At the Bank of England, some security guards are filling up a truck with bags of money. But as they drive off, Sodom appears in the middle of the road.

They attempt to go around him, but he uses one of his sais to cut through part of the truck, which causes it to crash into a lamppost. The guards get out, but Sodom has an ally: Birdie. The guards try to fight him, but he beats them all up.

With the guards taken care of, Birdie starts throwing some of the cash around and tells Sodom this was quite a haul -but it's only the beginning. The two start a crime spree across London, stealing more valuables and causing lots of property damage.

The police try to stop them, but they're no match for Sodom's strength. Birdie tells him that there's no one who can stop the pair of them. The next morning, at Scotland Yard, Burke, Rory and Celia are being sent to apprehend the two madmen involved. Their boss tells the press that they are the three who previously saved her majesty's government 1 billion pounds sterling in ransom, and captured the notorious crime lord M. Bison.

One of the press tells Burke that he may have caught Bison once, but he just as quickly lost him. What if he's the one behind this crime wave? Before Burke can answer, Rory speaks and says that first, they'll take care of the two thugs. As for Bison, if he's behind this and wants another round with them, he says they'll give it to him. This report is being watched by Birdie and Sodom.

They're not the only ones watching, as Bison is also there. He starts to put his plan into action, and calls Scotland Yard. He pretends to be a concerned citizen, and tells them about a crime that'll be committed tonight. Later on, Birdie and Sodom are sent to steal the Crown Jewels, which they manage to get to. Birdie puts a crown on and says he's the Queen, which Sodom finds very amusing.

However the crown then gets taken off of his head, as Rory says the Royal Family have already got enough trouble. Celia tells them that their crime spree is over, as Burke asks if they'd be inclined to come along quietly. Unsurprisingly, they don't, and charge towards the team. Celica takes out Birdie with a high kick...

...whilst Rory defeats Sodom by throwing him. He ties the two up and says that was a piece of cake, but what he'd really like is another crack at Bison. Just then, the cables he used to tie Birdie and Sodom up with suddenly come to life, and break apart.

One of them hits Burke, taking him out. Bison reveals himself, and this distracts Celia into letting Sodom grab her.

Bison asks Rory if he dares to face him alone, and Rory tells him he wouldn't have it any other way. He fires at him, but Bison uses his magnetic powers to stop the bullets before they hit him, and then send them back. Rory is hit in one of his arms, but Bison isn't done yet. He uses his powers to take apart one of Rory's cyber arms. Bison tells him next time he should think twice about angering one who commands magnetic force with the power of his own chi. But he tells Rory he never was very bright, was he?

Meanwhile, Guile and Cammy have arrived in London. Cammy is excited about being back in London and seeing her old chums, along with having the morning off to have a date with her boyfriend. Guile reminds her that they were called here by Escher on business, and this isn't a date, and he's definitely not her boyfriend! Cammy says not yet he isn't, but he will be -just give it time, he knows he cares for her. Guile says they've been through this before: he likes her, but he loves Lucinda.

Cammy repeats that name and says she dumped him once, so she'll dump him again. She lets herself fall off the wall and as Guile catches her, she tells him when Lucinda does dump him again, she'll be there for him. She tells him to get over Lucinda before kissing him. She tells him that Lucinda is his past, whilst she is his future.

As she walks off, she tells him that a person can't live in the past -the past is filled with pain. The two then meet up with Escher, who tells them that the A.N. has been called in on an urgent international manner. Guile and Cammy have been specially requested, and he says that Cammy's 3 former teammates from MI5 have been captured.

Cammy asks how, and Escher says he's been told they went down fighting, if that's any consolation. She says it's not, and just wants to be pointed towards Bison. He tells her it's not that simple, as Bison has already contacted Scotland Yard to negotiate their safe return. This time, he's demanding 2 billion pounds sterling, and also wants Guile and Cammy to be the ones who deliver it. Guile wonders why they are willing to pay so much for 3 field agents, no matter how good they are. Escher tells him it's because Burke recently discovered certain top secret data that could topple the British government. MI5 wants him retrieved before that information falls into Bison's hands. Guile and Cammy move out, and Guile tells her that whatever it takes, he promises they'll get them back.

