If the title Sins of Desire sounds like something advertised between infomercials on late-night cable television, congratulations: you've correctly identified its natural habitat. Directed by Jim Wynorski and released in 1993, this erotic thriller combines murder, sexual manipulation, undercover investigations, and enough questionable behavior to make an ordinary police station look like a model of workplace professionalism.
The story revolves around the Callister Institute, a sex therapy clinic operated by the thoroughly unscrupulous Dr. Scott Callister and his wife, Jessica. When Kay Egan suspects the clinic played a role in her sister's death, she goes undercover as a nurse to investigate. Meanwhile, private investigator Barry Mitchum is pursuing his own case involving a missing colleague. Naturally, their investigations lead them toward the same collection of deeply unpleasant people.
Because apparently nobody in this movie has considered opening a legitimate business.
Welcome to the World's Worst Therapy Clinic
The central premise provides plenty of opportunities for exploitation-movie absurdity. The clinic supposedly exists to help people with sexual problems, but its management is far more interested in abusing its position of authority. The patients are vulnerable, the doctors are predatory, and professional ethics appear to have been permanently removed from the building.
Wynorski knows exactly what kind of movie he's making. Sins of Desire isn't interested in presenting a serious medical drama or a sophisticated examination of criminal psychology. It's a pulpy mystery dressed up in the glossy, provocative style that defined so many early-nineties erotic thrillers.
Unfortunately, the mystery itself is considerably less compelling than the outrageous setting. The plotting occasionally becomes convoluted, the dialogue can be painfully clumsy, and the characters make decisions that seem designed primarily to get everybody into the next ridiculous situation.
A Cast That Keeps Things Interesting
Tanya Roberts plays Kay, while Nick Cassavetes appears as investigator Barry. Jan-Michael Vincent adds another familiar face as the suspicious Warren Robillard. However, John Henry Richardson and Delia Sheppard arguably provide the film's most entertaining performances as the clinic's sinister proprietors.
Richardson plays Scott with a combination of arrogance and sleaze that makes him an appropriately despicable villain. Sheppard's Jessica is equally manipulative, and their relationship provides some of the movie's more entertainingly unpleasant moments.
The performances aren't uniformly convincing, but perfection was never the selling point here. The film thrives on exaggerated personalities, suspicious behavior, and an atmosphere in which practically everybody seems to have something to hide.
Final Verdict
Sins of Desire is hardly a forgotten masterpiece of suspense. Its convoluted plotting and questionable dialogue prevent it from becoming a genuinely effective thriller. Nevertheless, it delivers the kind of trashy entertainment that made the direct-to-video erotic thriller such a recognizable nineties phenomenon.
