldn't have found the shit.
- Are we done?
- We'll be done when I say so.
Hey, Monty.
- Back home, Torben?
- For now at least.
Come on, Monty.
During the 18 months
you've worked as an agent
we've made four seizures
after your tip-offs.
I'm getting a medal?
Who's your informant?
- They tell me it's Birko.
- So why ask?
- So who's informing him?
- Why are we wasting our time?
The unit says
he's a big dealer so
when he tips you off
you're getting rid
of his competition.
In my time in the field we've
seized more junk than ever.
- We don't deal with criminals.
- All the time, sweetie!
It's quid pro quo,
and now we know
that Birko's the only one left.
Lately
you've executed two raids.
- Without finding anything!
- Change of luck.
One might suspect
that he was tipped off.
Darling, I'm off
to watch the football.
Weren't you recently
in London with your girlfriend?
- Was it a good trip?
- Yes.
Fucking day and night.
Ever tried it?
You flew business class
and stayed at the Savoy.
- So what?
- Here's your bank statement.
With big transfers
from her account.
- She's a generous girl.
- She works in a store.
Her statement
shows big deposits from
one of Birko's companies.
She consulted for them.
Bugger-all to do with me.
And you've never talked
by phone to Birko?
- For the tape, please.
- Yes, that's correct.
Please explain
these telephone calls
from your mobile to his.
Two dates, both after the unit
decided to raid him.
He's your informant
and you're his.
Plus which,
he paid you for it.
- Anything you want to add?
- Yes.
Up yours!
Monty!
Come here.
Were you visiting Torben?
Did you miss him that much?
UNIT ONE
The public prosecutor told me.
I felt so small,
ignorant that my own staff
were investigating
Episode 1
I'd appreciate being told.
Beforehand!
- I tried.
- Not to my satisfaction.
You were busy
with the Haderslev case.
If we can't communicate between
ourselves, what then?
I agree.
And we can talk about it if
Ulf Thomsen.
Lysberg?
What can I do for you?
What are you saying?
How?
I'll come at once.
Ulf?
What's happening?
Home of the murder victim
23:10, Thursday June 17
- Hello, Ulf.
- Hi.
- Question everyone nearby.
- It's being done.
Ulf.
They're not finished.
You can't come in.
- You know who I am?
- Yes.
- You can't come in yet.
- Listen, Nielsen
Torben was my deputy
and a friend for 25 years.
But take off your shoes.
- Do we know who he is?
- Not yet.
Ulf, I'd like your help
of course.
No need to ask.
You've got it.
Torben's own team
will come up here.
What should we make
of the other one?
Meaning?
I mean, I didn't know Torben
as well as you did.
If those cryptic remarks
allude to a homosexual motive,
you can forget it.
What's wrong?
Torben was killed at his home
this evening.
- No.
- I must get the others.
We'll go up there at once.
- Will you be in charge?
- I don't know.
- It would make sense.
- Kirsten, honestly
I'm sorry. Darling!
I'm very sorry.
Crime scene,
02:15, Friday June 18
We've checked all the houses.
No one saw anything unusual.
Most were watching the match.
- What did you ask? You are?
- Claus.
You asked if they'd seen
anything unusual?
Where did you train?
They say what they saw.
We decide if it's unusual.
You know what you do now?
You go back and ask them again.
I'll do it myself.
Thanks, Claus.
Remember to give me all reports
before you leave.
Yes.
Postcard from your dad.
From the beach.
- I'm ready.
- I just tucked you in.
- I can't be bothered sleeping.
- You've been up all night.
- Why were you up?
- I was marking essays.
I've now earned my holiday.
Anne from my class
is also going to Norway.
- You might meet.
- Not interested.
- Your bag
- It's the last day of school.
- Let's go mountain climbing.
- But keep that on.
- Fine with me.
- No, go to bed.
I'm going to work.
Read the paper.
What is it?
Murdered with friend
Office of the chief of police
08:45, Friday June 18
- Who was the other man?
- Henning Ravn.
