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.
Andy, Barney, and Gomer take Opie and a couple of his friends on a camping trip. When Opie leaves early in the morning to pick berries, Barney and Gomer go looking for him but end up getting lost in the woods.
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.
Andy and Opie face the difficult problem of helping an old milk-wagon horse find contentment in retirement.