In a warehouse, Burke and his team have been left in a cage. Guile and Cammy show up in a truck, and have the ransom money with them. Cammy wants her mates back, but Bison tells her first things first: he wants to see his money. Burke tells them not to give him the money and to just take Bison down, but Cammy says she has no choice.

Guile shows him a box of money and asks Bison if he's satisfied. Bison says he has his money, and he has them. He pulls a gun out on them and Birdie and Sodom move forward, but Guile and Cammy leap over them.

Guile kicks the gun out of Bison's hand, and it gets sent flying over to Celia. She uses it to destroy some of the cage's bars, letting her team escape.

Cammy kicks Bison over, whilst telling her old team it's good to see them again. Birdie tries to take on Burke, but he gets thrown straight into Sodom. Burke tells Cammy the feeling's mutual, and asks her if she's still on for dinner.

Cammy tells him as long as the main course is the roast rump of Bison, count her in. She and Guile go up to Bison, and Guile tells him this has been a long day coming. But he says it's not yet over, and he uses his power to protect himself with a shield they can't break through. Burke tells Rory to come and join the party, as he's missing all the fun. Burke tells him to give him half a mo, as he's a little busy here.

Bison calls him a muscle-bound oaf, but Rory finishes what he was doing and says whilst he may be a bit slow, it doesn't mean he's stupid. He charges forward, and Bison tells him if that's the case, how does he explain his fruitless action now? Last time they clashed, his magnetic powers tore his cybernetics apart. Rory reveals he's rigged his arm to generate the same magnetic charge as Bison's shield. Rory runs into it, causing it to break up.

Rory asks how it feels to be on the receiving end for a change, as he gives him a punch. Bison says not pleasant and kicks him back, but as he blasts him, the others surround him. Guile tells him he can't stop all of them, and Burke tells him that this time, he's going down. However Bison says he won't, not whilst he still has his secret weapon. He calls out to Cammy.

Cammy turns around and sees Bison's glowing red eyes, which triggers something in her. She falls to her knees whilst screaming.

Guile tells Bison to stop, so he does. Guile goes up to Cammy to help her, but she knocks him down with her cannon drill attack! Bison tells them that Cammy works for him... she has always worked for him. Cammy picks up a gun and tells Guile's group to stay back, if they touch Bison again she won't hesitate to use it. Guile tells her she doesn't want to do this, and Bison has messed with her mind. He tells her to remember who she really is, but she tells him that's just it -she has remembered, and the truth has set her free.

Bison and the others run to the truck, as Guile demands Bison change Cammy back to normal. Bison says what makes him think he hasn't done just that, but before he can get in the truck, Celia aims a gun at him. However he uses his magnetic powers to make her aim the gun upwards and fire it.

This causes the roof to cave-in, whilst Bison, Birdie, Sodom and Cammy all escape with the ransom money. Guile and the others get up out of the wreckage, and Rory asks if everyone's ok. Guile says it depends on his definition. Rory just doesn't get it, as no matter how powerful Bison is, he can't believe he could make Cammy betray them like that. Guile says he has done something to her, and warped her mind. They've got to get her back.

Guile reports back to Escher, who isn't happy at how not only did he lose Bison and the ransom, he managed to lose Cammy as well. Guile says they at least recovered Burke and his crew, that has to count for something. Escher tells him it does, but it's not enough. He says they'll have to be realistic here. He's also fond of Cammy, but if there's the slightest chance Bison is telling the truth for once, and if Cammy really always has been his sleeper agent, then he'd best be prepared to find some way of either curing her, or he'll have to terminate her with extreme prejudice.

