Hedonist Frank Cotton (Sean Chapman) thinks he has reached the limits of earthly pleasure. But a mysterious puzzle box will take him further than he can possibly imagine, opening the doors to a dominion where pain and pleasure are indivisible and summoning the Cenobites, whose experiments in the higher reaches of experience will tear his soul apart. When he manages to escape, Frank returns to the world skinless and in need of help. Now his former lover Julia (Clare Higgins) must kill to make him whole again. But the Cenobites want Frank back, and there'll be hell to pay when they find him.
