Addams Family Values

Gomez and Morticia Addams have a baby, and name him Pubert. After a number of failed attempts by Pubert's siblings Wednesday and Pugsley to kill him, Gomez and Morticia gently rebuke them and hire a nanny, Debbie Jellinsky, to care for Pubert, unaware that Debbie is a serial killer who marries and then murders rich bachelors to collect their inheritances. After Debbie seduces Uncle Fester , Wednesday becomes suspicious of Debbie's intentions. To maintain her cover, Debbie tricks Gomez and Morticia into sending Wednesday and Pugsley to Camp Chippewa, a summer camp managed by the bubbly counselors Gary Granger and Becky Martin-Granger.

Wednesday and Pugsley are ostracized by the other campers, including popular and snobbish girl Amanda Buckman, for their macabre appearance and behavior. Joel Glicker, a nerdy bookworm and fellow outcast, becomes attracted to Wednesday. Debbie and Fester become engaged and get married shortly thereafter. On their honeymoon , Debbie attempts to kill Fester by throwing a boombox into his bathtub, but he survives.

Frustrated, Debbie forces Fester to cut ties with his family; when Gomez and Morticia try to visit Fester and Debbie, Debbie turns them away. Pubert transforms into a blue-eyed, rosy-cheeked and blond-haired baby. Grandmama attributes this to his disrupted family life, and Gomez becomes horribly depressed. Debbie tries to kill Fester by blowing up their mansion, but he survives again.

Debbie holds Fester at gunpoint, but Thing helps him escape. Meanwhile at Camp Chippewa, Wednesday is cast as Pocahontas in an upcoming play depicting the first Thanksgiving . When she refuses to participate, she, Pugsley, and Joel are all sent to the camp's "Harmony Hut" and forced to watch hours of saccharine, family-friendly movies and television shows. Afterwards, the three feign cheerfulness, and Wednesday agrees to participate in the play.

During the performance, Wednesday breaks from the script and leads the other outcasts to burn down the stage and capture Amanda, Gary, and Becky. Later, Wednesday and Joel share their first kiss before she and Pugsley escape, with Joel staying behind to lead their friends to ensure the camp's permanent destruction. Fester, Wednesday, and Pugsley return home, and Pubert is restored to his former self. Just then, Debbie arrives, holds them at gunpoint, and straps them into electric chairs .

Debbie recounts, using a slide show , how she murdered her parents and her first two husbands for incredibly frivolous and materialistic reasons. Meanwhile, Pubert escapes from his crib and reaches the family via a series of improbable events. As Debbie lowers the switch to electrocute the Addamses, Pubert connects two loose wires, rerouting the electrical current back to Debbie, which electrocutes her so severely that her body is reduced to dust. Some time later, the Addamses and their relatives gather to celebrate Pubert's first birthday, with Joel also attending.

Fester laments Debbie's loss, but soon becomes mutually smitten with Dementia, a new nanny that Cousin Itt and his wife Margaret Alford have hired for their child. Out in the family graveyard, Joel attempts to ask Wednesday out by asking about having a future with a husband, though she turns him down. She then tells him Debbie was not skilled at covering up her crimes, and that Wednesday would have scared her husband to death and made sure not to be caught. As he lays flowers on Debbie's grave, a hand emerges from the earth and grabs him, prompting Wednesday to smile as he screams.