At MI5, Honda and Chun-Li arrive to help. Burke is trying to bring up Cammy's old MI5 records, as he's hoping to find some clue as to what happened to her. However he finds out that somehow he has been frozen out, and Cammy's files can't be accessed, even by authorized personal. Chun-Li says maybe Honda can help, so Honda uses the computer. He says there is a lock on her files, and someone has changed the security codes.

He quickly manages to get it and bring up the file, but it then disappears from the screen. Burke says that somebody is trying to hide something from them, whilst Honda wonders who it is and why they've done it. As this is going on, Celia and Rory have gone to a pub, having heard it's a place that Birdie often lunches at.

They soon find Birdie when he starts to pick a fight with someone. Celia walks over and tells him she thinks he's going to just let that bloke go, and then tell them where they can find Bison. Later on they return to base, where Guile gets a plan together. With the info they got from Birdie, they now know where to find Bison. He's also gotten some satellite imaging shots of the location, showing a vehicle that Bison and Cammy are next to. Burke says it's a T-2 20 Skyhopper they're fueling, and it looks like Bison is getting ready to take off.

At the location, Sodom is loading up the Skyhopper with the ransom money. Bison tells him to load it quickly, but Sodom asks about Birdie -he's not back yet. Bison tells him Birdie knew their departure time, and if he's not here, then it's his loss. Guile and his group then arrive, and Guile tells Bison that actually, the loss is his. Bison tells them how he wishes he could stay, and then he, Cammy and Sodom run off into the Skyhopper.

Guile and the others move in, but Bison blasts off before they can do anything. Cammy tells Bison that was nicely done, and the two kiss, much to Guile's disapproval.

Guile throws a sonic boom at the Skyhopper, and Burke and Chun-Li also join in firing things at it, but they don't have any effect. However Rory fires a grappling hook at it, which successfully attaches.

But when it starts to move, Rory gets dragged up into the air. Honda tells him to hang on, whilst he uses his slaps to knock down a tower.

Rory grabs onto the top of it as it falls, which in turn stops the Skyhopper from fleeing. It starts to shake around and go wildly out of control, eventually resulting in the cable snapping. But it is sent flying straight into a building.

Guile's group move in to the crash site, but Bison and Cammy are nowhere to be found in the wreckage. Guile then spots them, and tells the rest of the group to stay here and deal with the fire, whilst he'll take care of Bison. Bison has been inured in the crash, so Cammy hijacks a car.

She and Bison speed off, but Guile sees them and starts running after them. Meanwhile Rory tears a water pipe out of the ground, as he and Honda use it to put out the fire. Chun-Li also uses her spinning bird kick to blow away some of the flames and smoke.

Bison and Cammy arrive at a dock, where there's a speedboat waiting. Guile sees them and thinks it's just like Bison to always have a backup plan. He cuts them off and tells Bison they can have it out, here and now. Bison tells him he would enjoy nothing more, but due to his injury, Guile has the momentary advantage. However Cammy steps in and tells Guile if he wants Bison, he'll have to come through her. Guile says he is her friend, the last thing he wants to do is fight her.

Cammy tells him to let them go, or she swears that only one of them will survive. Guile says that is the way it'll have to be, as he can't let Bison get away again. He's about to throw out a sonic boom, but then stops himself, saying he can't do it. Cammy calls him a spineless weakling, and brings the fight to him instead.

He gets kicked into some barrels, and gets up, only for Cammy to knock him down again. She goes back to Bison and tells Guile that she's warning him now -if he tries to follow them, she'll destroy him. They get into the boat, which she starts up. She tells Guile that the next time they meet, he will pay dearly for hurting the man she loves.

She and Bison head away in the speedboat, as Cammy swears that all the Street Fighters will pay. Guile can do nothing but watch them leave, as the rest of his group arrive. Burke asks what happened, and he explains that Bison and Cammy are probably halfway to Shadaloo by now.

Rory tries to look on the bright side by saying that at least Bison didn't get his blood money, so that's something. But Guile says Bison got a much bigger prize: Cammy. He says that the Street Fighters will not rest until they get her back.
