01x02 - Episode 2

[bunniefuu]

(Joe) I'm on a train called

the Heart of Britain.

It's the Glasgow to London

nightsleeper service.

The wiring in the floor's

been tampered with

and there's a device attached.

One of the UK's biggest

antivirus firms has a virus.

(Saj) Just leave it to us.

(Joe) Before we left the station,

there was an incident

on the platform.

- (woman screaming)

- A lad stole a bag.

- (glass shatters)

- Police!

(Joe) It must have happened then.

Saj, the critical infrastructure

that uses the antivirus

Yeah?

It's not the UK rail network, is it?

- Is it an expl*sive device?

- No, it's a hacking device.

There's currently an Interpol red

out for someone on that train.

- What are the chances?

- This is ridiculous.

Hey!

(Saj) He actually used to be a DI

in the Met.

Who's going to have

operational control?

- You are.

- You mean it?

Do not, under any circumstances,

call Paul Peveril.

(beeping)

(whirring)

(Saj) They're saying

it's left the station again

with some passengers still on board,

but without the driver.

Any driver.

Every train across the country

stops right now.

(sobbing)

- Mouse!

- Mum!

(announcer)

Passengers are reminded that

(distorted voice)

My name is The Driver.

I'll help you. But you're going to

have to help me too.

Why would I possibly do that?

I mean, how can I trust you?

(Joe) Abby, I know what you're

thinking, how it looks, but

I haven't hurt anybody, all right?

I was one of the good ones, I was.

I haven't done anything.

And right now, we need each other.

So all I'm asking

is that when I've helped you,

you keep me out of custody

till my trial.

OK?

OK. Here's how it starts.

You need to ask the police

to track down

the two guys who ran out of

Glasgow Central.

We need to know where they came from

and who they were with.

Yeah. I'm going to put you on hold.

- Meg, look after this.

- Mate?

Mate

(mobile beeps)

What's going on?

(thudding)

What are you doing?!

- Excuse me. Hi.

- (man) No, not now.

I'm Abigail Aysgarth,

acting technical director

of the National Cyber Security

Centre across the road.

I'm, er, aware of all the glitches

across the network.

Can I check your systems?

(man) Er

OK.

Cyber security? Good luck.

(Abby) What problems

have you got in here?

Well, you know that all trains have

been grounded, every single one?

Yeah. I ordered it.

Well, look at that.

RTV, Real-Time Train Viewer,

should show the position

of every train in the country

at any given moment.

It's how we stop them colliding.

(operator) The whole system's down.

Network's currently littered

with passenger and goods trains,

all stopped where they shouldn't,

when they shouldn't.

So we're just blind.

I hope your message got through.

Because if any are still moving,

they won't be moving for long.

(opening theme music playing)

Hey! Could you step away

from that, please?

Do you know what's happening?

I know

the driver's still on the platform.

- What?!

- Right, I need to get into his cabin.

- You can't.

- There's no driver.

- We need to get into his cabin now.

- OK.

A Class 94 is not accessible

when moving.

Door to the driver's cabin's

at the front.

20 foot of engine between us and it.

Close it up.

- I thought you wanted us off?

- Where's that cop?

- Why are we moving?

- My lad's still on the platform.

He's still at the station.

- Has anyone seen the boy?

- Sorry, who's still on the platform?

- (Joe) You all right, mate?

- Yeah, I'm OK.

His mum's been left behind.

Give me my phone.

- (Joe) One sec.

- Is this to do with the hack?

What?

- What?!

- The what-what?

The wiring was tampered with

in the manager's office

before we left Glasgow.

There's been a device installed,

and a phone jammer that's presumably

meant to stop us

from doing anything about it.

- By who?!

- (Rachel) I don't know.

But he's been in touch with

the National Cyber Security Centre

through that.

(beeping)

Call through to the driver.

We need to go off at Carstairs.

He isn't on board either.

- What?

- What?

- What?

- What?

- Billy?

- It's true.

Who's driving, then?

I don't have all the answers.

Cyber Security Centre has actually

got me on hold at the moment.

No, someone else is in there.

Someone else is driving this train.

Yeah, someone else is driving,

but not from in there.

