Andy and Helen are finally getting married and Andy is having his Bachelor party. The couple will honeymoon in Florida and Goober will be acting Sheriff. Opie will be on a camping trip and Aunt Bee is planning to leave Mayberry and live with her sister out-of-state. Sam asks Aunt Bee to move onto the farm with him and Mike, but she says her plans are made. It's the day of the wedding and Barney is best man. The happy couple leave for their honeymoon. Something the Reverend says leads Aunt Bee to change her mind about Sam's offer. But farm life might take some getting used to. Meanwhile, Howard reads a postcard from Andy to Goober and Emmett. Aunt Bee decides farm life isn't for her and Sam takes her large luggage out to the car. After speaking to Mike and looking at family pictures, Aunt Bee decides to overcome her fears and stay at the farm. We see Andy singing to Helen and then Barney is there as well.

The corn crop is coming in and Sam needs to hire someone to help him. Andy suggests using ex-prisoners from the county prison. Sam talks to Aunt Bee and she reluctantly agrees. Andy introduces Sam to Harry Davis and Charley Wilson. The men start picking corn and after a while, Sam gives them some money to run a few errands in his truck. They stop at Goober's gas station. Millie tells them that Goober's not there and they should just help themselves. They stop at Emmett's fix-it shop to pick something up for Sam. Emmett has to leave and he asks the men to watch his store. Meanwhile, Millie drops off a little more than $500 to Aunt Bee. Later, Sam and Aunt Bee find the money and car gone. Harry and Charley go to play cards with Big Louie. Andy and Sam show up and Harry and Charley say they were just trying to win the rest of the money for the pool. Big Louie gives Andy an additional $500 for the pool.

Andy and Sam think it would be a good idea to have a "Civic Youth Day". They would have some children take over as Sheriff, Head of City Council and County Clerk. But just for a few hours. Mike is chosen to be Sheriff, Arnold Bailey will be Head of City Council and Martin Barton will be County Clerk. The boys study for two weeks about their jobs. On the day, Sam, Andy and Howard quickly find out that the boys know quite a bit about the jobs. Later at a luncheon, the boys are to tell what they learned that morning. The boys don't have much to say. Sam apologizes because the men really didn't give the boys the added knowledge that they obviously wanted. The boys clearly embraced their roles with far more enthusiasm than anyone thought.

The town is excited about the Baseball Class "A" Excursion. While buying his ticket, Goober complains to Sam and Andy about the contents of the box lunch that will be included. Mike is excited to be going to the game. Sam becomes upset with Mike for losing a second jacket in less then 10 days. Mike has also lost several other items lately. Sam tells him that if he loses one more thing, he can't go to the game. Mike is playing baseball with some friends and he loses his watch. Mike tells Sam what happened and Mike knows he can't go to the game. Sam feels bad about enforcing his rule. It doesn't help that many townspeople are giving him a hard time about it. Andy gives Sam an idea of how he might be able to let Mike go to the game. Sam buys a similar watch and then sets it up so Mike can find it. While watching the game, Mike finds his original watch in his baseball glove. Mike realizes what his father did for him.

Aunt Bee and Sam prepare for a visit from Andy and Helen and their new baby, Andy Jr. After they arrive, Howard, Goober, and Emmett come by to see the baby. Goober, then Emmett and then Howard, each hint that they would like to be the Godfather. After they find out that Sam is chosen, the men are upset because they all feel they are closer to Andy. Andy notices that the three men have become very cold and distant to him. They're also distant to Sam. Andy suggests having four Godfathers and the men agree. But then the three fight over who will be the spokesman at church. It's the day of the christening and it still hasn't been decided who will be the spokesman. When the Reverend asks for the spokesman, all four men come up. Despite things being very unorthodox, the Reverend smooths things over. Later, Mike wonders why he doesn't have four Godfathers and Sam has to rectify the situation.
