Synopsis: The ghoulish cartoon family created by Charles Addams returns for a second big-screen outing darker and nastier than the first. When Morticia Addams gives birth to new baby boy Pubert, the other Addams children, Pugsley and Wednesday , devise any number of ways to kill off their new sibling. This leads Morticia and her husband, Gomez, to hire a nanny to oversee all three children. But the nanny has an agenda of her own, packing the Addams children off to a horrid parody of summer camp and setting out to seduce Uncle Fester all with the goal of getting her hands on the Addams family fortune.