I think we're being

controlled remotely.

Yeah. I don't follow.

We appear to have been hijacked.

Hack-jacked.

Hijacks are so 20th-century.

(indistinct conversations)

It just ran a red

before Wishaw Central.

It should not be able to do that.

The red should trigger an automatic

safety response on the train,

putting the brakes on.

What, the fail-safe failed?

Yeah, well, antivirus

does have a virus.

And, Abby?

The minister is still on board.

Look, I've set up calls

with the train operating company

behind the Heart of Britain

and Five Eyes to see if anyone

has any idea who or what

this "Driver" might be.

Yeah. Yeah, OK.

Listen, you need to prioritise

regaining access to something called

the Real-Time Train Viewer

over everything else.

Right now, we literally have no idea

what's around the corner.

(Meg) Abs?

Meg, this is not the night

for Marrakech.

Well, yeah, well, I would go home,

but you've cancelled my train.

Look, is there any way that

you could stay in the station

and let me know if anything else

appears on those boards?

- (Saj) Yeah, er, one question.

- Er, yeah?

How?

Er

I don't know, but maybe it's worth

us trying to track back the guys

who ran away from the police

at Glasgow Central.

Who were they with?

Where are they going?

That is a police matter.

No, everything tonight

is a cyber matter.

And if you could check out

the DI's case

and get a comms plane dispatched

to fly over the train

and figure it all out,

in the time that it takes me

to climb seven flights of stairs,

I would really appreciate it.

(beep)

Hey.

I'm so, so sorry.

Mm.

I need new friends!

- Yeah?

- Yeah.

- All right?

- Yeah. OK.

(Meg) Right, good luck. Hwyl fawr!

Love you.

It is impossible for anyone

to operate this train

without a driver.

I disagree!

- On what basis?

- It f*cking is doing!

- Hey, hey, hey!

- Right! He's an old man.

I'm not too old

to deal with you, pal.

(all shouting)

(beeping)

- (Abby) Joe?

- Shush!

Shush!

- Hi. Have you got an answer for me?

- (Abby) Yeah.

We are looking into your case.

But listen, the Transport Secretary

is on that train,

and I need you to give this phone

to her.

Which one of you

is a Transport Secretary?

- What?

- Erm

Hello, everyone.

(Joe) They want to talk to you.

Oh, Jesus.

The one person I wouldn't want

in charge of a situation like this

is a member of this government.

(Erin) That is so bloody true.

Oh, please tell me

I'm not stuck on this train

with a bunch of bloody

Guardian readers!

- Shh!

- Hello. This is Liz Draycott.

Why don't we just Why don't

we just stick with this guy?

Yeah, that's not going to happen.

Why not?

He's the hero of Glasgow Central.

He is the reason the police

were at Motherwell.

Do we really have to

bring this up now?

Are you at the train manager's

office yet?

Look, I need to make a lot of calls.

You're not making any calls.

(Liz) Sorry, what's your name?

It's Abigail Aysgarth,

acting TD at the NCSC.

Well, listen, Ms Aysgarth,

I'm the permanent

Minister for Transport.

And I have to tell you, being

trapped on a train without a driver

is the worst possible

development for me,

so calls are going to be made.

Now, I need to ensure

that I am off this thing

before anybody else out there

knows I'm on it.

That phone is used to converse only

with us and to connect to the SBC.

That little flashing device in front

of you with the aerial on it, yeah?

That is what's controlling

the train now.

I need you to link the two by USB

and get me that phone's IP address.

Do you have any idea how to do that?

(scoffs) I co-sponsored last year's

ICT and telecommunications bill.

Do you have any idea how to do that?

No.

That's OK. I'm going to put you

through to my colleague,

who will talk you through the plan.

And we're going to pull

all the data from the SBC,

put it in a little safe place

called a sandbox,

figure out how to stop it

and get it right back.

OK?

OK.

(beep)

(Tobi) Hello, Minister. Tobi here.

OK.

Well, look at you!

What, dressed for Marrakech?

Sounding like a technical director.

Hey, er, can we skip the hugs

and get straight into business?

And that is why I like you.

There's been a hack-jacking.

Hey, my colleague's coming down

in a minute, but can we?

