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.
The Darling family returns to Mayberry to look for a husband for Charlene's newborn daughter. Things get complicated when they choose Opie and refuse to take no for an answer.
Andy and Helen take a day off to go on a picnic, but are constantly interrupted by Barney, Goober and other people.
Barney returns to Mayberry to attend his high-school reunion.
Otis slips in the sheriff's office and a crooked lawyer convinces him to sue the county so it will be forced to upgrade the jail. Thinking Andy and Barney will be happy, Otis agrees.
