Original subtitles

I'm on a train called the Heart of Britain.

It's the Glasgow to London night sleeper 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.

Just leave it to us.

Before we left the station, there was an incident on the platform.

A lad stole a bag.

GLASS SHATTERS

Police!

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 explosive device?

No, it's a hacking device.

There's currently an Interpol Red out for someone on that train.

What are the chances? It's ridiculous.

Hey!

He actually used to be a DI in the Met.

Who is going to have operational control?

You are. - You mean it?

Do not under any circumstances call Paul Peveril.

DEVICE CHIRPS - CONTROLS BEEP

ENGINE HUMS

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.

Mum! - Mouse!

Mum!

Passengers are reminded that...

AUDIO GLITCHES ...my name is The Driver.

I'll help you.

But you're gonna have to help me too.

Why would I possibly do that?

I mean, how can I trust you?

Abby, I know what you're thinking

how it looks, but...

I haven't hurt anybody, alright?

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.

INDISTINCT CHATTER

Yeah, I'm gonna put you on hold.

Meg, look after this for me.

Mate...

LINE BEEPS

What's going on?

What you doing?

Excuse me. - Not now.

I'm Abigail Aysgarth, acting technical director

of the National Cyber Security Centre across the road.

I'm aware of all the glitches across the network.

Can I check your systems?

Uh...

OK.

Cyber security.

Good luck.

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.

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.

Cos if any are still moving, they won't be moving for long.

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, we need to get into his cabin.

You can't.

There's no driver!

We need to get into his cabin now. - OK.

TRAIN RATTLES

The 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.

DOOR SHUTS

I thought you wanted us off.

Where's that cop? - Where's the train manager?

My lad's still on the platform.

He's... He's still at the station.

Has anyone seen the boy? - Sorry. Who's still on the platform?

You alright, mate? Yeah, I'm OK.

His mum's been left behind.

Give me my phone.

One sec. - Is this to do with the hack?

What?

What? - The 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? I don't know.

But he's been in touch with the National Cyber Security Centre, through that.

LINE BEEPS

Call through to the driver. We need to get off at Carstairs.

He isn't on board either.

What? - What?

Billy? - It's true.

Who's driving then?

I don't have all the answers.

Cyber Security Centre's actually got me on hold at the moment.

No, s-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-I don't follow.

We appear to have been hijacked.

Hack-jacked.

Hijacks are so 20th-century.

INDISTINCT CHATTER

Itjust 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 failsafe failed?

Yeah, well, antivirus does have a virus.

And, Abby, the Minister is still on board.

SHE GASPS

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.

Abs?

Meg. This is not the night for Marrakech.

Well, yeah, 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?

Yeah, uh, one question.

Uh, yeah?

How?

Uh...

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.

But-- - 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.

PHONE BEEPS

Hey.

I am so, so sorry. - Mm.

And I need new friends, yeah?

Yeah. - Alright?

Yeah. - It will be OK.

Alright, good luck. SHE SPEAKS WELSH

Love you.

It is impossible for anyone to operate this train without a driver.

I disagree!

On what basis?

Fucking is doing! - Hey, hey, hey!

Right! He's an old man!

I'm not too old to deal with you, pal!

ALL SHOUT OVER EACH OTHER

LINE BEEPS

- Joe? - Shush!

Shush!

Hi. Have you got an answer for me?

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 the transport secretary?

What?

Um...

Hello, everyone.

They wanna 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.

That is so bloody true.

Oh, please tell me I'm not stuck on this train

with a bunch of bloody Guardian readers!

Shut up.

Hello, this is Liz Draycott.

Why don't we just... Why don't we just stick with this guy?

Yeah, that's not gonnae 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.

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 gonna 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?

I co-sponsored last year's ICT in Telecommunications Bill.

Do you have any idea how to do that?

No.

That's OK. I'm gonna put you through to my colleague

who'll talk you through the plan.

And we're gonna 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. - LINE BEEPS

Hello, Minister, Tobi here.

OK.

Well, look at you!