(guard) Sure.

It's the Heart of Britain

nightsleeper service

from Glasgow to London.

Oh, the new 94s with the Mk 16s?

Yeah, I believe so.

There appears to be

phone jammers on board

which have delayed

raising the alarm.

(guard) Hand over your phone,

please, sir.

What about UK Rail?

Under attack from its own antivirus.

But we have still got control

of the points,

most of the signals.

Most of the trains are grounded.

There's glitches everywhere.

And we haven't got access

to something called the RTV.

So you can't see anything

that's in the train's way.

(Abby) Can't we just cut

the electric?

West Coast Main Line,

that is electrified, isn't it?

Won't that stop it?

Not with the Class 94s.

They're bimodal.

What?

They've got diesel backup.

They can still run for hours.

No, you need to speak to the TOC.

- (Abby) Who?

- The train's operating company.

The thing is,

they're built by X, owned by Y,

leased by Z, maintained by

Oh, should've started with

a lower letter, shouldn't I?

You've got TOCs, ROCs,

ROSCOs, DUs and FOCs.

This is why I need you.

(Miller) Abby.

Could I?

You did tell her I was coming?

- Ma'am, I

- In private.

This must be very painful for you.

This man has upset everyone

it's possible to upset.

I called it, you ignored it,

and now look where we are.

He is the Michelangelo

of mansplaining.

I know stuff that

other people don't.

Am I meant to keep it a secret?

You leaked confidential information

to the public.

I tried to alert the public

to the dangers because you

Because you thought

you should have my job.

You Liz Trussed your way into that

position, ignoring every warning,

- and now you've just got to accept

- He leaves!

I'm leaving!

(tense music playing)

Do either of you even care

about the people on that train?

This is not the time for

"I told you so's".

And, ma'am, this is currently

a severe threat to life,

and nobody understands

the complexities of transportation

better than him.

Please put your faith in me

and let us through, cos

well, my pass is at home,

the only thing I've got in

my pocket is £200 worth of dirham,

and I'm pretty sure the guard's

not allowed to accept that.

Yes!

Erm, the minister has,

somewhat reluctantly,

granted us access to the SBC.

We're pulling the data now.

What I always say - there's

the right way, the wrong way

and the railway.

Oh, God. It's Obi-Wan in a gilet.

Still can't do lifts.

(lift) Doors closing.

So, I searched this property

when I was with the drug squad.

Found some cash, booked it in,

then the suspect comes back

and claims there was a load more.

That's what they do,

they try and hold things up.

Only then, Professional Standards

are on it.

They decided I'd taken the money.

You were charged?

I didn't take anything.

- You ran, though.

- (Joe) I went into hiding, yeah.

But don't take that

as a sign of guilt.

Take that as a sign I wasn't

too keen on being locked up

with the person I just arrested.

What a bag of shite!

(Chrissy) I'm still on here

because of you.

They knew they had to get us all off,

but they couldn't open all the doors

because of you.

Excuse me. We're ALL stuck on here

because of you.

You're still here

cos you wanted to finish your drink.

Look, I'm sorry.

It's OK.

- How is it OK?

- I think you need to leave.

I would if I could.

No, down the other end of the train,

away from us.

- Yeah.

- Mm. Agreed.

Yeah.

(Geoghan) So

are you going to go willingly

or not?

- (footfalls pounding)

- (Abby panting)

Right, we have pulled all the data

from the SBC and isolated it.

Now, the code is camouflaged, but

I'd hope we'd be able to crack it

and use a satphone to put it back

onto the train within half an hour.

What about the RTV?

Yeah, OK.

One thing at a time, all right?

Yeah, that's not

going to work tonight.

(beep)

That was triggering.

Standing between two old people

who hate each other

is taking me right back

to family holidays.

Elvis is in the building!

(all murmuring)

(Abby) Er, yeah, for those of you

who remember Pev,

this is his comeback special.

Catch him here tonight

for one night only.

And for those of you who don't,

well, try not to be offended

cos that is just the way he is.

- Where is everyone?

- Trying to contact them.

There's quite a lot of

"do not disturb".

- OK. Er, Pev?

- Yeah.

Take over Saj's desk.

