Plot: The Addams step out of Charles Addams' cartoons. They live with all of the trappings of the macabre (including a detached hand for a servant) and are quite wealthy. Added to this mix is a crooked accountant and his loan shark and a plot to slip in the shark's son into the family as their long lost Uncle Fester. Can the false Fester find his way into the vault before he is discovered?
