Trigger Point

A bomb delivered by a drone destroyed a transformer

at the Isle of Dogs Power Station.

The person we believe to be the drone pilot

is now in custody.

Take one more step and I'll shoot!

His name is Nicholas Hood.

You found out that Johansson was having an affair.

You rigged his lover to a collar bomb.

Sorry, just stay still for me, please.

Lana!

Nick, you messed this one up.

I don't recognise your laws.

Everything all right with Mum?

She won't talk.

People deal with grief differently, Dad.

Well, maybe you could help.

I'm all in.

Tell me what you want me to do.

We will.

What's that?

Insurance.

I love you and I would love to make it work.

Yeah, me too.

The ITN Switchboard got a call 25 minutes ago

saying there was a device inside one the lifts.

Expo-2, we've got a jammer.

All clear.

Explosion in one of the lift shafts.

Where's the nearest access point?

Up here.

What?

Who's the officer killed?

Well...

When will you release the name?

Can you give me any more information about the suspect?

Any other persons of interest?

Look, anything at all I can use.

Martina.

I'll call you back.

In the light of last night's events,

I'm now taking direct charge of this investigation.

Thom was an outstanding officer,

dedicated, hardworking, liked by all.

The best thing we can do,

the only thing we can do to honour his memory

is to catch whoever did this.

They're still out there.

They've taken one of our own.

This is personal now.

It's our fight and we will win.

Erm, plate's hot.

Oh, thanks.

Can I get a black coffee please?

Yeah, sure.

Thank you.

That looks good.

What is it?

Um, er, Chilaquiles?

Er, it's basically, erm, corn tortilla pieces fried,

salsa, cheese, eggs, and beans.

I come here every morning,

have exactly the same thing, it's...

It's delicious.

Well, it looks it.

Try a bit.

Oh.

No, I can't.

Go on, go on.

It's the perfect start to the day.

All right.

So what, do I just get...

Proper bit with cheese.

Get some of the beans, too.

Okay.

Hm?

Mm!

What do you think?

That's amazing.

The working assumption is that these attacks are linked,

though the targets appear to be radically different.

Last night's explosion took place in the data server room

of Tratea Global Analytics.

It's a data mining company.

It's been accused of obtaining

and using personal data illegally.

Now, let's get some answers.

What kind of data do they hold?

Why would terrorists target this particular company?

Is there a connection with the power station?

And Thom, how did he fall?

What were his movements just before his death?

He was on the stairs, sir.

He was taking passengers from the lift to the ground floor

when the bomb went off.

He must have gone back up.

Any CCTV?

Erm, the team are processing that now, sir.

We should have collected all pertinent materials

within the hour.

But, erm, this is what we've got so far.

Yeah.

So, thought I'd do the same here.

A man of habits.

Right, I'd better go.

I'll be late for work.

Oh, that's a shame, I was, erm,

well, I was enjoying our chat.

Well, we could, erm, continue another time,

if you'd like.

Yeah.

Yeah, maybe.

Tonight?

Mm.

Look, Why don't you, er, give me your number?

I lost my phone.

I'll email you.

Give me your address.

Right.

Oliver.

And you are?

Hope.

I didn't realise you were so important, Oliver.

Ah, tell my boss that.

Don't forget your bag.

Oh, yeah.

Er, thanks.

Erm, see you later.

Looking forward to it.

Morning.

Morning.

Helen.

Yeah?

Just can't believe it.

You two were perfect together.

You okay?

Mm.

Looking for those that've got jam inside.

They're nice.

Dad, I can't really talk right now.

Yeah, I'm sorry to bother you at work, luv.

I was just wondering if you've managed to speak to Mum.

Yeah, well I called her.

She just didn't call me back.

Look, can you try her again for me, please, luv?

You know, when you've a minute.

Okay, I'll text her.

I'll tell her I'll come round tonight.

All right, thanks, luv.

I've got to go.

Re...

So, I've just briefed the Home Secretary.

She's offering us whatever resources we require.

Money, additional manpower, but we have to deliver.

Batra, run us through how the terrorists got

a bomb into the building.

Yeah.

Er, a fault was reported on the lift.

An engineer was called in,

but his vehicle was stolen

and he's since been reported missing.

So the terrorists used his pass

to gain access to both the building and the lift.

Er, according to the log,

he left the building shortly before the explosion and

we're using ANPR to track the movement of the stolen van.

There was a call that came in about 20 minutes ago.

Er, the caller used voice altering software

and he claims to have vital intelligence on the group.

Prank call?

I don't think so.

He knew detailed information about how the CCTV

at the power station was hacked.

He wants to meet.

Can we contact him?

He didn't give us his number,

we couldn't trace the call,

but he said he's gonna call us back.

Okay, good.

And what about Nick Hood?

Well, he's wiped his life clean.

There's nothing in his flat.

No photos, there's nothing.

Social media?

He has none.

But we're using facial recognition to download pictures

from other profiles.

Er, graduation photos, Hood and his colleagues

at a symposium and that kind of thing.

We're talking to the security services

to see if anyone in the photos are on a watch list.

We did turn up one thing, sir.

Immigration and travel manifests show

that he flew to Poland a year ago.

He played in the Krakow Chess Open

and the tournament organisers confirmed

that he played the first day

and then he just didn't attend for the rest of the week.

And then UK Border Force say that he then re-entered the UK

through Dover like a week later.

Our team has ascertained that the TNT
