Confined to a mental hospital, young Kirsty Cotton (Ashley Laurence) insists her supposedly dead father is stuck in hell, controlled by sadomasochistic demons after being betrayed by his evil, occult-obsessed wife, Julia (Clare Higgins). Few believe Kirsty, except the thrill-seeking Dr. Channard (Kenneth Cranham), who is intrigued by S&M and the young woman's lurid stories. So when Kirsty and fellow patient Tiffany (Imogen Boorman) head to hell for a rescue, Channard and Julia are close behind.
