context: Parisian illustrator Robert becomes obsessed with a young woman, Juliette. Night after night, Robert sneaks around the house to catch a glimpse of Juliette, until one day he finally gathers the courage to introduce himself. Juliette realizes that she is not happy with her fiancÃ©, Patrick, and leaves him to be with Robert. Robert in turn is not happy with Juliette's obtrusive advances.
  One night, Patrick attacks Robert in a deserted area; Robert defends himself and knocks Patrick unconscious, leaving him on the shores of a nearby river. The next day, Robert is interrogated by the police. Patrick is missing, and suddenly Robert is the prime suspect. Nobody knows that Patrick has allied with Robert's bitter ex-wife, VÃ©ronique, to take revenge on Robert; he is hiding from the police in order to make them think Robert killed him. Robert's professional and private life falls apart after becoming a police suspect. The situation escalates when Juliette commits suicide, and Patrick launches a vendetta against Robert. In a final confrontation between the men, VÃ©ronique is accidentally killed, and although Patrick is defeated, Robert is again left as a suspect in an apparent crime scene.
