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.

Opie and his friend find an abandoned baby and run into trouble when they try to find it some new parents.

Andy unexpectedly has his hands full as The Darlings, a family of musicians from the mountains, arrive in Mayberry to meet a bus due the next day.

Andy uses common sense and Barney uses modern technology to solve several burglaries at a filling station.

Andy's knowledge of American history is put to the test by Opie and a new teacher.
