Having had the bad luck to witness a gangland murder, Fan (Michèle Cordoue) is promptly kidnapped by the killers' cohorts. She is then abducted by a rival gang, only to be re-kidnapped by her original captors. Held hostage to allow the murderer to escape, Fan's ordeal is compounded when the police begin closing in. Only the fact that the killer (Robert Hossein) falls in love with her saves the girl from further outrages -- but she's still not out of the woods as the picture draws to a close.
