Three plain looking sorority sisters (Linnea Quigley, Brinke Stevens, Michelle Bauer) decide to host a seance and invite their nerdy boyfriends to enjoy the fun. But when Omar (Dukey Flyswatter), a mystical shaman, suddenly appears in their crystal ball and tricks the girls into touching him, they're suddenly transformed into ravishing succubi, determined to suck more than just souls. Will the guys be able to stop the madness before it's too late?
