Original subtitles

There's this guy, and I think I kinda like him.

You want a ride?

- Chief Cranston. - Chief Pascal.

How long have we known each other?

30, 35 years?

Unfortunately, today's hearing

is gonna need to be postponed.

Chief Cranston collapsed on the scene.

- Was it a heart attack? - He didn't make it.

SkyWest four-niner-Alpha, reduce speed to 2-1-0.

You're following a heavy 7-5-7.

Twelve o'clock, eight miles.

Gateway Tower, Chicago Center.

Go ahead, Center.

You talking to Dominion 63?

Stand by.

Chicago Center, what have you got on your end?

We lost their beacon. Transponder just dropped.

We got skin paint only.

Dominion 63, if you read, ident.

I'll try them on guard.

Dominion 63, Chicago Center on 121.5... radio check.

- What's up? - Uh, Dominion 63.

We lost comms and transponder at the same time.

Just went quiet.

We need to clear the airspace all the way to Gateway.

Alert ground emergency services.

And do not take your eyes off that aircraft.

This is Jackson, Chicago Center.

Yeah, we have a situation here.

City flags are flying at half-staff today

as Chicago honors Deputy District Chief

Alexander Cranston.

Chief Cranston rose through the ranks

after distinguishing himself during the infamous

Heart of Chicago Fire in 2001.

He was credited with leading half a dozen civilians

to safety, actions that earned him

the department's highest commendations.

Pascal.

Yes, sir. I'll be right down.

Still tracking inbound.

Heading 2-7-0.

It's been 22 minutes since last transmission.

Feds have been alerted.

They're running the passenger manifest now.

Jackson. They're here.

Darren Jackson. Operations Supervisor.

Special Agent Upton. FBI.

Tell me everything we know. Start at the beginning.

I thought Pascal was coming over.

No, he got called in downtown.

Sounded urgent.

Whoa, check this one out.

Damn, I didn't realize

Pascal and Cranston went back that far.

The chief must be pretty broken up.

Yeah, well, at least Cranston's getting

the send-off he deserves.

It's just... it's just so hard to believe this could happen.

He was a great man, Joanie.

Hell of a firefighter.

Thanks for being here, Hank.

I knew all his CFD colleagues would come pitch in.

But to see so many cops show up too?

It's a huge loss for the whole city.

- Mom. - Excuse me.

Yes, sir, that's what I'm saying.

Omar Bengoa is on this flight.

Okay, good. I'm glad we're on the same page.

I'm heading out there now.

All right, everybody, listen up.

Are you the CFD liaison?

Chief Pascal. Battalion 25.

- Hailey Upton. - What's the situation?

We have a commercial aircraft that's gone dark

over Lake Michigan without warning or explanation.

Radar's showing it's still airborne,

but the pilot and copilot stopped responding

32 minutes ago.

No distress signal.

No reports of mechanical failure.

Just radio silence.

Why is the FBI involved?

You think it's a hijacking?

It's impossible to say what's happening up there.

All we know is, it's headed right for Chicago.

It's just, the first post-breakup run-in

is always so awkward.

I'm sure it'll be fine.

You're both adults.

And remember, you survived an entire shift

in the ambo with your ex-fiancé.

Little small talk with Frost, you can handle it.

You are totally right.

Damn, I, uh, left my phone in my locker.

Hey.

Um...

I know that look.

What look?

It's the old "we can't do that again" look.

It was an awesome night.

I had a...

I had a great time.

Seriously, it's just that...

Look, I get it.

Yeah, you don't need to explain yourself.

It was a one-time deal.

Anything more than that, it gets complicated, right?

Mm-hmm.

It's all good.

The other thing is...

Oh, yeah, yeah, yeah, it's in the vault.

Squad 3, Truck 81, Ambulance 61,

airfield emergency response.

Airfield emergency?

Descent looks stable, like they're riding the arrival.

Are they configured?

Affirmative. Looks like full approach.

They're flying a clean approach

without talking to anyone?

Maybe something happened at cruise

and automation's bringing them home.

Does Dominion have cabin video?

If it does, it's not transmitting.

The hell is all this?

I don't know, but it must be serious

to bring this whole circus out here.

Pretty badass, huh, Lieutenant?

This one's never been to an air incident before.

But don't worry, I'll keep him out of trouble.

Don't believe her, Lieutenant.

I've seen way more action than her.

Don't get your hopes up.

It's probably just a precautionary detail.

But stay sharp anyway.

- Always. - You got it, Lieutenant.

