Millionaire Frederick Loren offers five people $10,000 to stay a night in a remote haunted house, giving each of them a loaded gun as a "party favor." Throughout the night, they're terrorized by skeletons, disembodied heads and other grisly apparitions. Will any of the guests survive to win the prize? Or will the house scare them to death? The legendary Vincent Price stars in one of director William Castle's most famous chillers.
