Body of Influence (1993)

Synopsis
Softcore porn auteur Gregory Hippolyte directed this thriller featuring plenty of female nudity and starring Nick Cassavetes, son of famed indie director John Cassavetes. Beverly Hills shrink Dr. Jonathan Brooks (Cassavetes) seemingly has everything to lose: wealth, a successful practice, and a beautiful lawyer fiancée, Jennifer (Diana Barton). There's a serial killer on the loose in L.A., so Brooks is helping his cop friend Harry Reams (Richard Roundtree) compile a psychological profile of the murderer. Brooks is also treating an interesting new patient, Laura (Shannon Whirry), a shy hooker who transforms under hypnosis into a completely different woman, the seductive Lana. Brooks has a torrid affair with the irresistible Lana, but he's getting more than he bargained for. Lana steals the videotapes of her "sessions" with the good doctor and blackmails him with the damning evidence, destroying Brooks' life in the process. In the meantime, Harry closes in on a biker (Don Swayze) who might be the killer -- and the suspect has a connection to Lana. ~ Karl Williams, All Movie Guide
