Eccentric millionaire Fredrick Loren and his 4th wife, Annabelle, have invited 5 people to the house on Haunted Hill for a "haunted House" party. Whoever will stay in the house for one night will earn ten thousand dollars each. As the night progresses, all the guests are trapped inside the house with ghosts, murderers, and other terrors.

The reclusive Dr. Zorba has died and left his sprawling mansion to his nephew Cyrus and his family. They will need to search the house to find the doctor's fortune, but along with the property itself, they have also inherited the occultist's collection of thirteen ghosts.
