Addams Family Reunion is a movie from The Addams Family series. Discovering that his grandparents have developed "Waltzheimer's disease", Gomez organizes a family reunion, hoping that some branch of his enormous family tree will find a cure. Unfortunately, the company arranging the reunion misspells his surname and reunites him with the Adams family instead, including Dr. Philip Adams (Ed Begley, Jr.), who plans to poison his father and rearrange his will.
