A millionaire offers ten thousand dollars to five people who agree to be locked in a large, spooky, rented house overnight with him and his Five people are invited by Frederick and Annabelle Loren to spend 12 hours in the house on Haunted Hill. All who manage to do so will receive $10,000. The house is presumably haunted – one of the guests, Mr. Pritchard, who seems to know a great deal about the history of the place and says there are seven in all – but greed drives most of the victims who immediately face various threats to their lives. A chandelier almost kills one; another is haunted by the ghostly apparition of an old crone; while yet another gets a bump on the head in a mysterious room. As the guests continue to be frightened and threatened, two have their own very specific reason for being there and not everyone will live through the night.
