Slaughterhouse Rock

Alcatraz. For 39 years it held society's most depraved killers. Now it's home to something even worse...

A low-budget 1980s horror film that blends supernatural possession, demonic evil, and heavy metal aesthetics into a campy, visceral romp through Alcatraz's haunted past.

A man visits Alcatraz prison after having dreams about all the people who died there. When he gets there, his brother is possessed by an evil cannibal demon. The ghost of a female heavy metal singer who was killed there tries to help the man fight the monster.
