Crime Scene (2001)

In Crime Scene (2001), Charlie (Amber Smith) and her partner Terry (Chris Flanders) are homicide detectives assigned to investigate a series of bizarre murders in Los Angeles. Desperate for clues behind this series of steamy crimes, they enlist the assistance of a sex therapist (GiGi Erneta) famous for treating the most criminal of patients. When the good doctor takes them on a detour through the lusty path of curiously attractive taboo delights--and Amber finds herself becoming increasingly aroused by the therapist--these private dicks have to bounce back to business in time to solve the case.
