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.
Andy's knowledge of American history is put to the test by Opie and a new teacher.
A pack of hunting dogs overruns the Mayberry courthouse just as Andy is trying to impress a state official.
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.
Malcolm Merriweather, an English tourist, passes by Mayberry on a bicycle; after causing a traffic accident, he agrees to work off the damages as Andy's personal valet.
