Robert Hossein and Marie-France Pisier star in this moderately suspenseful thriller. Peter is a laborer who dons fancy clothes and cruises the seedy dives of Dusseldorf for women. Whenever he is rejected by one of the females, he turns into a sadistic murderer. A shy young cabaret singer falls for Peter, but she too becomes a victim of his rage. Hossein's performance is devoid of any psychological insight as to why Peter has become an obsessive killer.
