Slaughterhouse Rock

This blood-soaked shocker seems to waver between standard horror and black comedy as it tells the tale of a young man who is so plagued by terrifying nightmares of a haunted prison that he is unable to function normally during the day. To understand the dreams, he goes to a dream interpreter who tells him the prison is the abandoned Alcatraz and that to stop the dreams, he must go there to face his fear. The young man brings a few skeptical friends with him. Once in the notorious, empty prison, the visage of a late rock star appears and explains the situation. Apparently the place is being haunted by the vile ghost of a US cavalry officer who enjoyed eating human flesh. The dead rocker then explains that the young man needs to destroy the demon before it kills again. Unfortunately, the creature has already begun possessing and killing the fellow's friends one-by-one. The soundtrack features music from Devo.~ Sandra Brennan, All Movie Guide
