There's nothing quite like family, even when that family is creepy and kooky.
And sometimes, that creepy, kooky, mysterious, and spooky family is incredibly wealthy and has a long-lost brother, presenting a fantastic opportunity for a look-alike to take the brother's place.
Of course, it wouldn't be any fun if the look-alike brother in question, Gordon, who goes by Fester, didn't start to like the family and feel like he might just belong after all.
Could he be the long-lost Fester after all? Will the Addams family accept him if he isn't?
