After her harrowing experiences in Hellraiser, Kirsty Cotton (Ashley J. Laurence) is a patient in a mental hospital under the care of psychiatrist Dr. Channard (Kenneth Cranham). Although outwardly calm, the demonic doctor unlocks the door to hell when he figures out the Lament Configuration. After he brings Kirsty's evil stepmother Julia (Claire Higgins) back from the dead, Kirsty, fellow patient Tiffany (Imogen Boorman), the evil doctor, and Kristy's stepmother all descend into the depths of hell. They battle the evil flesh-eating villains known as the Cenobites in this blood-and-guts gorefest. Kirsty hopes she can rescue her father from spending eternity in hell.
