Beaver (Jerry Mathers) swells up with pride when his teacher appoints him to the position of junior fire chief. Unfortunately, Beaver's ego swells as well, and before long he is using citations for the flimsiest of infractions, serving them upon neighbors, friends, and family members alike. It falls to Ward (Hugh Beaumont) to convince Beaver to avoid being carried away by his lofty position -- while at the same time not discouraging Beaver from taking his responsibilities seriously.
