Shortly after David and Diana's affair begins, Jerry is murdered, and the two prime suspects are Diana and Beth (Sheila Kelley), a friend and former girlfriend of both Jerry's and David's. The suspicion is mainly focused on Diana since she had attempted to kill her first husband, Ted (Rex Smith), in the first scene of this movie. She claims it was self-defense, but could it just be a homicidal pattern? Or could the possible killer be Beth, who may still have feelings for David, even though they split up years ago and are now "just friends"? Could she be jealous enough of his relationship with Diana to kill Jerry and frame his wife?
Despite the run-around, Jerry's killer is pretty obvious; in fact, you don't even have to watch the entire movie to know who it is--just read the tag line. But aside from that, "A Passion to Kill" is one of the few halfway decent B-grade erotic thrillers I've seen in awhile. The acting's pretty good, and I especially liked Sheila Kelley's character.
There is quite a bit of sex/nudity (at least on Chelsea Field's side) than violence or danger, and it's not as bloody as most psycho-killer movies go, though there are a couple stabbing scenes. But if you like low/medium-budget racy dramas, then "A Passion to Kill" is certainly worth watching at least once.
