A P.I. is obsessed with a cute woman, who seduces and kills rich men around W. Europe.

Beauvoir, lonely, aging private detective, is put on the bloody track of beautiful Catherine Leiris who kills and robs her rich husband(s) on their wedding night. Although he never approaches her directly, he follows her and increasingly feels to be telepathically connected to her, because she reminds him of his daughter he never met. After he led a blind artist, Catherine's truly beloved spouse, into a bus accident, she makes a living by bank robbery with young Betty till Betty gets shot. Alone again, Catherine leads a sad, uneventful life as a waitress, when she meets her follower.—Knut Behrends <[email protected]>

The agency where the middle-aged private detective Beauvoir "The Eye" (Michel Serrault) works is hired by a couple to follow their son that is meeting a woman. Beauvoir is a bitter man that misses his daughter Marie that was taken by her mother years ago, leaving behind only a photo. Soon he finds that the youngster is having an affair with the gorgeous Catherine Leiris (Isabelle Adjani) and Beauvoir imagines that she might be Marie. Out of the blue, Beauvoir sees Catherine dumping the body of the man in a lake, but he does not report his finding. He follows Catherine who travels to another place and discovers that she is a serial-killer who misses her father and kills her lovers. Beauvoir protects Catherine and falls in love with her. When he finally meets her, he invites Catherine for a drink after hours. What will happen to them?—Claudio Carvalho, Rio de Janeiro, Brazil
