Wally, the Beaver's big brother gets all the attention he can handle from his wife and his school sweetheart at his high school reunion. Several guest stars from the original show return, including Cheryl Holdridge as Wally's former sweetheart. The episode begins when Eddie Haskell and the Reunion Planning Committee gather to arrange the event. Haskell tries to impress his old nemesis Danny Pellino by renting a flashy car and disguising his wife as Genevieve, his French bride. Wally and Beaver reprise that "Mohawk" scene they did years ago - with a new twist.
