Morticia and Gomez Addams (Anjelica Huston and Raul Julia) couldn't be more pleased with the newest additions to the family, mustachioed baby Pubert and perky nanny Debbie (Joan Cusack). Less pleased are siblings (and rivals) Wednesday (Christina Ricci) and Pugsley (Jimmy Workman), who want to rid themselves of the infant usurper while investigating the truth behind Debbie's exterior. Before the children can prove that Debbie is a homicidal maniac called the Black Widow--out to add Uncle Fester (Christopher Lloyd) to her collection of corpses--they are banished to summer camp. Can the Addams family survive the murderess and Kumbaya?
