At an old farmhouse, a family mysteriously dissapears at the hands of evil. Years later, hair metal band The Tritons comes to the farmhouse, whose barn now features a 24-track recording studio. Lead singer John Triton gets the band to perform their first night in the farmhouse after dinner, and weird little beasties suddenly appear, and strange things start to happen. Band members (and their tagalong girlfriends) begin to act strangely and vanish one by one. Soon, only John Triton remains, and he holds a secret. Finally, the evil shows itself and a battle between heaven and hell ensues....