You're in charge of taking control

of the RTV.

Hang on a minute.

What are you doing?

Do you understand it?

I'm getting there, all right?

- Do you?

- Better than I understand myself.

Hm!

(Pev) Right.

Ma'am, even though we are acutely

aware of the unprecedented events,

I am confident that we can bring

this under control within minutes.

- (mobile rings)

- OK. Sorry.

Already?

(Meg) Already.

(announcer) Passengers are reminded

to pay 600 Bitcoin

to account 3FZbgi29cpjq2GjdwV

Erm, it's about ten million quid.

(announcer) or London really will

be its final destination.

(Miller) What does that mean?

(Saj) It means the train

is now a guided m*ssile.

(tense music playing)

(beeping)

- Really?

- (Geoghan) Yeah.

(scanner beeps)

(Joe) All right.

(indistinct conversations)

OK, everyone.

Everybody? Up here.

It's almost 0100 hours, and

a ransom demand has just come in.

Which suggests we are dealing

with organised criminality here.

Leon, I want you to lead a team

focused on the antivirus virus

and ensuring we keep control of as

much of the rail network as we can.

Zed, you're all about the train.

I want you to pull as much code

as you can from that SBC,

work in the sandbox

and find that k*ll switch.

Then we can send it back to the SBC

via the minister and the satphone

and regain control.

Both of you report to Saj.

Saj, report to me.

Right?

Come on! (clapping)

This isn't some company going down,

this isn't money being lost -

this is imminent threat to life,

and this is on us.

Tobi? The minister?

- She She hung up.

- (beeping)

Oh, for f*ck's sake.

OK, great.

- (Mouse) Where are you going?

- Oh!

You've got a bad habit

of appearing out of nowhere.

Tell me I'm not the only one

who can see you.

I mean, if you were hiding, like

what's made you come out?

Why WERE are you going to London?

You're not getting out.

We're stuck in here until it stops.

I'm not.

I'm not.

(banging)

(Joe grunting)

(device chimes)

Oh, f*ck.

Mark Hudson,

senior field at security,

liaising with Police Scotland

and military response.

Anything that isn't our domain

is his.

Hud, this is Abby, acting TD.

What? Where's Pete?

Er, Peter's been off for months.

You know, I really think

we could do with Peter tonight.

Peter is at the point

where every single incoming email

is causing his

An hour ago, you thought it

was fine for the technical director

to go on their holidays.

Now you think we need two?

Yeah, well, a lot can happen

in an hour.

- Get him in.

- (Miller) No.

Abby is definitely in charge.

Gave you a job to do.

Firstly, and most importantly,

I do not work for you,

I work with you.

Never, ever forget that.

Secondly, we have dug into

a shitload of CCTV

from Glasgow Central and

we don't believe that anyone else

boarded the train or left it

in the ten minutes of interest

leading up to its departure.

So whoever installed the SBC

carried on to Motherwell?

And is either one of the majorly

pissed off 108 people

we're currently holding

in the waiting room there, or

One of the 12 still on the train.

Er, not the policeman, though.

Former.

He's the only person who actually

stays inside of the cameras

for the entire ten minutes.

Did you look into his case,

the detective?

Yep. Sending over the details now.

He's got multiple commendations

from his chief.

His record was basically A1

until he tried to slip 200K

into his back pocket.

Oh, he's done close protection

and K&E hostage negotiation.

We could be lucky

that he's on there.

We will not be working

with him again.

Can you put Special Forces

onto the train from the air?

Subject to ongoing assessment,

but the initial response was

"not at this speed" -

too many tunnels, bridges

and overhead wires.

You are aware there's been a demand?

Yep, some twat's already tweeted it.

Six twats retweeted that.

Seven, eight

Hud, Abby has been working on

a strategy that could allow us

to crack the code in a sandbox here

and use the satphone on the train

to inject it back into the SBC.

Nicola, I don't know

what the hell any of that means.

We could stop the train.

Clearer.

Is the electronic intelligence

aircraft on its way?

A comms plane? We ordered one.

This isn't Deliveroo, my love.

You don't order - you request.

We need to know how that single

board computer is being controlled.

I'll take it up the chain.

