[1991, a HYDRA base in a snowy landscape. A man enters a bunker and removes a red book marked with a black star.]

[A technician raises a cylindrical chamber, revealing Bucky Barnes, aka the Winter Soldier.]

[Bucky Barnes is secured in a chair, a mechanical device either side of his head causing him to scream in pain.]

Bucky cringed at the memory and Steve makes sure his best friend was okay. 

Vasily Karpov: [speaking Russian] Желание. Ржавый. Семнадцать. Рассвет. Печь. Девять. Добросердечный. Возвращение на родину. Один. Грузовой вагон. ([subtitled] Longing. Rusted. Seventeen. Daybreak. Furnace. Nine. Benign. Homecoming. One. Freight car.) Доброе утро, Солдат. ([subtitled] Good morning, Soldier.)

[Bucky Hesitates]

Bucky Barnes: Я готов отвечать. ([subtitled] Ready to comply.)

Natasha feels bad for Bucky, cause she knows what it feels like. 

Vasily Karpov: У меня есть для тебя миссия. Санкционируй и Извлекай. Без свидетелей.([subtitled] I have a mission for you. Sanction and extract. No witnesses.)

[Night. A car is driving down a dirt road alone. The Winter Soldier is waiting at the side of the road with his motorcycle. As the car passes, the Winter Soldier follows. He comes alongside the car and disables it. It slams into a tree. The Winter Soldier brings the motorcycle back around and climbs off. He walks to the car trunk and rips it open, revealing a silver case containing several blue packets]

Tony flinches a little and Hadley cuddles up into her father.

[Back at the HYDRA base]

Vasily Karpov: Отлично, Солдат. ([subtitled] Well done, Soldier.)[Marvel Opening Credits]

[Lagos, present day]

[Wanda Maximoff, aka Scarlet Witch, adds sugar to a cup and stirs it. She looks around.]

Steve Rogers: [on radio] All right, what do you see?

Wanda Maximoff: Standard beat cops. Small station. Quiet street. It's a good target.

Steve Rogers: There's an ATM in the south corner, which means . . .

Wanda Maximoff: Cameras.

Steve Rogers: Both cross streets are one way.

Wanda Maximoff: So, compromised escape routes.

Steve Rogers: Means our guy doesn't care about being seen, he isn't afraid to make a mess on the way out. You see that Range Rover halfway up the block?

Wanda Maximoff: Yeah, the red one? It's cute.

[Camera pans to show Natasha sitting two tables from Wanda]

Natasha Romanoff: [on radio] It's also bulletproof, which means private security, which means more guns, which means more headaches for somebody. Probably us.

Holly, Ivanna and Hope snort at Natasha. 

Wanda Maximoff: You guys know I can move things with my mind, right?

Natasha Romanoff: Looking over your shoulder needs to become second nature.

Sam Wilson: Anybody ever tell you you're a little paranoid?

"Only Clint" Natasha states. 

Natasha Romanoff: Not to my face. Why? Did you hear something?

Steve Rogers: Eyes on target, folks. This is the best lead we've had on Rumlow in six months. I don't want to lose him.

Sam Wilson: If he sees us coming that won't be a problem. He kind of hates us.

[A garbage truck is pushing its way through traffic, with no regard to pedestrians or other vehicles]

Steve Rogers: Sam, see that garbage truck? Tag it.

[From the back of Sam's Falcon jet pack, a small drone, launches and flies down to scan the garbage truck.]

Sam Wilson: Give me X-ray.

[weight analysis: Cargo Weight: 13825 kgs. Max capacity.]

Sam Wilson: That truck's loaded for max weight. And the driver's armed.

Natasha Romanoff: It's a battering ram.

"For what" Holly asked 

"I can't remember" Natasha says an Holly smiles at her mother. 

Steve Rogers: Go now.

Wanda Maximoff: What?

Steve Rogers: He's not hitting the police.

[INSTITUTE FOR INFECTIOUS DISEASES]

"Ah right" 

[A man is sitting in the guard station. He looks over as the garbage truck is coming towards the gate. The driver jumps out, and the truck slams into the gateway. Two trucks rush into the compound through the newly-made entrance.]

[Soldiers in black armor emerge from the trucks, firing their rifles around the courtyard. Four soldiers fire gas canisters into the building. Soldiers wearing gas masks enter.]

[Steve arrives and takes out several of the soldiers.]

Steve Rogers: Body armor, AR-15's. I make seven hostiles.

[Sam flies in and up to a rooftop, spinning and using his wings to block gunfire. He takes out two soldiers.]

Sam Wilson: I make 5.

[Wanda arrives and flies over the rooftop and into the courtyard, blocking fire with her powers. She takes control of one soldier and lifts him upward.]

Wanda Maximoff: Sam.

[Sam glides down from the rooftop, catching the soldier on one of his wings.]

Sam Wilson: Four.

The kids smile because Adrian is a lot like his father, being Sam Wilson. 

[Sam's drone flies by, scanning the inside of the building.]

Sam Wilson: Rumlow's on the third floor.

Steve Rogers: Wanda, just like we practiced.

Wanda Maximoff: What about the gas?

Steve Rogers: Get it out.

