This low-grade thriller centers around Frank Waite (Art Hindle), a sports-car salesman who is suddenly mean-tempered when his wife Lee (Shannon Tweed) becomes turned off by sex, and Anouk Van Derlin, the sex therapist they decide to see (Carole Laure). As Anouk starts to bring out the suppressed sexual fantasies of the couple, their sex life is much better -- but both Lee and Frank are not completely at ease with their new, unrestrained relationship. In the meantime, a series of stabbings occurs in the city that may or may not be related to a transvestite neighbor of the Waites. But as the murders continue, some of the victims turn out to be friends or acquaintances of the couple -- and the guessing game to identify the real killer begins.
