13 Ghosts

When an eccentric uncle wills a huge, ramshackle house to Cyrus and his impoverished family, they get the shock of a lifetime. Their new residence comes complete with a spooky housekeeper (Margaret Hamilton), plus a fortune in buried treasure and 12 horrifying ghosts--including a decapitated man, a wailing lady and a flaming skeleton--who are held captive in the eerie house and must find an unlucky 13th to free them!
