Naturally intrigued by Kirsty's tales of a puzzle
box that appears to be the key to the doctor's fixation, Channard reanimates Kirsty's stepmother (Julia) from the aforementioned haunted mattress, murders
off the inmates of his basement inferno to feed his new girlfriend (Julia, again), and gets Tiffany (Imogen Boorman), a mute girl who is adept at puzzles, to open the dreaded
antique, thus releasing the Cenobites and allowing entrance into the underworld.