A doctor.
A bachelor who'd been staying
at Torben's.
- We don't know why.
- And your opinion on that?
It's absurd. It reads as if
they killed each other
out of homosexual jealousy.
If that were the case
one would have had
to swallow the knife.
Any next of kin?
What, then?
Remember Bruno Gravesen?
A convicted murderer
of eight years ago.
Very violent.
Fatally so.
Torben cracked him.
He threatened to kill Torben
when he got out.
- He got out two weeks ago.
- Interesting.
His girlfriend hasn't seen him.
We've got the whole machinery
up and running.
Have you thought about
Torben's successor?
The most natural would be IP,
his second-in-command.
As a stopgap
till we find a younger man.
There's another possibility.
- Your Special Cases chief.
- Ingrid Dahl?
Smoke?
Thanks.
The public prosecutor praised
her investigation of Olesen.
- She's absolutely capable.
- And you trained her.
But as chief of Homicide?
No woman has ever had that job.
Don't misunderstand me, but
She'd be away from home a lot
and she has small children.
- He's eleven!
- If he gets the measles
- Would we close shop?
- And she has a husband.
This is not the time
for experiments.
She's worked
in Homicide before
and got top marks all round.
With all respect
for macho habitual thinking
I find it difficult to see
how you can overlook her.
Right?
It can't be true!
People just don't disappear.
After all, this is Denmark.
Lean harder on the girlfriend.
I'm sure she knows where he is.
Fine. Call me. Okay.
Haven't you found Bruno yet?
A pair of lovely boys, eh?
The FBI Course in 1995.
Torben was the best.
I feared they'd keep him.
I'll spare you
my sentimental chatter.
- Who is she?
- That's Signe.
- Torben's daughter.
- I didn't know about her.
She moved to England.
Gaby's looking for her.
Well
I've come to a decision.
Would you consider
leading the investigation?
Acting chief of Homicide
as of today.
- Am I not making myself clear?
- Yes, absolutely.
- What about IP?
- Meaning?
- Has he been told?
- Of course.
- Is he in agreement?
- I didn't ask him.
I bypassed 300 men
when I became commissioner.
I wasn't very popular.
You'll have to earn that first.
It's taxing.
Taxing on one's family life, on
holidays, public holidays,
evenings
Better be prepared for that
or say no.
Should I?
- What?
- I suspect that
you're trying to frighten me off.
That's precisely what
I can't abide about you.
- I'm sorry.
- I'm being realistic.
I know the realities.
- And I accept.
- Fine.
And
How I vote
on your final appointment
depends totally
on how you manage this.
- Fair enough.
- And I'll be properly informed?
- Yes, of course.
- Fine. That's all.
Go and find him for me.
I want to tell you something.
I've been put in charge
of the investigation.
It could cause us problems
with the holiday.
We'll talk when I get home.
Bye, darling.
Hillerod Police Station
11:15, June 18
Where do I find Unit One?
- What's it about?
- Down in the basement.
The basement?
- Are you lost?
- Hi, Fischer.
- Yes. What now?
- Here's the report.
We need three copies.
Can you find the time?
Shall I show you
to our luxurious rooms?
But she's lied to us once.
What's Bruno doing in Jutland?
This is it.
- Impressive?
- Hi, Gaby.
He got the computers
going in two hours.
- Not like the shop in Haderslev.
- That was Torben's style.
- Hi, IP.
- Hi, Ingrid. Welcome.
Thanks.
Shall we start?
- We started last night.
- Yes, of course.
Where are we with Bruno?
His girlfriend has admitted
he came to see her.
- After he got out.
- A fortnight ago?
She doesn't know why
he went to Jutland.
She got scared when she knew
why we were looking for him.
That could be all she knows.
- You think he's our man?
- Yes. The best bet.
Motive - revenge.
Any other possibilities?
Male prostitute?
- Is that a joke?
- It's a possibility.
- Just drop it.
- Two men living together
- Stabbed. One in his bed.
- Torben
Yes. Did you know him well?
