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.

Barney thinks it's time Andy got married, but Andy has a plan of his own.

Barney is left in charge of the sheriff's department when Andy has to leave Mayberry for the day to testify in a court case. When Andy returns, he finds out that Barney arrested almost half the town.

A nationally known confidence man becomes a hero to Aunt Bee, Opie and Barney when he is held in jail.

Andy tries to help Barney win the heart of his girlfriend, Thelma Lou. Everything goes smoothly until Barney misinterprets Andy's efforts and thinks he is trying to steal her away.