Lieutenant Severide,

Lieutenant McHolland, this is Special Agent...

- Hailey Upton. - Hey.

Special agent? Moving up in the world.

I'm not alone, I see, Lieutenant.

Hailey Upton.

I thought you were in Detroit now.

What brings you back home?

Dominion Airlines Flight 63.

Originated in Toronto, 182 passengers,

six crew members onboard.

ATC lost contact just under an hour ago.

It's been radio silence ever since.

Any idea what's happening with it now?

No.

They've maintained the same flight path, though,

so we're thinking it's probably not a hijack.

If they've lost avionics and they're coming in

on full autopilot, the chances of them

having a clean landing are...

well, that's why you guys are here.

All right, let's get into position.

Engine 40, Truck 81, east side of the runway.

- Copy! - Engine 67, Truck 68,

take the west side of the runway.

Prep the deck guns for foam.

Mikami, prep for triage. - Copy.

Gateway Tower, you got a visual?

Affirmative.

Landing gear appears to be down.

They're 3 north of the field.

Any movement in the cockpit?

That's a negative.

Touch down.

Reverse thrust.

Spoilers deployed.

Speed reducing.

Anyone see any pilots?

It's so quiet.

Is that a good thing or a bad thing?

Chicago Center, this is Jackson.

That's a negative, Agent Upton.

Gateway Tower's got nothing.

Tower still hasn't made contact.

No visual on the pilots.

I say we breach.

If it's a hostage situation,

things could go sideways real quick.

Well, what's your gut say?

You think it's a hostage situation?

Let's breach. We have snipers on overwatch.

Let's do it.

We're authorized for forcible entry.

Engine 40, Engine 67... - All right, let's move.

Flank the aircraft and keep a 50-foot perimeter.

Stand by with the deck gun and two charged lines.

Truck 68, Truck 81, take position

underneath the forward and rear doors.

Throw your sticks flat. - Copy, Chief.

I want everyone buttoned and bottled.

Keep your eyes peeled.

We have no idea what we're dealing with here.

Cruz, Capp, you guys take the lead on the forward door.

I'll try the exit over the wing.

Copy.

Truck 81, I'm gonna need a 10-foot by the wing.

Copy.

All right, Herrmann, throw the aerial.

Ballard, grab the K12.

Vasquez, you're with me.

all: Copy. - Briggs.

Squad will take over on breach.

Could use two of yours for backup.

- I can go, Lieutenant. - Me too.

All right, you two are with Squad.

Let's go. Watch your step. Walk slowly.

Up.

Hey, be careful. - Yeah.

We're gonna have to cut through the locking pins.

K12. - Copy.

All right, Chief.

We're through the locking pins.

Pop it.

On it. Mask up.

Good?

- Good. - I'm good.

Cruz, everything all right?

Yeah, Chief. We're going in.

You got that 4-gas meter, right?

- Yeah. - Stay on my hip.

Yes, sir.

Okay, come on.

Oh, my God.

What is it?

Hey, Cruz, what's the situation in there?

They're dead.

They're all dead.

They must have...

I think we got a hazmat situation in here, Chief.

Emergency. All firefighters

evacuate the plane right now, immediately.

Go, go, go. We gotta get out of here.

- Get out. Off the plane. - Right now. Let's go.

Engine 40, Truck 81, set up for decon.

Copy.

Macy. Macy, come on! We gotta get out of here!

Right now! Let's go!

We've got a mass casualty incident.

Hazmat likely. - No, sir.

Nothing's confirmed yet.

All we know for sure is we have over 100 casualties...

All units, back away from the aircraft.

We're setting a 100-foot perimeter.

Engine 40, set up a decon corridor right away.

Hey, Chief.

We should go and check for survivors right now.

Hazmat 2's eight minutes out.

Squad's level B suit is good enough for primary search.

Give me two minutes.

Just too many unknowns right now.

There's 188 people on that plane.

If anyone's still alive, they don't have eight minutes.

Cruz, what the hell happened in there, man?

20 years on the job,

I've never seen anything like that.

Your heart rate's elevated.

Do you feel lightheaded at all?

No.

Okay.

I'm just cold.

It's just...

I would be shook up too, Mace.

It's normal.

How we doing, Cruz?

All units, be advised, Hazmat 2 is on scene.

What are we looking at, Chief?

A plane full of casualties.

Probably all fatalities.

Cause is still unknown.

Hey, that was Dominion's head of security.