Did he say he had
a friend staying?
A divorcee, like Torben,
whose house was being done up.
Know what he said
in every new town?
- No.
- He said
"New town, new pussy."
But did you ever see him
do anything about it?
So take some men
from the local squad
and check every gay bar
from here to Copenhagen.
- Seriously?
- I want to know if Torben
and Henning Ravn
were known there.
Ingrid's right.
Of course it has to be checked.
I'm off to see LaCour.
- You've worked with her before?
- Yes.
And now she's almost
commissioner
Fast mover
What about moving
a bit fast yourself?
Crime Scene
14:35, Friday June 18
- Hi, LaCour.
- Hello.
Got any ideas?
None.
I've been over it
again and again
but I can't find any logic
to all this.
You've been here all night?
Forensics says Torben and Ravn
sat here, watching TV.
Henning Ravn goes to bed.
Torben answers the door
and brings the killer in here.
He's stabbed there at first.
He flees in here
where he is stabbed twice.
Henning Ravn wakes up
and comes in.
Thinking Torben was alone,
the killer panics.
He stabs Henning
who runs into the bedroom
where the killer finishes him off.
But
would Torben
have invited Bruno in here?
Who had threatened his life?
And be taken by surprise?
Torben was very fit.
Tell me about him.
He was
He was one of the best cops
I've ever known.
But he never invited me
into his home.
Ingrid.
Yes.
Let me have it in writing
very soon.
Thanks.
Forensics says both men
had alcohol in their blood.
Torben and Ulf were
drinking champagne.
- How much did he drink?
- Enough to take a taxi.
He might have been a bit drunk,
and tired after Haderslev.
- Reason enough for sloppiness?
- Perhaps.
Torben was fixated
that details
were the key to the exact
moment of the crime.
- Follow that sequence
- LaCour, you're exhausted.
Do me a favour.
Go home and sleep.
Oh, yes.
We found this.
It's Torben's.
His daughter's address is there.
She may have moved to Ireland.
The number's crossed out.
See what you can do.
- That was Aalborg
- Bruno?
He used his mobile.
Two different signals.
A week ago
We'll check his acquaintances.
We have a confession.
He's upstairs.
The policeman called me.
When I arrived I saw
there were two of them.
That was all right.
I told them
it would cost a bit more.
They said it was okay.
I sucked one guy's dick
while the other buggered me.
Afterwards they refused to pay
and they threatened me.
And then?
I
I shot them.
Victor
Why did you turn yourself in?
- They told me to.
- Who did?
The voices.
If you confessed,
you'd be forgiven?
Yes.
Fine, Victor.
You're forgiven.
Go home.
Thanks.
You're Ingrid?
Chief Constable Hans Lysberg.
Welcome. Please tell us
if we can help with anything.
If you could keep
the worst nutters at bay
We located some
of Bruno's friends in Aalborg
but they weren't home.
We're still watching them.
I've found Torben's daughter.
Will you, or shall I?
You're talking to Ingrid Dahl
from Unit One.
I'm a colleague of your dad's.
I've got some very sad news.
Hello?
What's up?
The phones are playing up.
Have them fixed!
I'm in the middle of
Signe?
Our phones are out of order.
Yes. He's dead.
Last night.
Signe?
Is someone with you?
It's Torben's daughter.
- Get any tempting offers?
- Of course.
A shame
I was so damned tired.
- How are things?
- Like shit.
Bruno?
How did she take it?
- What did you find out?
- A waste of time.
No one in the gay bars
knows Torben or Henning.
Henning was Signe's godfather,
and straight.
She told me
he was a real womaniser.
We're wasting time.
Nothing's happening.
What else?
- Ingrid? Any suggestions?
- Yes, get some sleep.
- Like hell I will.
- Good night, Fischer.
- Let me just
- We need you fresh tomorrow.
- Yes, okay. Good night.
- Good night.
Drinks?
- Coffee, please.
- IP?
- May I say something?
- Yes.
Fischer should have stayed.
- But he was dog-tired.
- He should have stayed.