Room's ready for Cobra, ma'am.

And BBC News are chasing

for a statement.

Let's reveal that the network is

currently subject to a cyber attack,

but keep the fact that there is

an active hostage situation

out of the public domain

until we've resolved it.

And how long exactly might that be?

(scoffs) Minutes?

Minutes.

And there won't be a collision

before then?

We can't say that,

because we can't see anything.

But what I can say is that

we've got our best man on it.

(computer chimes)

So sick to get to work with you.

Everything you've done

since going private, it's like

pretty much the model for me.

Well, it shouldn't be.

This, here, if it works,

if it's allowed to,

is the best place in the world.

I'm only here for the toys.

If I had it my way, we'd get rid

of governments altogether.

Sure a good algorithm

could do it better.

Oh, God help us.

He wouldn't need to any more.

Oh.

(Geoghan) You've reached

the voicemail for Daniel Geoghan.

Leave a message.

I've got every faith in you, Pev.

Yeah? Well, normally

that would be well placed, but

Er, can I

tell you something in confidence?

I am currently under the influence

of my first Class A substance

since the '90s.

It's been six years since I left HQ.

I thought it was finally safe to,

you know, let my hair down.

You got any more?

I can get rid of it.

Take it.

This is no time for a come-down.

(Billy) Can I help you?

I'm assuming

class divisions no longer apply.

Criminals in standard.

You remind me of my dad.

Oh!

I hate my dad.

I won't be checking tickets.

Hi, everyone. I'm Billy and

my colleague Yas will be

getting everyone's details

for the authorities.

Delay Repay is not going to

touch the sides here.

This is a train operator's dream -

driverless train on the main line.

They won't see this as a warning.

They'll see this as the future.

Christina Doolan,

223 Haverty Street, Ealing.

Are you OK?

- I've been better.

- Aye, and been worse.

Guys. Guys!

We're going to be all right.

How will we?

Can you imagine

how many government agencies

are involved in this right now?

We will be fine!

(cutlery clatters)

What are you doing?

I'm just making a note

of everyone's names.

What?

Why?

I'm a a journalist.

Oh, for f

(Liz) Yes, I'll hold.

(beeping)

(knocking)

That That's, er, my private phone.

It's been nationalised.

I really need it tonight.

Not as much as me.

(aide) Thank you for holding.

I'm afraid the Cabinet Secretary

can't be reached

at the moment, ma'am.

Yeah, I don't think you understand

how important this is.

(Tobi) Abby, got the CCTV back.

It shows the guy who snatched

the bag at Glasgow Central

meeting the woman he snatched it

from, an hour earlier.

It was her bag he snatched.

And what happens between this

and Glasgow Central?

(Tobi) OK, so these three go

straight to the concourse,

but the one with the pram goes

into a hotel near the station,

is there for about 25 minutes.

(Abby) Why not go straight

to the station too?

Speak to Hud, see if they can

get footage from inside the hotel.

If not, get it yourself.

I know you didn't take it.

The money.

If you'd taken loads of money,

you'd have better clothes.

No, I mean, like

I like your clothes, but

I think you look quite like me.

Yeah, it's like a mirror.

No, not now, but when I'm older,

or you when you were younger.

You got kids?

(conversation in French)

Er, je

Who is this?

Er, it's the guy from Voyarapide.

The company that runs

the Heart of Britain is French?

Yes, well, the TOC is.

But the carriages are owned

by a ROSCO that's German,

and the locomotives run under

contract by an FOC that's English,

who leases them from

a separate ROSCO - Spanish. OK?

Abby. Acting technical director.

(mobile translates)

We're trying to establish

whether you're aware

of any vulnerabilities within

the train's systems

that might have enabled this?

(mobile translates)

(translation) There have been

no issues at this end whatsoever.

Our systems and our partners

are robust.

(speaking French)

(translation) And it's clear to us

that generational underinvestment

in your transport network

is to blame.

(speaking French)

(translation) This is a UK issue,

not a French one.

With all due respect,

this is not the time for

(Saj) Good work, director.

- Hey, I know this is awkward, OK?

- Mm-hm.

Obviously, when I said

what I said this morning,

I wasn't expecting to be

spending the night with you.