What, dressed for Marrakech?

Sounding like a technical director.

SHE SCOFFS Yeah.

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...

Sure.

It's the Heart of Britain night sleeper service from Glasgow to London.

Uh, the new 94s with the mark 16s?

Yep, I believe so.

There appears to be phone jammers on board

which have delayed raising the alarm.

- 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?

Can't we just cut the electric?

West Coast Mainline, that is electrified, isn't it?

Won't that stop it?

Not with the class 94s, they're bimodal.

What?

They've got diesel back-up. They can still run for hours.

No, you need to speak to the TOC. - Who?

The train's operating company.

The thing is, they're built by X, owned by Y, leased by Z

maintained by...

Oh, I should have started with a lower letter, shouldn't I?

You've got TOCs, ROCs, ROSCOs, DOs and FOCs.

This is why I need you.

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!

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.

SHE SIGHS Yes.

TOBI SIGHS Um...

The Minister has somewhat reluctantly granted us access to the SBC.

We're pulling the data now.

What I always say: there's a right way, the wrong way

and the railway.

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

Still can't do lifts.

Doors closing.

So, I searched this property when I was with the drugs squad.

I found some cash, booked it in

then the suspect comes back, claims there was a load more.

That's what they do, try and hold things up.

Only then Professional Standards were on it. They decided I'd taken the money.

You were charged?

I didn't take anything.

You ran though.

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.

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.

Mm, agreed. - Yeah.

Yeah.

So...

are you gonna go willingly?

Or not?

ABBY PANTS

Right, we have pulled all the data from the SBC and isolated it.

Now, the code is camouflaged but I'd hope we'll be able to crack it

and use the satphone to put it back onto the train within half an hour.

What about the RTV?

Yeah, OK, one thing at a time, alright?

Yeah. That's not gonna work tonight.

That was triggering.

Standing between two old people who hate each other

has taken me right back to family holidays.

Elvis is in the building!

WORKERS GRUMBLE

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

because that is just the way he is. SHE CHUCKLES

Where is everyone? - Trying to contact them.

There's quite a lot of do not disturbs. - OK.

Uh, Pev? - Yeah?

Take over Saj's desk.

You're in charge of taking control of the RTV.

Hang on, what are you doing?

Do you understand it?

HE SIGHS I'm getting there, alright?

Do you?

Better than I understand myself. - Hm.

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.

PHONE RINGS - OK. Sorry.

Uh...

Already?

Already.

Passengers are reminded to pay 600 bitcoin

to account 3FZbgi29

cpjq2GjdwV8...

It's about 10 million quid.

... JJnkLtk2zc5...

or London really will be its final destination.

What does that mean?

It means the train is now a guided missile.

Really? - Yeah.

LOCK BEEPS

Alright.

WORKERS CHATTER

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 kill 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!

This isn't some company going down, this isn't money being lost.

This is imminent threat to life, and this is on us.

WORKERS CHATTER

Tobi, the Minister?

She... she hung up.

Oh, for fuck's sake.

OK, great.

HE GRUNTS

- Where were you going? - Oh, God!

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 you going to London?

You're not getting out. You're stuck in here until it stops.

I'm not.

I'm not.

DOOR BANGS

JOE GRUNTS

DEVICE CHIMES

Oh, fuck!

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?

Uh, Peter has 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. 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.

Uh, 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's basically A 1

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?

Yeah. 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?

The 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?

SHE SIGHS 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.

It's so sick to get to work with you.

Everything you've done since going private'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.

I'm sure a good algorithm could do it better.

Oh, yeah. God help us.

He wouldn't need to anymore.

Oh!

You've reached the voicemail for Daniel Geoghan. Leave a message.

I got every faith in you, Pev.

Yeah? Well, normally...

that would be well placed

but, uh, can I...

tell you something?

Uh-huh. - In confidence.

I am currently under the influence

of my first Class A substance since the '90s.

HE LAUGHS

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 comedown.

WATCH TICKS

CARRIAGE DOOR OPENS

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 gonna touch the sides here.

