Nightmare Sisters is a 1988 campy sex filled horror film directed by David DeCoteau. The film stars the legendary scream queens Linnea Quigley, Michelle Bauer and Brinke Stevens. These three play an awkward trio of geeky, socially inept college girls who can't get a date. However one night they invite some fellow geeky college guys over to their place and decide to have a seance with them. The seance releases the spirit of a sex starved succubus who possesses the girls, turning them into mean, hungry and sexually obsessed monsters. Can the geeky guys overcome these vicious sex monsters? And do they even really want to, all things considered? This film is really just an excuse to show the women naked as much as they can. But really, is that surprising at all? No, not at all!moreless