I'm not bothered about that,

all right?

Well, you seem bothered.

If you want to end a relationship

the night before you go off

- on your wild weekend

- Relationship?

Slightly overstating it.

OK, so it wasn't even

a relationship now, yeah?

Hey, for you not to call me

when you found out about the virus

just because you were

Oh, my God, I did not call you

because you were on holiday.

I was at the airport!

Yeah, well, I didn't know

your flight was delayed.

(mobile beeps, line rings)

Minister, pick up!

(mobile rings)

- (ringing stops)

- (sighs)

- (line rings)

- Excuse me.

I've got the details

of everyone still on board.

Have there been any messages for me?

- Nope.

- When there is - WHENEVER there is -

can you let me know?

Mm-hm.

- (people clamour)

- (mobile rings)

We're dealing with it. Now, go on

(indistinct conversations)

(Kate) Hello?

Kate, it's me.

(Kate) Oh, my God, Liz! Are you OK?

What do you think?

There's a multi-agency

response under way.

- They're throwing everything at it.

- We need to come up with a strategy.

Liz, you're in the middle

of a critical incident.

Forget policy.

You need to speak to

Downing Street, Kate.

This isn't just about

cancelling next week's announcement.

- This is about

- Liz, we're all acutely aware

that something like this

happening a few days before

Remove all traces of it, OK?

All traces.

Do we have access to the RTV?

We have progress.

Not the same thing.

Ma'am.

(Miller) Abby, a word in private.

Hud has been instructed to get the

military fully involved and ready.

No-one is going to pay that ransom,

so if we don't take care of this -

if YOU don't - they will.

And things may get very, very messy.

Does anyone object to me

having a drink?

- No, I think that's a good idea.

- OK.

- So what is it you do, then?

- Ignore reporters.

The prices are in there.

I'm not paying.

Now, come on. The least

you can do is make this a free bar,

considering the circumstances.

I think alcohol is the last thing

we need right now.

Ha!

You speak for yourself, eh?

Actually, I'll have a glass

of something.

There we go, that's the spirit.

Now, everyone in favour say aye.

(in unison) Aye.

(sighs)

(Abby) We're making progress

on the SBC.

Where are you at

on the network virus?

I'd say we're looking more

in terms of days.

Er

Do you know the problem

with this place?

It's that I never really

fully feel confident

that the person I'm talking to

hasn't spent their weekends

rifling through my phone and email.

Mm.

It's not the same for you, Leon.

You know the red lines.

(chuckles)

You need to forget them tonight.

Get in to Voyarapide's systems.

Do whatever you need to do.

I think they're covering something,

a system weakness.

If we can find their vulnerability,

we can patch it.

Hm?

Yeah.

Do that and you're dead.

They slow it down when we corner.

Big corner, big chance.

Abby, I think we're almost there

with the code on the SBC.

If we could have communication

back with the train to upload it,

- we should be able to stop it.

- Great.

- You've reached the voicemail

- Calling her.

- Leave a message.

- (beep)

Minister, we need that phone line!

OK, let's do this.

Ready? OK?

(static)

(distorted voices) We regret

to inform you that

We regret to inform you

that access is denied

See it, say it, sorted

See it, say it, sorted

What's happening?

It's a tripwire.

(Saj) The SBC's interface basically

appears to be cloning itself

many, many times,

hiding the real one.

Meaning?

It's not one step forward,

TWO steps back, ma'am

It's about 7,000.

Yeah, and counting.

(distorted voices) Access is denied.

We regret to inform you

- You having a drink?

- No, no. No.

Thank you.

(breathing shakily)

Come on.

Oh, no, I don't

(Erin) You're one of us now.

Quintinshill soon.

What?

Quintinshill.

Worst rail crash in UK history.

230 dead.

Many more injured.

Many, many more.

(Mouse) You really think

you can make it?

Soon find out.

What about me?

I could have said, you know,

that you were in there.

But I didn't, cos I knew

you didn't want me to.

So why won't you do something

for me?

Don't leave me.

All right.

All right.

How is it possibly all right?

They're taunting us.

How long will it take now

to find the right interface

and do what you thought

you were about to?

