Jimmy (Phil Daniels) is a member of a well-dressed, drugged-up teenaged gang called the Mods, forever duking it out with the cycle-punk Rockers. The rivalry between the two gangs comes to a head during three tempestuous days in the seaside town of Brighton. Here Jimmy makes love to lovely local Steph (Leslie Ash) and forges a strong friendship with unofficial Mod leader Ace Face (Sting). A series of disappointments and setbacks in his own London neighborhood convinces Jimmy to return to Brighton to pick up the pieces.
