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 and Howard both decide to run for the office of town councilman.

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

Helen and her teenage students convince the principal the younger generation is no different from his own.

Colonel Harvey, a traveling salesman, arrives at Mayberry and captivates Aunt Bee, who buys Harvey's dubious elixir and invites him for dinner. When Andy and Barney find Aunt Bee clearly drunk, they analyze Harvey's elixir.
