In British television writer-director Kevin Allen's feature film debut, the industrial town of Swansea, Wales, is viewed through the post-punk lens of disaffected youth. Lower-class, crude, drug-addled brothers Julian and Jeremy (played by real-life brothers Llyr Evans and Rhys Ifans), steal cars, smoke dope, and terrorize the town on their joy rides. They are thought to be twins but really aren't. Their father Fatty (Hugh Ceredig) is injured while working for corrupt contractor Bryn Cartwright (William Thomas). Jeremy and Julian want to be compensated with money for their dad's injuries, but Cartwright refuses. Posing as a respectable businessman, he is actually a drug trafficker in cahoots with two corrupt policemen, Greyo (Dorien Thomas) and Terry (Dougray Scott). Greyo is smitten with the brothers' sister, who is a prostitute. The "twins" go after Cartwright and his associates with a vengeance, inflicting sick brutalities on their pets and their families.