None of us can sleep anyway.
Interpol's found Bruno.
In a prison in Rotterdam
He's not our man.
He's been there for a week.
Let's call it a day.
- Thanks for today.
- You're welcome. IP
Thanks for your cooperation.
- I know you had counted on
- It's ten years too late.
You've always wanted
the job, right?
- How did you know?
- I've kept an eye on you.
- Would Torben have nailed this?
- It's only been 24 hours.
His last case took three weeks.
You're doing well.
- Thanks for your support.
- See you.
A toast to Denmark's first
female chief of Homicide.
Only if I solve this case.
And that doesn't look like it.
- Old Ulf is sweet on you.
- It has nothing to do with him.
I'm sure the chief of police
had some influence.
So you're happy with things?
I want the job for my merits,
not my sex.
I chose you
because of your sex.
Is this about
getting Dad's approval?
Don't analyse me.
What about the holiday?
- It's off. I've told Tobias.
- What did he say?
- What do you think?
- It's okay, Mum.
You can't go away
while a cop killer's free.
Come here.
I'm on the computer
- Congratulations.
- Thanks.
- I was lucky with him.
- May I say something here?
What?
You're very good at your work.
But?
You're no good at reading
your son's signals.
- He was very upset about it.
- He wasn't.
He has to be the big,
grown-up son for his mum, right?
- Now you're upsetting me.
- I don't mean to.
- We were alone for a long time.
- It's not that bad.
- Should I back out at work?
- No, no.
Shouldn't I go on holiday
with him?
Yes.
- I could take my daughter too.
- Good idea.
- You're so sweet.
- No, I'm an egoist.
My hiking boots need
to scale a mountain.
And that's okay with you?
- Taking what they dish out?
- You're probably right.
You won't even argue.
Should I have told Ulf
"I want that job"?
What an interesting change.
- And resigned if he'd said no?
- Yes.
That's what they deserve.
What would we live off?
Your bit roles at the theatre?
A divorce?
- And you let a youngster
- She's good.
- You'd like a female boss.
- I'm used to it from home.
petrol station at 21.39
- Good morning.
- Morning.
What if we were wrong
from the start?
What if this is not about Torben
but about Henning Ravn?
Here's Torben's lounge room
and the bedroom.
Torben was found here
and Henning here.
We've assumed that Torben
was killed before Henning.
What if Henning was killed
before Torben
and Henning was the target?
Torben came home and was
taken by surprise and stabbed.
- Interesting, but impossible.
- Why?
Forensics has Torben
drinking beer in the lounge.
I thought so, till I saw this.
Torben went to a petrol station
to buy cigarettes at half-time.
He wasn't in the house
for some 20 minutes.
Maybe Henning had a visitor.
Guess what genius wrote
a report without telling us.
Relax. No more killings!
- The motive?
- Don't know.
- Henning's details?
- Single doctor, lots of women.
And Torben's daughter said
Henning had a longer-term affair.
- A local.
- Ida Friis.
Ida Friis?
I'll locate her.
Ingrid.
Hi, Lysberg.
We've arrested
someone on another charge.
He has something of interest.
He'll only talk to the chief.
I know
But you should hear him out.
- I wanted the chief.
- That's me. What have you got?
Not with him present.
- I know about the murders.
- I'm listening.
Yes
But it will cost you.
I had some priors
before they nabbed me.
- Prisons piss me off.
- That's the whole idea.
A cop with a sense of humour!
I know who did it, why he did it
and how he did it.
If so,
you're obliged to tell us.
- I know nothing.
- We're in Denmark, not the US.
We don't do deals with criminals
regarding reduced sentences.
Where were the corpses?
One in the bedroom
and the cop in the lounge.
I'll call you later.
Ida Friis committed suicide
a fortnight ago.
I'm looking for her son.
The chief of police
wants to see you!
- Did he have anything?
- He knows the murderer.
He knows who killed Torben?
- He wants a reduced sentence.
- Out of the question.
We'll just have to talk
to his family, friends
- That could take weeks.