- Not minutes.

- We haven't got hours.

When the minister calls back,

I could try and play with the SBC

directly and drop the sandbox.

This isn't a game.

This is about people's lives.

We test everything first.

(Miller) Speed it up,

and put Saj back in charge of

regaining control of the RTV.

We need it now more than ever.

This isn't an accident

waiting to happen.

It's a m*ssacre.

And your pick

is doing nothing to change that.

He is working on it.

Is he?

Is he under the influence

of something?

Ma'am, he's trying his best.

And I'm doing mine.

(mobile rings)

Minister, hello.

Oh, hi. Are you ready for me

to connect it again?

Hello?

What have you been doing?

Look, I told you, didn't I?

Right, I've got a list,

the host has,

of the people still on board.

Do you know how long this will take?

I've got a lot of calls to make.

Hello?

Hello?

Is the host there right now?

Yes.

Could you pass the phone to him

for a minute, please?

- What?

- Please?

It's the cyber security centre.

They want to speak to you.

- Hello?

- (Abby) Hi. Listen.

I don't want you to give this phone

back to the minister.

I want you to turn around,

find the policeman

and give it back to him.

Where are you going?

(rumbling)

OK. Even if we did crack

the SBC just then,

we couldn't have stopped the train

because we didn't have contact

with it.

(Liz) Excuse me!

Why? Because the Secretary of State

seems so focused

on saving her own skin.

She's in a very difficult situation.

Well, what the f*ck are we in?!

(alarm beeps)

You told me that I was in charge.

This is what it looks like.

And if I have to make promises

I can't keep, then I will,

because I don't care

what this guy might have done.

I care about what he CAN do.

(alarm beeping)

You're all the same!

And you accept full responsibility

for that choice?

I do, ma'am.

(mobile chimes)

Five Eyes in your office.

Two minutes.

(keyboard clacking)

Nothing by 1:30

and Elvis leaves the building.

(alarm beeps)

Excuse me.

What's that light for?

(Billy) Sorry.

(tense music playing)

(breathing deeply)

OK.

(man) Do you know that Peter's left?

(woman) Couldn't they get him back

for just one night?

Hey. Sorry I'm late.

If you have any leads on

this "Driver", now is the moment.

I'm sure we'd all accept that,

after Russia and China,

there is one state that hacks

on an industrial scale

that we do not like to talk about.

And I think we're going to have to

discuss "l'elephant dans la piece",

don't you?

Yeah, but France doesn't hack

French companies, does it?

It hacks us for them, so

My team is going to send through

everything they can

about something called

the Blue Blockade Group, BBG.

Well, er, I know it,

but they've never done

anything like this before.

No, but our latest HUMIN

suggested they were planning to.

And where are they getting

their resources from?

They're a group based out of Tehran.

No-one's really thinking the fact

that your Transport Secretary

is aboard is a coincidence, are they?

I think we all need to accept

this is just as likely to be

the work of a politically motivated

group as it is organised crime.

(audio distorting) And I know that

is not what you want to hear.

(alarm beeping)

(scanner beeps)

No

- (Mouse) Yes!

- Huh?

(video game) Yahoo!

(Billy) Hey!

What have you done that for?

You might like it on here.

I mean, you're getting paid.

Should the chance present itself,

I think the rest of us

would quite like to get off.

Here.

She wants you.

(man, distant) If you had HUMINT,

why would you not share it?

(woman) We have to protect

our sources.

(man) We have to protect each other.

(woman) Yes, but if I may

(Joe) Abby? Are you there?

- Joe?

- (woman) Um, where is she going?

(Saj) Apologies.

This is a very difficult situation

Joe.

I'll do my best for you

if you'll do your best for me, OK?

You can't choose a criminal

over a member of Parliament.

In the Venn diagram of the two,

I think there may actually

be quite the shaded area.

(Joe) I'm not a criminal.

I was wrongly charged with a crime.

(Abby) Minister, he's the one

who called us,

he's the one who's trained for this,

and he's the one who I believe

has the best chance of

stopping that train, OK?

Abby, I'm all yours.

What do you need?

I really don't like how dependent

we all are on that one phone.