The airline began installing cabin video recording devices

onboard all their planes a few months ago.

Think it'll tell us anything about what happened up there?

Nobody's seen it yet.

It's on a drive onboard the plane.

Severide, progress report?

Severide, progress report.

Severide, come in.

Uh...

not good, Chief.

Whatever got all these people,

it must have happened scary fast.

It's like no one had any time to react.

My 4-gas readings are still negative.

No CO, no H2S,

no industrial hits of any kind.

Any chance it's biological?

No, I think it's chemical, it's just...

I don't know what the hell

kind of chemical behaves like this.

The airline says there's

a recording device in the cabin.

Could help us piece things together.

Footage is stored on a hard drive in the overhead bin.

A side of the aisle.

First overhead cabin, A side, copy.

I'm on it.

Got it, Chief.

Hey!

I got a survivor, Chief!

- Help! - I got a survivor, Chief!

What?

Oh, my God.

Got her.

Wait, she's pregnant.

She is. We gotta move fast.

Man, lungs are wet. I hear rales.

She's barely moving air.

Oxygen's 84. Heart rate is low.

Strong fetal heartbeat.

I'm gonna tube her. - Okay.

Okay. Let's give her atropine.

- Atropine... - In the nerve agent kit.

Is that what we think this is?

I don't know, but we gotta treat it like it is.

Atropine's in.

- All right, I'm in. - Okay.

Okay, let's run fluids, and I'll get us out of here.

Okay.

I know it's not a combustion event or a sewage leak,

but that's all I can rule out until my hazmat team

gets onboard with more sensitive equipment.

Not gonna happen, Chief.

Dominic Pascal.

Nathan Conway, Weapons of Mass Destruction

Coordinator for the Chicago Field Office.

The WMD Directorate is formally

assuming command of this incident,

which means all field operations

now go through me, including CFD.

Well, understood.

As I was telling agent Upton, it's critical

that I get my hazmat team onboard so that...

The FBI's hazardous materials response team

always goes in first, Chief.

No exceptions.

Now, once we process the scene,

then we can have a... - Chief.

What is this?

I've authorized my Squad lieutenant

to go onboard... in a level B suit, of course.

He recovered one survivor and the hard drive

from the plane's cabin video recording system.

- Can you pull this up? - Yep.

Scrub forward. They lost contact at 8:07.

Wait, go back.

There, on the left side of the aisle,

see if you can zoom in.

Get me the director on a secure line.

And reach out to DHS and DoD and let them know

there's been a chemical weapon attack in Chicago.

Terrorism likely.

And we need to loop the media in

before the story starts spreading on social media,

so find us a spot for a briefing.

Sir, maybe we should wait for the hazmat team

to do a full sweep before we publicly

start calling it a terrorist attack.

I'm sorry. Who are you again?

This is Special Agent Upton,

Detroit Field Office.

She was working the HIDTA Task Force case

that led us to this flight.

Thank you for your assistance, Agent Upton.

We'll take it from here. - With all due respect, sir,

we were tracking a suspected narco courier,

not a terrorist, and he could be the one in that video.

Then you know there's always been significant bleed over

between the traffickers and the terrorists,

going all the way back to the Taliban.

I'm very well aware that.

We've got 200 bodies on that plane,

so it's safe to say this is no longer

a narco trafficking case.

Wouldn't you agree?

Couldn't say that for sure, sir.

Your prior knowledge of a subject may be useful.

But if I'm going to keep you on this investigation,

then you need to understand,

this is now a counterterrorism case.

Are we clear?

Yes, sir.

Good.

Start by ID'ing the passenger in 5D.

If that is your guy, then see what you can turn up.

He obviously didn't do this alone.

Her sats are dropping!

She's down to 85, and she's not compensating.

Still not getting enough oxygen.

I think she needs suctioning.

What the hell is this?

U.S. Marshals!

Do not roll your window down.

We're executing WMD response protocols under ESF-8.

I need you to stay in your vehicle.

Keep your doors closed.

Keep your windows up.

Stand by for further instructions.

What the hell did they find on that plane?

Hey, Upton.

Passenger in 5D, was that your guy?

Yeah.

His name was Omar Bengoa.

He was a legendary smuggler in the narco world.

Drug smuggler turned terrorist?

I know. It doesn't add up.

Drug traffickers don't just decide

to become terrorists all of a sudden.

So what the hell happened up there?

I don't know.

We got a bunch of conflicting data,

all leading in different directions.

