The Addams family's lives begin to unravel when they face-off against a treacherous, greedy crafty reality-TV host while also preparing for their extended family to arrive for a major celebration.
Siblings Wednesday and Pugsley Addams will stop at nothing to get rid of Pubert, the new baby boy adored by parents Gomez and Morticia. Things go from bad to worse when the new "black widow" nanny, Debbie Jellinsky, launches her plan to add Fester to her collection of dead husbands.
When an evil doctor finds out Uncle Fester has been missing for 25 years, he introduces a fake Fester in an attempt to get the Addams family's money. Wednesday has some doubts about the new uncle Fester, but the fake uncle adapts very well to the strange family.
The Addams Family goes on a search for their relatives. Gomez and Morticia are horrified to discover that Grandpa and Grandma Addams have a disease that is slowly turning them "normal". The only chance they have of a cure is to find a family member hoping that they know a home remedy.
A satirical inversion of the ideal of the perfect American nuclear family, they are an eccentric wealthy family who delight in everything grotesque and macabre, and are never really aware that people find them bizarre or frightening. In fact, they themselves are often terrified by "normal" people. The Addams Family is the creation of American cartoonist Charles Addams.
