Helmut Berger is Alain, a real sicko, who may be so because his mother was a prostitute. He can only make love with a "decent" woman when she is drugged senseless, though he can manage one-time encounters with prostitutes and also gladly suffers the abuse of his boyfriends. He seems to have deliberately driven his first wife to suicide, and now he has married Nathalie (Virna Lisi). A police inspector (Charles Aznavour) has gotten wind of these doings, and attempts to intervene before a second tragedy can occur, but his superiors will not allow him to. This is a French language film, with no dubbing or subtitles.
