Barney spends his life savings to buy a used car. Unbeknownst to him, the car is actually a lemon and has several issues and defects.

Malcolm Tucker, a wealthy businessman, has trouble getting his car to start and finds himself stranded in Mayberry on a Sunday.

Barney and Gomer are responsible for watching over two thieves who are temporarily jailed in Mayberry. Between the two of them, the criminals manage to escape three times.

Barney organizes a rescue party when Andy and Helen become trapped in a cave after it collapses. Unbeknownst to Barney, the two have already escaped, but decide to go back into the cave to save him from becoming a laughingstock.

Barney orders Gomer and Otis to keep watch on Andy when an ex-con Andy sent to prison many years before returns to Mayberry.

Andy uses common sense and Barney uses modern technology to solve several burglaries at a filling station.
