When occultist uncle Dr. Plato Zorba wills a huge ramshackle house to his nephew Cyrus and his impoverished family, they are shocked to find the house is haunted. Their new furnished residence comes complete with a creepy housekeeper, Elaine, plus a fortune in buried treasure and 12 horrifying ghosts. His family soon discovers that these spirits include a wailing lady, clutching hands, a floating head, a fiery skeleton, an Italian chef murdering his wife and her lover in the kitchen, a hanging lady, an executioner holding a severed head, a fully grown lion with its headless Lion taming, a floating head (presumably belonging to the tamer), as well as that of Plato Zorba himself, all held captive in the eerie house looking for an unlucky thirteenth ghost to free them. Dr. Zorba leaves a set of special goggles, the only way of seeing the ghosts.
