Three generations of the same family deal with the consequences of unleashing the forces of hell. In 18th-century France, Paul L'Merchant (Bruce Ramsay) works as a toymaker until he's coerced into creating a box that serves as a portal between hell and Earth. The box summons demonic Angelique (Valentina Vargas) and Pinhead (Doug Bradley), who -- 200 years later -- hunt down John Merchant (Bruce Ramsay). Then, centuries later, Phillip Merchant (also Ramsay) prepares for a final confrontation.
