Widowed sheriff Andy Taylor raises his son in Mayberry, North Carolina.

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.

Andy and Barney must figure out a way to prevent a farmer's goat who has eaten a load of dynamite from blowing up Mayberry.

Andy and Barney look forward to seeing their high-school sweethearts at the Mayberry Class of '45 reunion.
