Kirsty Cotton has been admitted to a psychiatric hospital, still haunted by visions of the horror that destroyed her family. As Doctor Channard (Kenneth Cranham), and his assistant, Kyle MacRae (William Hope) interview her, she tells her account of what happened to her family. She pleads with them to destroy the bloody mattress her murderous stepmother, Julia Cotton (Clare Higgins) died on. MacRae is the only one who seems to believe her. However, it is revealed that the obsessive Dr. Channard has been searching for the Lament Configuration, the doorway to the world of the Cenobites, for years.
