In part of the London Underground, a great light is suddenly emitted. Bison is then seen rolling down a track, using his magnetic powers to move. But suddenly he gets blasted.

A special forces team -consisting of Rory, Burke and Celia -arrive and tells Bison to put his hands where they can see them. Bison says with pleasure, and is about to use his powers again when Celica tells him to look behind. Bison scoffs at her, only to find that there really is something behind him: a train. He is just about able to leap over it.

However the team is able to arrest him. Burke says they've got him, to which Bison says it's not an inconsiderable accomplishment -but of course the real trick is to hold him.

The Street Fighters watch a news report about Bison's arrest. Escher says that the trouble is, Scotland Yard has no idea what they're holding. Bison is a time bomb, and his people will never let him remain behind bars. If there is a jailbreak, many innocent bystanders could be caught in the crossfire. He's sending Guile and Cammy to London, to make sure that doesn't happen. Honda and Dee Jay are going to rendezvous with them there.

Cammy asks if he's certain they need to be there, but he asks her if she has a problem. She says that she knows the ones who bagged Bison, and they're the best in the game -next to the Street Fighters, that is. She's not happy about having to maintain cover around her old chums. Escher tells them that their cover will be as hired security for a private US trade delegation... which sells plumbing supplies. Cammy says it's back to London again.

At Scotland Yard, Burke's team want to go to a pub, but Burke is still working on the arrest report for Bison. As Celia and Rory start to leave, the power goes out. Burke's report, which he'd spent four hours on, is lost. He decides to finish it up in the morning, and leaves with his team.

The pub the team head to is devoid of anyone else, as Rory gives a victory speech to nobody. He tries playing darts instead, and does so by loading the darts into one of his mechanical hands, and firing them into the board.

Burke then says that they have an early roll call in the morning, and wants to leave. Celica says he can't leave yet, as the party has just started. He apologizes but says he just doesn't feel like celebrating. She tells him he never feels like celebrating, not any more... not since she left. He tells her she keeps bringing her up, not himself. But then one of the darts hits their table, as a voice asks if this is a private game, or can anybody play?

It's Cammy, who tells them she thought they'd forgotten her. Rory hugs her and says they could never forget her, but Cammy says she still needs her ribs! He releases her, as Burke tells her that it's good to see her again. She tells them that she's missed them all, but she's here on business.

Burke says she must have come back to rejoin the team, to work with him -them -again. Cammy explains that she's actually on a security detail for a stateside trade group. Celia asks if it's for arms dealers, but Cammy has to embarrassingly admit that it's for plumbing supplies. Burke asks her if she left special forces so she could play nurse maid to a bunch of plumbers, but she says she left because she didn't fit in. All the rules, all the office politics and drama... and all the personal fun and games, does he remember the fun and games? Burke says it was never a game for him. What she and he had back then was...

Before he can finish, Guile walks in. Cammy introduces him but Burke is surprised she left them for this guy. He's heard Guile got drummed out of the service when he got himself court marshaled for going past his operations mandate in Shadaloo. He must have wanted Bison pretty badly, to which Rory reminds him that they just caught Bison. Cammy tells Guile they should go, and thinks coming her was a big mistake.

Rory then says he can hear someone outside. The group head out and see a guy climbing up one of the pub's walls, so Guile starts climbing after him. He tells Cammy to secure the building and then meet him on top.

Burke tells his team to head to the top, so Rory fires a grappling hook from out of his wrist, and takes Celica with him. As they head up, Celia admits that whilst Guile may not be regulation, he's not bad. Cammy uses a scanner and finds out that the whole building has been rigged with explosives -it's going to blow!

Guile, Celia and Rory stop the intruder on the top of the building, but suddenly a helicopter appears. It drops down a rope ladder and the intruder climbs it, and they can't do anything due to the helicopter firing lasers at them.

Cammy wants to get up there and warn Guile, but Burke warns her that she doesn't know if there is time, so she can't go in there. She knows the protocol, but Cammy says she knows his protocol, that's why she quit. But then the pub explodes, sending them both flying back. They're both alright and get up, but see that the pub is being rocked with multiple explosions.

On the roof, Guile tells the others to follow him. He throws a sonic boom at the support struts for a billboard, which breaks them.

They then use the billboard to surf their way off the roof, and onto the street below. Celia tells Guile that was a splendid move, and she and Rory owe him one.

He tells her that nobody owes him anything except an explanation, but he thinks he already knows the answer. Does the name "Bison" ring any bells? The group return to Scotland Yard, where Burke's team are briefed on the new situation. There have been a series of explosions at schools and shops all over London, fortunately because of the time these have been happening, no one was injured. Bison is taking credit for the blasts, and has said his people will cause more of them today unless he is immediately granted his freedom and given one billion pounds sterling.

Cammy and Guile haven't been invited to the meeting, and have to wait outside. Cammy tells him this is why she left, as they all sit around fiddling whilst Rome burns -and Burke is the worst of all, him and his precious protocol. Guile contacts Honda and Dee Jay, who are flying above London in a helicopter.

Dee Jay says that Honda is already working on breaking the special force's communications codes, but Honda says it may take a while. Guile tells Cammy that a little reconnaissance may be in order, as they could do with more information. Cammy says that's her specialty, and goes to ask the admin guy at the front desk. She asks him if he really believes M. Bison is behind the explosions, to which he says he thinks so. Although it makes no sense to him, as if Bison's chaps intend to break him out, why do something guaranteed to triple security?

Guile comes up and says maybe they just don't care how much security there is. They then see a large guy walk by, and Guile asks who that is. The guy says it's Bison's lawyer, but Guile and Cammy realize it's Zangief.

