Mercy on AllMovie

Damian Harris directs this sleazy erotic thriller about lipstick lesbians, naked corpses, and S&M covens, starring Julian Sands. Catherine Palmer (Ellen Barkin) is a hard-driving homicide cop who drinks like a fish and curses like a sailor, investigating a series of murders which leave the (inevitably female) victims bound, naked, and eyelid-less. Tall drink of water Vickie Kittrie (Peta Wilson), who was last seen with the latest victim, eventually admits involvement with a tribalistic S&M society. Palmer dutifully accompanies Kittrie on one such outing, featuring pouting models in designer corsets and lots of heavy breathing. When the serious girl-on-girl action kicks off though, Palmer makes a beeline for the door, only to be seduced by Kittrie against her kitchen sink (a la Fatal Attraction). Meanwhile, lead suspect psychologist Dr. Boussard (Sands) continues to snivel and cross-dress as the bodies start piling up.
