Real-estate agent Jim Evers (Eddie Murphy) is given the task of shifting Gracey Manor, a delapidated old house in New Orleans, and decides to visit it with his family.

When they arrive, however, they come face-to-face with 999 grim, grinning ghosts who are not too keen on sharing their space with mortals.

With the help of supernatural psychic Madame Leota (Jennifer Tilly), the family must battle to break the mansion's curse before the clock strikes 13.