The WMD guys are so locked onto this

international terrorist angle, I'm worried

they're gonna miss something.

What are you guys gonna do about it?

I'm gonna follow the only lead I got,

which is going to Bengoa's apartment.

I doubt there's gonna be anything there,

but right now, I gotta take my orders from Conway.

We don't.

If there's something we can do, you let us know.

Hey, where are you?

Hey, we're in the ambo outside of Med.

There are armed U.S. Marshals out here.

They're not letting us in.

What's going on over there?

The FBI's calling it a chemical weapon attack.

They're implementing some kind of emergency protocol

so they can figure out exactly what it was.

Okay, well, that explains that.

How's Novak holding up?

Uh, she's doing okay.

Our patient's critical, though.

All right, I'll try to figure out whatever I can

and let you know.

Hey, Vi, hang in there.

Thanks.

They sent a platoon to guard two paramedics

and one unconscious patient? - Yeah.

I don't get what kind of chemical agent

would elicit such an extreme response.

Well, the news is seriously implying

that it's a terrorist attack.

Let's hope to God it's some old school nerve agent

like Sarin and not something worse.

Hey, Chief. What are you hearing?

As a matter of fact, one of my doctors was

Army Special Forces in a previous life.

Yeah, it might be just what you're looking for.

FBI! We got a warrant!

Kitchen's clear.

- Clear. - Bedroom's clear.

There's two-day-old takeout in here.

Plenty of groceries.

He was planning to come back.

So what were two Detroit agents doing

working a case in Chicago, anyway?

We have this policy in our office...

we try not to predict where the facts are gonna take us.

Hey. Check this out.

Not sure how you get something like this

through a TSA screening.

Oh, we can run down the manufacturer,

see if we can ID any potential accomplices.

Speaking of accomplices.

You recognize him?

No.

It's probably too grainy for facial recognition.

Well, upload it into NGI anyway, see if we get a hit.

I knew this place would fall apart without me.

Hey.

Sorry to drop in unannounced.

What are you doing here?

I'm on a drug enforcement task force.

I got a tip about a big meth operation out here.

You don't trust the Chicago Field Office to work it?

No, it's not that. Um...

a couple weeks ago, I heard chatter

on a tapped line about an American trafficker

who got made as a U.S. military operative

in Bolivia.

Halstead.

- Yeah. - Huh.

I was worried if I tried to warn him that

I'd be putting him in danger.

So I decided to start working the case myself.

And?

It led me to a local drug mule

named Omar Bengoa.

Turns out, he was trying to smuggle in

some precursor chemical for some high potency meth cook.

He was due to arrive here today on Dominion Flight 63.

You know, they're saying that was a terrorist attack,

some kind of chemical weapon.

So is it just a coincidence

that your mule was on that same flight?

I don't think so.

They have to be connected.

So what?

This meth precursor story is just a smokescreen?

I'm not sure yet.

Our hazmat team has been scrubbing that plane for hours.

They still can't ID what it was that killed all those people.

And the WMD director has got agents searching

from Canada to Pakistan to try to figure out

who Bengoa was working for.

They're convinced it's an international operation.

- But you don't see it? - No.

My gut's telling me something else is going on.

Good.

Whoever's behind this, they used a local operative

through local channels for a reason.

Just tell me what you need.

You could warn Halstead, for starters.

And maybe he knows something we don't.

He's been onto Bengoa before I was.

Hailey, if your hunch is right

and this incident really was homegrown,

we need to mobilize every resource we got

on the streets of Chicago.

I couldn't agree more.

What do you got?

All right, I'm on my way.

I'm gonna head to the morgue

and see what the ME knows about the chemical.

Let's keep each other posted.

You got it.

Hey, heart rate and sats are crashing.

I can't tell if she's having a seizure or a contraction.

Uh, check for crowning and grab midazolam.

Okay.

Hey, hey, easy.

You're in an ambulance, ma'am.

Oh! Damn it.

I'm coming back there.

I need you to stay put, ma'am.

We have a critical patient back there!

We're under strict orders.

It's okay. Hey, hey.

Hey. Hey, hey.

You're okay.

Novak, you've got blood on your face.

You gotta decon yourself.

Okay.

Ambulance 61 to Main.

Our patient just seized and is going into active labor.

We have to get her inside now.

What is the status?

We'll let everyone know, Ambo 61.

Continue to stand by.

That was Violet Mikami.

We have a patient and a baby who are going to die

on our front door if we don't do something.

Well, what do you propose, Dr. Asher?

