Tanya Roberts stars in this erotic thriller in which she ends up teaming up with an insurance investigator (played by Nick Cassavetes) to go after a sex therapy clinic engaged in some foul play. The husband and wife (Callisters) running the clinic have caused the death of her sister and the investigator's female colleague. There are scenes of the two protagonists and of the two antagonists getting it on, as well as a scene between Tanya and Mrs. Callister. Good story, good action-packed climax. Worth checking out.
