Murderous, sadistic London gang leader Vic Dakin, a mother-obsessed homosexual modeled on real-life gangster Ronnie Kray, is worried about potential stool pigeons that may bring down his criminal empire. The brutal Vic cuts the throat of one bloke who has been a little too loose-lipped, afraid that his gossiping may turn into a grand operatic performance for the coppers. Vic, who enjoys playing at rough trade with his sidekick Wolfe, plans a payroll robbery and directs the blackmailing of Members of Parliament with a taste for unorthodox sex. Scotland Yard Police Inspector Matthews, playing Javert to Vic's Jean Valjean, is moving in on him and the gang. Gang-member Frank is hospitalized for an ulcer, and Inspector Matthews might be able to make him sing. Will Frank spill the beans to the coppers before Vic can silence him?
