Commissaire Valmont gets a call from one of her informers announcing that Madame de Farnelle, who is the landlady of a posh brothel [cum swingers' nightclub], is about to kidnap a girl at the time she's coming out of school. When she gets there, Valmont cannot prevent the kidnapping. On the evening, she goes to the kidnapper's nightclub [where an orgy is taking place with mostly masked participants apart from Cathy Stewart and Dominique Aveline]. Valmont arrests the owner for the kidnapping without any proof against her. Madame de Farnelle manages to to tell her son Antoine to take the kidnapped girl to the man who had asked for that special delivery. As her mother is kept at the police station, Antoine and two henchmen kidnap Sybil, Commissaire Valmont's own daughter, and offers to exchange her for Mme de Farnelle who manages to evade from the police when she is freed from prison after an agreement with them. Thanks to her informer, Valmont finds her hideout and raids it. Antoine who is now in love with Sybil, knocks his mother out when she tries to use Sybil as a shield.