- What, then?
Cut a deal?
I totally agree
with Ingrid Dahl.
Yes, but we're talking about
a police murder.
Helge, stop being so pedantic.
Think creatively for once.
Yes!
Thank you.
- The chief prosecutor
- Not keen?
He owes me some favours
Well
Have you settled in well?
In the basement
with faulty phones.
Have you heard my bright idea?
I tried to sell it to Ulf once.
- A mobile office.
- Mobile office?
- May I?
- Please.
I would have told you
that Torben left the house.
But it slipped my mind.
- I'm sorry.
- This may cheer you up, then.
Henning Ravn's stuff.
Thanks.
He was storing his things here
during the renovations.
We want to find
his personal papers
which are in here somewhere.
So get going, eh?
Have fun.
No need to cart equipment back
and forth, you just take it along.
Yes?
What's your decision?
No, no. I understand.
You can't bypass him.
Yes. Thank you.
He'll okay it when the local
prosecutor's sworn in.
- He'll get him to call you.
- Fine.
Want to grab some lunch
with some female executives
who meet occasionally?
That's not me.
I just want
to be a good cop.
We're holding a man
who knows Torben's murderer?
Allow me to have
a little chat with him.
Stay here!
Maybe you don't give a shit,
but the rest of us do.
- Don't touch him.
- You know what he needs?
Cool it!
- I don't believe this.
- Ingrid Dahl here.
Great news.
Could you fax it to me?
Thank you.
When charged, all you'll get
is a suspended sentence.
No! It stays here.
What's said here
stays between us.
- Give me a name.
- Dennis.
- Dennis Friis.
- Dennis Friis?
Did his mum live
with Henning Ravn?
That's what this is all about.
After a gap of many years,
Dennis ran into Henning.
He told him
his mother had kicked the bucket.
And?
Henning rubbished his mum
and Dennis flipped out.
That same evening
he went out there and
- How do you know?
- We both work at the gym.
After the match I found Dennis
spewing in the loo.
He spilled his guts to me,
saying he'd killed two guys.
Dennis Friis?
A word, please?
About Henning?
I read about it in the papers.
He stayed with you
and your mum?
It didn't work out.
- Mum wasn't easy.
- And him?
He was okay.
I haven't seen him for years.
I'm sad he died.
For years?
You live locally
and didn't run into each other?
No.
- What are you doing?
- Trying to lift 300 kilos.
- I work relief here.
- And two days ago?
Yes. We were all watching
the match.
You were?
Don't waste our time.
At least ten people confirm
Dennis was watching TV.
- He left in the middle.
- And no one saw him?
I did.
I saw him from the bar.
I saw something was up.
When he got back
he'd changed gear.
- Is he lying to get off?
- I don't think so.
You saw the centre.
Could he have left unnoticed
from the back?
- In theory. Yes.
- That's enough.
- He has the motive.
- Revenge?
On the word of a criminal!
Find the knife.
He changed at home.
Shall we pay him a visit?
- We won't get a warrant.
- We could call when he's out.
Fine. Let's get it
over and done with.
Why not? Now we've started.
Look. All these
are from his mother's funeral.
- Don't they go on the grave?
- Yes, but he's kept them.
Yes
- Shall we start?
- Yes.
The chief of police tells me
you went behind my back.
- I thought you'd agree.
- That's not the point.
The fact is, I wasn't told.
- You also rehashed old stuff.
- What?
The mobile office.
All applications
go through me, right?
It just popped up.
I didn't apply for it.
That's how it was taken.
- Yes?
- No murder weapon at Dennis's.
Hi, Ulf.
Wait
- What search?
- Hardly a search
- Without a search warrant?
- We had no choice.
Ingrid, I didn't hear this.
Forensics can identify the knife
from metal traces they've found.
Ulf.
Now you can do
this investigation a big favour.
How?
the murder weapon.
Ulf Thomsen is here with me.
Do you view this discovery
as a definite breakthrough?
No, it's too early to say.
We'll have to wait
for Forensics.
