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.

Rafe Hollister, a farmer with a golden voice, is chosen to represent Mayberry at a musical, but Mayor Stoner believes he looks too seedy. It is then up to Andy to make Rafe presentable enough.

Opie meets Arnold Winkler, a spoiled kid who teaches him how to manipulate Andy into increasing his allowance by throwing tantrums.

A misunderstanding leads Andy and Aunt Bee to believe that they are both anxious to get married.

Barney interferes with Andy's attempts to romance Mayberry's County Nurse, Mary Simpson; when Andy suggests to Barney that he and Mary need some alone time, Barney immediately thinks that they are getting married.
