13 Ghosts

When Cyrus Zorba (Donald Woods) and his poverty-stricken family inherit an old mansion, they can't believe their good luck. However, not long after they move in they realize that the house is haunted by 12 ghosts and run by a housekeeper (Margaret Hamilton) who works in the dark arts. Though the ghosts are intent on killing a member of the family, the Zorbas insist on staying in the house because they have learned that a large fortune is hidden somewhere inside it.
