Three socially awkward sorority girls invite three fraternity pledges over for a night of fun, but when the group holds a séance, the girls find themselves possessed by a shaman who transforms them into lustful, uninhibited succubi.
Nightmare Sisters is a 1988 direct-to-video, low-budget, horror comedy. It is notable as one of only two films in which 1980s scream queens Linnea Quigley, Brinke Stevens, and Michelle Bauer appear together, excluding later reunion films such as 1313:Cougar Cult.
