In a decaying British city of the near future, Billy is an ex-con adrenaline junkie dating the thrill-seeking Jo. Billy and Jo are leaders of a teen gang of "ram-raiders," thieves who jack a car, ram the vehicle through the front of a store, and steal whatever they can carry before the authorities arrive. A typical raid ends up in a high-speed pursuit by the police, which is all a part of the game for Billy, Jo, and their followers. However, a local drug lord, Tommy doesn't like the teen crooks infringing on his business. His opposition to their scheming leads to a deadly car race that plays out like a game of post-modern "chicken."
