Keitel is a cop whose secret world of high living (financed by illicit side-dealing) is invaded by Lydon, who not only confesses to a spate of cop-killings, but seems to know more about Keitel than is comfortable. Two little balls of poison, they become locked together in sadistic games in which the captor needs his victim as much as the victim needs his confessor. The film (shot in English) is very much in line with the Continental habit of turning genres around - like Leone with the Western, this is a spaghetti thriller - and it uses the hard-nosed framework as a prop for its greater interest in the moral complexities of guilt, punishment and transference, rather than the traditional gestures of its US models. Keitel is his usual ineffable self, his features glassy with repressed anxiety and violence; the only miscalculation is the casting of Lydon (aka Johnny Rotten), who seems as threatening as a wet poodle.
