Demon Slayer

Five delinquent teenagers are assigned the task of converting a long-abandoned mental hospital in South Central Los Angeles into a community center. Little do they know that the hospital much more than a crack house and refuge for the homeless: It is the site of centuries of mayhem and murder. Soon they are plagued by supernatural snakes, spiders, maggots, and images from the building's bloody past. In order to escape alive, the teenagers must conquer the demons that inhabit the hospital, in a battle where the division between the living and the dead is shattered. (official distributor synopsis)