This is a train operator's dream.

Driverless train on the mainline.

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.

And you've been worse.

Guys. Guys!

We're gonna be alright.

How will we?

Can you imagine how many government agencies are involved in this right now?

We will be fine.

CUTLERY RATTLES

SHE SHUDDERS Jesus...

What are you doing?

I'm just making a note of everyone's names.

What?

Why?

I'm a... a journalist.

Oh, for f...

Yes, I'll hold.

LINE BEEPS

HE KNOCKS ON DOOR

That-that's, uh, my... private phone.

It's been nationalised.

I really need it tonight.

Not as much as me.

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.

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?

OK, so these three go straight to the concourse

but the woman with the pram goes into a hotel near the station

is there for about 25 minutes.

Why not go straight to the station too?

Speak to Hud, see if they can get footage from inside the hotel.

If not...

SHE WHISPERS ...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?

Je comprends rien.

Vous me réveilliez à deux du matin pour ça? Oui.

Vous m 'appelez la nuit, mais y'a personne qui parle français là-bas?

Je vais...

C'est pas français, ça!

I, uh... Uh, je... Buh... HE SIGHS

Who is this?

Uh, 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 ROSCO, that's German

and the locomotive's run under contract by an FOC that's English

who leases them from a separate ROSCO, Spanish, OK?

TRANSLATION APP CHIMES - Abby, acting technical director.

Abby, directrice technique intérimaire.

We're trying to establish whether you're aware of any vulnerabilities

within the train's systems that might've enabled this.

TRANSLATOR APP REPEATS IN FRENCH

HE SPEAKS FRENCH

There have been no issues at this end whatsoever.

Our systems and our partners are robust.

HE SPEAKS FRENCH

And it's clear to us that generational underinvestment

in your transport network is to blame.

C'est un problème britannique, pas français!

This is a UK issue, not a French one.

With all due respect, this is not the time for--

SCREEN BEEPS

Ce n 'est pas le moment...

Good work, Director.

Hey, I know this is awkward, OK?

Obviously when I said what I said this morning

I wasn't expecting to be spending the night with you.

Listen, I'm not bothered about that, alright?

Well, you seem bothered.

If you wanna end a relationship the night before you go off--

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.

PHONE BEEPS - LINE RINGS

Minister, pick up!

PHONE RINGS

SHE SIGHS

LINE RINGS - Excuse me.

I've got the details of everyone still on board.

Have there been any messages for me? - No.

When there is, whenever there is, can you let me know?

Mm-hmm.

CROWD CHATTERS

Now! We're dealing with this now!

No, I'm not--

ANGRY OVERLAPPING CHATTER - PHONE RINGS

Hello?

Kate. It's me.

Oh my God, Liz, are you OK?

What do you think?

There's a multi-agency response underway, 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, 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.

Abby, a word in private.

SHE SIGHS 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.

KEYPAD CLICKS

Does anyone object to me having a drink?

No. I think that's a good idea.

So, what is it you do then?

Ignore reporters.

The, uh, 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's the last thing we need right now.

Ha!

You speak for yourself, eh?

Actually, I'll have a glass of something.

Well, there we go. That's the spirit.

Now, everyone in favour say aye.

Aye!

SHE SIGHS

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.

Uh...

Do you know the problem with this place is 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.

Yeah.

It's not the same for you, Leon.

You know the red lines.

HE CHUCKLES

You need to forget them tonight.

Get into 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.

Hmm?

Yeah.

Do that and you're dead.

We slow 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...

- OK. - We should be able to stop it.

Great. Calling her. - PHONE LINE RINGS

You've reached the voicemail for Daniel Geoghan. Leave a message.

Minister, we need that phone line!

OK, let's do this.

Ready? OK?

COMPUTER CHIMES

We regret to inform you that access is denied.

We regret to inform you that access is denied.

Denied.

See it, say it, say it, sort it.

What's happening?

It's a tripwire.

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.

Access denied... - Delayed...

