As the movie begins, London arrives home from high school to find her mother trying to rape her brother, X-Ray Specks. London hides in her room and spray-paints her walls a strange shade of black as a metaphor for her impending loss of innocence. Later, X-Ray Specks tells London about the big fight coming on that night pitting his gang, the scooter-riding, suit-wearing, caucasian Mods against the greasy, motorbike-riding Japs. Meanwhile, M16 is clobbered by the Japanese gang and retreats into his own crazy boy-world where he collects newspaper clippings of the violent sort which he uses to try and impress his would-be-girlfriend, London, as evidence of his worldliness. As the sun sets, M16 and London meet for their first date in their favorite supermarket, while the two gangs prepare for their showdown in the ghetto.