I'd feel a lot better if you could

find that phone jammer

and shut it down.

Do you know

what you're looking for, Joe?

Yeah, I think so.

Right, it's about this big,

it's got an antenna on top,

its own power supply.

Check the bags. Every one.

About the size of a shoe box.

Abby, comms plane's

almost reached the train,

and it's ready to scan a signal.

We should know exactly what's

going on in there within minutes.

Thanks.

Tobi, stay with Leon

and report straight back to me

the moment you have a result?

Yeah.

Ma'am.

(Miller) Mr Peveril.

Er

Oh.

- (rock music blares)

- Whoo!

Did you do it?

Did you doubt it?

- Send it.

- Sent!

Oh!

(Pev) And with the Heart of Britain's

location, in real time.

You're welcome!

Whoo!

(cheers)

When I grow up,

that's who I want to be.

(Abby) What's that?

It's a goods train.

Stalled.

With its engine and half its load

straddling the West Coast Main Line.

All right, you keep searching here.

I'll check the next carriage.

I'll help.

Stop that!

(controller) Hello,

West of Scotland Signalling.

Hello, Cowlairs.

This is Abigail Aysgarth.

I need you to move what appears

to be a substantial goods train,

currently stationary

on a stretch of track,

crossing over two lines

at Gretna Junction.

Can you do that immediately

for me, please?

(controller) No.

Excuse me?

(controller) That is beyond

our jurisdiction.

You'll need to talk to

the control desk down at Manchester.

On it.

- Ma'am.

- (newsreader) All trains have been

- That's our train.

- (newsreader) Social media footage

- No!

- suggests some are still moving.

(Pev) Got it.

OK, Manchester,

0161 496 9865.

(scanner beeps)

(controller) Direct comms with

maybe two-thirds of our trains

are currently down.

Do you have a mobile number

for the driver, maybe?

(controller) I thought we did,

but it seems to be out of date.

A name, then?

(controller) Erm Harvey Driscoll.

- Pev.

- (Pev) Yeah.

(Abby) Control, what are the goods

on the train?

- (controller) Tankers.

- (Abby) Containing?

(controller) Natural gas condensate.

OK, thank you.

(Pev) Driver. Already ringing.

(line rings)

Come on, come on!

Come on.

(Miller) What else have you got?

Abby, what else have we got?!

(Joe) Abby? You there?

- Joe.

- I found something.

Hey, hey, you need to move everybody

out of the front carriages

and prepare for impact.

What? Why?

There's a train on the line

in front of you.

(mobile rings)

- Hello?

- Hiya. This is Harvey Driscoll.

Harvey! Harvey!

Harvey, hello.

This is

the National Cyber Security Centre.

We need you to move your train

fully off the Glasgow South Western.

(Harvey) All trains are currently

grounded, I'm afraid.

- Harvey

- (Harvey) I'll try and give it

(Abby) I need you to move your train.

(Harvey) Can't guarantee anything.

(Abby) We've spoken

to the control desk.

Listen.

(Harvey) Er, I've got

very little battery.

(Erin) What's that?

There is another train

that's not grounded

and it is moving towards you.

- (Harvey) Well, stop that, then

- (line disconnects)

We can't I

(tense music playing)

Everyone needs to move

down the train, now!

- Huh?

- Why?

(Joe) Now! Now! Come on!

We're going to hit something.

- Hit what?

- That!

Come on!

(Leon) Estimated time

till impact, 90 seconds.

- Oh, Jesus!

- Come on!

(all shouting)

Come on.

Come on. Quick.

Come on!

(Leon) 70 seconds.

Look.

(engine rumbles)

- Come on, quick.

- Come on!

(Pev) It's moving.

(wheels squeal)

Joe?

Come on!

(Leon) 30 seconds.

Come on, come on, come on, come on.

Get up. Get up. Come on.

(Leon) Ten seconds.

(alarm beeping)

(objects clattering)

(all shouting)

(all screaming)

(indistinct shouting on mobile)

Joe!

(closing theme music playing)

(Abby) Joe?

(Tobi) I'm not sure the person

who installed that device

is in the waiting room

at Motherwell.

I found a firearm.

Don't trust anyone.

(music continues)
