David Manning (John Collier), an old friend of Beaver's who now lives several miles away, invites Beaver (Jerry Mathers) to his birthday party one week in advance. Alas, by the time seven days have passed, Beaver has forgotten all about the party and has gone of on a photo-taking excursion with Larry (Rusty Stevens). Frantically, Ward (Hugh Beaumont), June (Barbara Billingsley), and Wally (Tony Dow) scour the town in search of the absent Beaver, who will ultimately be forced to make a difficult decision to avoid hurting David's feelings.