The two chase after him, but they see him race away in a car. Guile contacts Dee Jay and gives him the car's details, and Dee Jay tracks it for them. Zangief stops at an Underground entrance, and heads down the steps.

Guile and Cammy see his car, but there's no sign of Zangief himself. Guile thinks he must have gone inside, and also head down the steps. They arrive just in time to see Zangief board a train, which begins to move off.

Cammy grabs Guile, as Guile grabs onto the train. They're able to get inside it, and start searching for Zangief...

...but they don't have any luck. Guile says they warned her special forces people about Bison, and how they should have sat on him hard until he stood trial, but they still messed this up. Cammy snaps back by saying her people did the best they could -don't forget that they caught Bison in the first place. Guile tells her they also let Zangief get in there to plant a billion dollar clambake.

Dee Jay then contacts Guile and says that the deadline has passed. However Downing Street didn't give in, as they think Bison is bluffing. But Honda thinks that what Bison has planned, it'll be soon, and it'll be big.

Cammy says they've got a problem. They are on a train on the Channel Tunnel, which won't stop until they arrive in France. Guile says it looks like he loused things up himself, and maybe she should have stayed with her special forces friends. Cammy tells him not a chance -he's so much cuter. She says now all they've got to do is find Zangief, as Guile says they need to figure out what he's doing on this train. They resume searching for him.

It turns out Zangief isn't trying to hide, as he's gone to get something to eat. Before he can take a bite out of his sandwich, Guile and Cammy find him. Guile tells him no snacking between meals, so he throws the sandwich at them.

Guile hits him with a sonic boom, and asks him to tell them what Bison is planning. But the train's power suddenly goes out, as it violently screeches to a halt.

The train stops, as some of Bison's men surround it. Guile and Cammy get up, only to find that Zangief is gone. He says they must have had this whole thing planned, and contacts Dee Jay for an update. Dee Jay tells him he'd better hear it from Honda, and Honda says Bison stalled their train halfway through the Chunnel. Bison's thugs are waiting at either end of the train, and are heavily armed. Guile realizes this train must be Bison's next target.

Rory and his team visit Bison, who tells them they will release him and hand over his billion pounds within the next twenty minutes, or they can kiss all those hostage passengers, and their precious Chunnel, farewell. Celia tells him this game's not over yet, but he laughs and says the fun has just begun. Back in the Chunnel, Guile and Cammy run to the front of the train, and find a couple of Bison's guys waiting.

They attack them from behind and take them down. There is then an explosion at the front of the train, so they have to drag the bodies of the guys they've just knocked out back. They then hear another explosion behind them, and realize that the back end of the train has been destroyed. Dee Jay then contacts them and says it's over -Bison's people know they are there now, and Bison intends to blow up the rest of the train unless he gets his money. Honda says the government is about to hand the money to Bison, and they want Guile to sit tight until this thing is over.

Guile tells them to not let them hand over the money, whilst he gets these people out somehow. Cammy asks how they're supposed to get them out, when they can't even get themselves out. Guile says they can take the service entrance, and throws a sonic boom at a wall. This reveals a service tunnel behind it, and he tells Cammy to get everyone to go through it. Meanwhile, Bison is released, and escorted outside by Burke's team.

A helicopter lands right in front of the ransom money, as Bison thanks them for their gracious hospitality. If they hadn't captured him in the first place, none of this would have been possible. Back in the Chunnel, the train passengers are all accounted for, and head down the service tunnel. Guile says they'll be safe now, even if Bison pushes the button to blow up the train. He contacts Dee Jay to confirm that the passengers are safe, and tells him to tell the special forces that they can nail Bison's hide to the wall.

News reaches Burke and the others, so Rory grabs Bison's cape. Burke tells him he's not going anywhere, but then he and his team come under fire by Bison's forces. Bison runs towards his helicopter.

Burke has his team fight back, as they quickly overwhelm Bison's forces. Bison is about to board his helicopter, but he falls out of it when a projectile lands nearby.

He sees Dee Jay and Honda in their helicopter, and uses his powers to destroy its rotor. They go down and crash land in a street.

Bison then knocks down Burke's team, and picks up the boxes of money. He heads back towards his helicopter.

However it turns out both Honda and Dee Jay have survived their crash without injury, as Honda charges towards Bison whilst using his 100 hand slap move. Bison throws the boxes at him...

...and they get broken, sending the money everywhere. Bison regrets the loss of his lovely billion pounds sterling, but easy come, easy go. Dee Jay contacts Guile and says good news, bad news. The billion pounds ransom is safe, and so are the passengers, but Bison got away again. Cammy says they saved hundreds of lives and a billion pounds sterling, but Guile says he doesn't feel like cheering.

The next morning, Cammy says goodbye to her old team. Celia wishes she wasn't going, as it seems like old times with her around. Rory says they still don't know who was helping them in the Chunnel, as it's all classified, but he has a a feeling her and her plumbing pal had themselves a bit of a workout. He thanks her for the assist. Burke takes Cammy aside and says that they need her -he needs her. She tells him he's never needed anyone, and neither has she. But there is someone he should consider, and tells him that Celia is an ace -maybe it's time he realized it.

He thanks her, and she says she has to go and make the world safe for plumbing fixtures. She walks away in tears, whilst he walks back to Rory and Celia and tells them it's tea time, and he's buying.

Cammy heads back to the Street Fighters, and Guile asks her if she's sure she made the right choice. Her special forces has first rate benefits, and a heck of a pension plan. Cammy tells him why bother, as working with him, there's no way she'll ever make it to retirement anyway. They all laugh and then head towards their plane.
