Crimes of Passion (1984)

Synopsis
Joanna Crane (Kathleen Turner) is a cold, workaholic sportswear designer, divorced and dedicated only to her job. Once strapped into that role, Joanna looks for an "out" and finds it by donning a wig and hitting the pavement as a $50/trick hooker named China Blue. Explicit scenes show her at work on her night job, including a long S and M segment with a policeman. While making money as China Blue, Joanna runs into a menacing, fanatic preacher (Anthony Perkins) who is out to save her from this life of sin, but in the meantime, he is also busy watching nude girly shows. As China Blue and the sexually ambivalent Reverend heat up their relationship, he becomes difficult to read: is this psycho reverend a killer? While China Blue is plying her trade, Bobby Grady (John Laughlin) has finally realized after 12 years of marriage that his wife Amy (Annie Potts) is frigid and just as he has this remarkably delayed insight, he is assigned by Joanna's boss to find out if she is stealing designs or not. By tracking Joanna, Bobby sees her transformation as China Blue and as might be expected, sex is not far behind. ~ Eleanor Mannikka, All Movie Guide
