JIMMY COOPER: "I don't wanna be like everybody else – that's why I'm a Mod, see? I mean, you gotta be somebody, ain't you? Or why not jump in the sea and drown?".
A bank holiday weekend provides the excuse for the rivalry between the two gangs to come to a head, as they both descend upon the sea side town of Brighton. A series of running battles ensues, based on the real-life "Second Battle of Hastings" riot of 1964. As the police close in on the rioters, Jimmy escapes down an alleyway with Steph (Leslie Ash), a girl on whom he has a crush, and they have sex. When the pair emerge, Jimmy is arrested and later fined £50.
JIMMY COOPER: "All right! I was there! Mods! Mods! Mods! There was a geezer, man, I tell you, I went, crack! Crack! We are the mods, we are the mods!"
Back in London, Jimmy becomes increasingly depressed and unstable as his life begins to fall apart. He is thrown out of his house by his mother, who finds his stash of blues (blue amphetamine pills). He then quits his job, blows his severance package on blues, and finds out that Steph has become the girlfriend of his mate Dave.
JIMMY COOPER: "it's just... I can't think straight, that's all. I mean, nothing seems right, apart from Brighton. Brighton was OK, going to court with the Ace and that. I was a mod there, you know? I mean, that's something, innit, eh?"
After a fight with Dave, Jimmy crashes his scooter, and, high on pills, takes a train to a now tranquil Brighton in an attempt to recapture the elation he felt during the holiday weekend. He revisits the scene of his encounter with Steph, and then discovers that his idol, the suave Mod "poster boy" Ace Face (played by Sting), is in reality a lowly bellboy at a Brighton hotel. He steals Ace's scooter and heads out to the cliffs at Beachy Head, where he rides towards the cliff edge. The film ends with the scooter smashing on the rocks below, but Jimmy's fate is not explicitly shown. However, since the film opens with a shot of Jimmy walking back from the cliff edge, he presumably jumped clear at the last second.