The Feds won't let them get out of the ambo.

But nobody said that we can't go in.

Uh, hell no.

Hell no. That's out of the question.

If that woman dies...

We have no idea what she was exposed to,

no idea how to even weigh the risks of going in.

I will be in full PPE.

I agree with Dr. Archer.

We have to give this a little more time.

Let them figure out exactly what we're dealing with here.

Fine.

Hey, what's up?

Dr. Lenox is here.

Hey.

You all right?

It's okay if you're not.

Uh, this one's hitting me pretty hard.

All those people.

And that woman.

I know.

It's horrific.

We're gonna find whoever did this.

It's like a combination of these three.

But there are also passengers with these rust-colored streaks

down their faces too.

It makes me wonder if it wasn't some

novel cocktail of toxins,

which would radically complicate the situation.

It would explain why the FBI hasn't

ID'd the chemical, though, right?

Yeah.

What's your read on the risk of secondary contamination?

I'm not gonna sugarcoat it.

It would be pretty stupid to rule it out.

What's the news, Agent Upton?

Was Severide able to connect with Dr. Lenox?

Yeah, she's here with us.

You're on speakerphone.

Yeah, this is Lenox.

Uh, unfortunately, the symptoms Severide is describing

don't really line up with any chemical exposure

I've ever encountered.

Have you ever heard of methyl-propiophenoxide,

by any chance?

No, I haven't. Why?

Did the FBI find traces of it on the plane?

No, it's just a theory.

But I could use your expertise on it.

It's a madhouse in here.

Agent Upton?

Yeah.

Medical examiner is expecting you.

Sorry, we've never had to process

this many bodies at once.

Had to call in pathologists from four other counties.

You'll have to put those on.

It's Dr. Woodward at station four.

A methylated propiophenone

would definitely cause rapid tissue penetration.

It would also be highly reactive,

meaning it wouldn't be stable in the bloodstream.

That would explain the negative tox report.

Correct. It's a decent candidate,

but my gut says methyl-propiophenoxide is

a precursor or a byproduct, not the main event.

Hopefully the mass spectrometry lab

will shed some light on it.

How long till we get those results?

Well, we put a rush on it,

but you can only speed up the process so much.

Excuse me.

I said excuse me, sir.

What are you doing over there?

I'm just... just checking the abdominal cavity.

Why didn't you start with a Y-incision?

Stop what you're doing, please,

and let me see your credentials right now.

Yeah. Yeah, sure.

Okay, yeah.

I got a badge over here.

Let me find it.

That's an emergency containment door.

Only the fire department can open it.

Go outside! Call 911!

Tell them there are people trapped in here!

Severide! Help is on the way!

Everybody get down!

Stay as low as you can.

Squad 3 to Main, do you copy?

Squad 3 to Main, do you copy?

Everybody stay calm.

I'll try to hold it back with an extinguisher

until help arrives.

There's one against the wall!

Squad 3, Truck 81, structure fire, 2112...

- That's the county morgue. - Yeah.

That's where they took all the bodies

from the plane, right?

Yeah, that's where Kelly was headed.

We're gonna have to find another exit!

All the exits are locked down

because of the emergency containment system.

All right, we're gonna have to go through the vent.

What can I do?

Lenox, grab the extinguisher. Keep the flames back.

Stay low.

Gonna have to find something to pry up the grate.

Try this, try this, try this.

Squad's ten minutes out, Chief.

Truck, take primary search.

There's reports of civilians trapped in the autopsy room.

Copy that.

Engine 40, connect to the standpipe system.

- Copy. - Truck, let's move.

Autopsy room is in the basement.

Let's go.

All right, let's move! Let's move! Go!

Go, this way!

Stay down. Keep moving.

Go through.

Get her out.

- Help me grab this table. - Okay.

Ready? - One, two.

All right, go for it.

I'm right here. Stay with me.

Stay with me.

Herrmann, There's the manual override.

I got nothing!

We're gonna have to force it.

Vasquez, go get the StrongArm! - Copy.

Ballard!

Strike, strike!

Strike, strike!

Pull!

Again!

What's happening?

- Whoa, whoa, whoa. - I'm gonna die!

Keep this on.

I'm gonna die.

Slow your breathing.

You're gonna be okay.

- Coming in! - Move!

Kelly!

Kelly.

All right, let's go!

One at a time! Move! Let's go!

Gotta move!

Come on. Keep going.

All the way out the back.

Stay low.

FBI! Stop!

Drop that weapon!

Now!
