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.

Sam's cousin, Vince, is coming to visit. He used to be a jockey but now he trains horses. The next day Vince arrives with a horse named Gingersnap. Vince says that the horse has not lived up to its potential as a race horse. He's looking to sell the horse to finance a restaurant he wants to partner in and was hoping Sam could find a buyer. Aunt Bee thinks it's a shame to turn Gingersnap into a saddle horse. Emmett tells Sam that Mr. Bowers might be interested in the horse. But Aunt Bee manages to intentionally ruin the deal. She tells Sam her intuition tells her to put the horse in a race. Sam reluctantly agrees. Aunt Bee sets things up and gets the horse into a race at Morgan Downs. The day of the race, Aunt Bee gives the Jockey a pep talk. After the race starts, Gingersnap is in last position. The horse comes from behind to win. When Vince hears the good news, he decides to keep Gingersnap.