We regret to inform you...

See it, say it, sort it...

GLASSES CLINK

Are you having a drink? - No. No.

SHE SIGHS SHAKILY

Come on.

Ah, no, I-I don't...

You're one of us now.

Quintinshill soon.

What?

Quintinshill.

Worst rail crash in UK history.

230 dead.

Many more injured.

Many, many more.

You really think you can make it?

I'll soon find out.

What about me?

I could've 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.

Alright.

Alright.

How is it possibly alright?

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.

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 massacre.

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.

PHONE 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-I've got a list, the host has

of the people still on board.

Uh, 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-they want to speak to you.

Hello? 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?

TRAIN JUDDERS

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.

Excuse me!

Why?

Because the secretary of state seems so focused on saving her own skin.

She's in a very difficult situation.

What the fuck are we in!

WARNING 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.

WIND WHOOSHES

You're all the same!

And you accept full responsibility for that choice?

I do, ma'am.

WARNING BEEPS

PHONE CHIMES

Nothing by 1:30...

WARNING BEEPS

Excuse me, what's that light for? Sorry.

HEARTBEAT THUDS - DEEP BREATH

OK.

Do you know that Peter's left?

Couldn 't they get him back forjust 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'éléphant dans la pièce.

Don't you?

Yeah, but France doesn't hack French companies, does it?

It hacks us for them, so...

My team is gonna send through everything they can

about something called the Blue Blockade Group, BBG.

Well, uh, I know it, but...

they've never done anything like this before.

No, but our latest Humint 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.

And I know that is not what you want to hear.

WARNING BEEPS

No!

VIDEO GAME NOISES Yes!

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.

If you had Humint, why would you not share it?

We have to protect our sources.

We have to protect each other.

Yes, but if I may...

Abby? Are you there?

Joe!

Where is she going?

Apologies, this is a 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--

I'm not a criminal. I was wrongly charged with a crime.

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 and its own power supply.

Check the bags. Everyone.

About the size of a shoebox.

SOFT CHUCKLE

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, will you stay with Leon

and report straight back to me the moment you have a result?

Yeah.

Ma'am!

Mr Peveril--

Uh...

UPBEAT ROCK MUSIC PLAYS - Woo!

Did you do it?

Did you doubt it?

Send it! - Sent!

MUSIC CONTINUES

Ah!

And with the Heart of Britain's location, in real time.

You're welcome.

Woo!

Yeah!

When I grow up, that's who I want to be.

ABBY SIGHS - MUSIC CONTINUES

What's that?

It's a goods train.

Stopped...

with its engine and half its load straddling the West Coast mainline.

Right, you keep searching here. I'll check the next carriage.

I'll help.

Stop that!

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?

No.

Excuse me?

Gretna 's beyond ourjurisdiction.

You'll need to talk to the control desk down at Manchester.

On it.

Ma'am... that's our train.

No!

Got it!

OK, Manchester, 0161-496-9865.

Direct comms with maybe two thirds of our trains are down.

Do you have a mobile number for the driver, maybe?

I thought we did, but it seems to be out of date.

A name, then? - Um...

Harvey Driscoll.

Pev. - Yeah.

Control, what are the goods on the train?

- Tankers. - Containing?

Natural gas condensate.

OK, thank you.

LINE RINGS - Driver. Already ringing.

Come on, come on!

Come on!

What else have you got?

Abby, what else have we got?

HE GASPS

Abby? Are 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.

PHONE 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.

All trains are currently grounded I'm afraid. - Harvey.

I'm trying to give the control desk-- - I need you to move your train.

I can 't guarantee it. - We've spoken to the control desk.

Look, I-- - Listen.

I've got very little battery.

What's that?

There is another train that's not grounded and it is moving towards you.

Well, stop that then.

CALL DISCONNECTS

We can...

I...

Everyone needs to move down the train now!

Why?

Now. Now. Come on, we're gonna hit something!

Hit what? - That!

Come on!

Estimated time till impact, 90 seconds.

Oh, Jesus!