[Wanda uses her powers to lift Steve up and through the window. He grabs a soldier and pulls off their gas mask]

[Rumlow is inside. He punches down the door. He knocks aside a technician and enters a room with a container labeled "bio-hazard."]

Brock Rumlow: Pack it up.

"Oh shit" Eva said. 

[In another area, Steve is behind a pillar. He throws his shield, and it bounces off the soldier and back to Steve. Meanwhile, Wanda is now using her powers to remove the gas from the building. Sam is exchanging fire with several soldiers.]

[Rumlow walks outside onto a balcony and sees that Steve's team is here.]

Brock Rumlow: He's here.

[Inside the building, Steve sees the vial missing.]

Steve Rogers: Rumlow has a biological weapon.

[Natasha is riding in on a motorcycle.]

Natasha Romanoff: (on radio) I'm on it.

[She jumps off the motorcycle and it skids toward a soldier. She takes out soldiers through hand-to-hand combat. Rumlow comes up behind her and grabs her collar, dragging her onto an armored vehicle. She electrocutes him.]

James looks at Natasha a way which made Lily hit him over the head.

Brock Rumlow: I don't work like that no more.

[He throws her through the roof hatch into an armored vehicle, drops in a grenade, and shuts the hatch.]

Brock Rumlow: Fire in the hole.

Mercenary: No!

[Natasha takes out the soldiers inside, then grabs one to shield herself from the grenade. The doors blow open and she is thrown out.]

"Are you okay" Holly asked in Russian.

"Yeah baby, I am" Natasha replied softly. 

[Steve runs out onto the balcony and spots Rumlow.]

Steve Rogers: Sam. He's in an AFV heading north.

[Inside the AFV, Rumlow secures the biological weapon and hands it to a soldier.]

Brock Rumlow: Take this to the airstrip. We're not gonna outrun them. Lose the truck.
[The truck crashes into a nearby structure and Rumlow and the soldiers emerge.]

Mercenary #1: Where are you going to meet us?

Brock Rumlow: I'm not.

[Sam lands on the roof of a structure. He scans the area with his goggles.]

Sam Wilson: I got four, they're splitting up.

[Natasha rides through the crowd, back on her motorcycle. She abandons it again and runs across the hoods of cars, in pursuit.]

Natasha Romanoff: I got the two on the left.

[Steve is also running across cars. He spots a vest in the middle of a crowd.]

Steve Rogers: They ditched their gear. It's a shell game now. One of them has the payload.

[Someone throws a bomb at Steve. It sticks on his shield. Steve throws it in the air and the bomb detonates safely away from citizens. Rumlow comes up behind Steve and punches him in the back.]

Brock Rumlow: There you are, you son of a bitch. I've been waiting for this!

[Meanwhile, Sam is still chasing the other mercenaries. Sam flies up and takes out his two, then searches their bags for the payload.]

Sam Wilson: He doesn't have it. I'm empty.

[Natasha is chasing the soldiers through the crowd.]

Natasha Romanoff: Out of the way!

[She tackles one soldier and engages him in combat. When the other soldier arrives, she hurls a basket at him to distract him. She uses her skills to fight them and ends up face-to-face with one soldier. They point their guns at each other. A moment passes. Then, the other soldier produces the vial.]

Mercenary #1: Drop it. Or I'll drop this. Drop it!

Mercenary #2: He'll do it!

[Redwing descends and fires at the soldier with the vial. He drops, and in the moment of distraction, Natasha fires at the other soldier, then catches the falling vial.]

Natasha Romanoff: Payload secure. Thanks, Sam.

Sam Wilson: Don't thank me.

Natasha Romanoff: I'm... not thanking that thing.

Ivanna smiles at her mother's antics and Clint hits his wife on the arm sarcastically.

Sam Wilson: His name is Redwing.

Natasha Romanoff: I'm still not thanking it.

Sam Wilson: He's cute. Go ahead, pet him.

[Steve and Rumlow are still fighting, neither one seeming to have the upper hand.]

Brock Rumlow: Come on!

[Rumlow pins Steve to a building and extends a blade from one of his gauntlets.]

Brock Rumlow: This is for dropping a building on my face.

[Steve grabs Rumlow's arm and pulls the gauntlet off, only for Rumlow to reveal another knife. But Steve bests him. Defeated, on his knees, Rumlow removes his mask, revealing a scarred face.]

Brock Rumlow: I think I look pretty good, all things considered.

Steve Rogers: Who's your buyer?

Brock Rumlow: You know, he knew you. You pal, your buddy, you're Bucky.

Steve Rogers: What did you say?

"Nice to know you care" Bucky says 

Brock Rumlow: He remembered you. I was there. He got all weepy about it. Till they put his brain back in a blender. He wanted you to know something. He said to me, "Please tell Rogers. When you gotta go, you gotta go." And you're coming with me.

[He activates his bomb vest and Steve flinches as Rumlow's armor ignites, but Wanda keeps the blast contained around Rumlow who grimaces in agony. She lifts him into the air before she loses control, and the explosion finally blossoms, devastating entire floors of a nearby office building. Wanda sees what happened and is scared by it.]

The kids knew that Kendall felt like that sometimes when it came to using her powers.

Steve Rogers: Oh my . . . [Steve stares up.] Sam . . . We need . . . Fire and Rescue . . . on the south side of the building. We gotta get up there
