Andy Taylor is the widower sheriff of the small, sleepy North Carolina town of Mayberry. Andy and son Opie live with Aunt Bee, who takes care of the family. Andy's deputy is his bumbling but neurotically hilarious cousin, Barney Fife. Among Andy's Mayberry friends is the town's resident barber, Floyd.

Aunt Bee does well with her flying lessons, until her instructor tells her that she is ready to solo.

Andy, Barney and Opie substitute Aunt Bee's terrible homemade pickles with store-bought ones to avoid eating hers. Their plan backfires when Aunt Bee decides to enter them in the county fair.

Andy learns that Helen was once arrested for gun possession, gambling and keeping company with a hoodlum.

A trial run as sheriff of Mayberry convinces Barney that he is not ready for a similar job in a nearby town.