- They can work wonders.
- Great, Ulf.
If Dennis doesn't go
for the knife, he's not our man.
Surveillance of suspect
20:08, Saturday June 19
Nothing's happening.
- What if it isn't him?
- You saw the flowers.
Yes. So he loves his mother,
that doesn't make him a killer.
What if it isn't him?
Ingrid's brilliant plan fails.
- Your optimism is contagious.
- I'm a realist.
We could be sitting here waiting
while the real killer
is dissolving the knife in acid.
- That's funny.
- Thanks.
- Too late?
- I think they've left.
Then I've got the whole house
to myself.
Oh, well
"Die Flle fhrt zur Klarheit.
"Lm Abgrund wohnt
die Warheit."
What's that?
One of Torben's favourite quotes.
Schiller
I never understood it.
Only fullness leads to clarity.
The truth dwells in the abyss.
I get that,
but what does it mean?
First you look
at the big picture,
then you look into
the human abyss.
Know what I'm looking at?
A man in a bed-sitter
jerking off.
- It's been two hours.
- He'll move.
- Are you still seeing
- Rasmus?
Yes.
I can't handle cops.
That's all we meet. And crooks.
The way we behave,
we're one and the same.
- What's that?
- Henning's personal papers.
That's what you wanted, eh?
Tax returns, letters, insurance,
receipts and all that.
- Great.
- He's on the move.
- Is he going to training?
- At this hour?
Fischer
You've been here before.
What's that?
The toilet, I think.
Hell! He puked in the loo.
Oh, it's you!
I thought it was a break-in.
- Give me your hand.
- I told you, I work here.
- I'm cleaning. At night.
- The other hand!
Dennis Friis It's 23.31.
You're under arrest.
Hey, Fischer.
Interrogation of suspect
01 L35, Sunday June 20
You don't have to talk
for our benefit.
We've got your knife.
Forensics will find something.
You left oodles of tracks
in your flat.
Your clothes, your shoes,
a hair you lost
Do you want a cola?
Yes. I'll get it.
Dennis, you've just lost
your mother.
Was it hard for you?
We saw all the flowers
from her funeral in your flat.
You ran into Henning
in the street two days ago.
Was he happy to see you?
You were very fond of Henning,
weren't you?
We found some letters
you wrote to him.
"Dear Dad"
Is that what you called him?
Or was that what he wanted?
"When will you visit us?
I miss you and so does Mum."
You were 15
when you wrote that.
Here's another one.
"Dear Dad, I've bought
two tickets to the soccer match.
"One is for you."
Did he turn up?
Or did you sit next to
an empty seat during the match?
When you met him, did you
tell him your mother was dead?
Was he sad?
Or just indifferent?
- I can see why you got angry.
- He said Mum
That my mum
was a good screw, but crazy.
And that I hadn't looked
after her.
He said I had let her down.
He let her down.
She'd been sick
since he left her.
That was why she took
those pills.
You wanted to tell him
so you went there that night?
Yes.
I just wanted to scare him.
But suddenly I'd stabbed him.
What then?
I looked for something
to stop the bleeding.
I wanted to help him.
But when I got back
he was hiding in the bedroom.
He was calling the police.
I stabbed him again.
Then the other one came home.
I didn't mean to.
He had nothing to do with it.
- She's good.
- Yes.
Torben wanted to get closer
to the moment of the crime.
And the last thing he did
was to step right into it.
Yes
Well
- There's still time.
- For what?
Your family in Norway.
I have to write up the case.
- I'll do that.
- No way.
I worked with a chief
for eight years
who ruined his marriage
because of the job.
I don't want a repeat of that.

Has she bought an office
or a container?
It was bloody expensive.
- Did she apply for the job?
- No.
- The deadline's today?
- Yes.
- Haven't you been inside?
- We're waiting for you.
- You know the deadline's today?
- Yes. Thanks for reminding me.
Here!
Come on.
Dennis Friis was sent to prison
for ten years for the murders
of Torben Rome and Henning Ravn
