Business is bad at the Shady Rest and Kate needs to make a $200 bank loan payment. Uncle Joe meets Henrietta Boswell and Gertrude Hawley, who are lost and looking for Madame Bovary's Hideaway Reducing Farm. He convinces them that the Shady Rest is the most exclusive reducing farm and charges them $200 for a week. The catch is that Uncle Joe provides them with a money back guarantee. Uncle Joe tries to hide from Kate why the women are staying at the hotel. With a rigged scale, Joe has to convince the two that the secret to weight loss is to eat whatever they want as long as it is combined with turnip greens. He also has them do what would normally be considered all his chores. Ultimately, the two women do whatever they can to find what they believe is Kate's miracle weight loss and youth secret.

Betty Jo has her first crush on a boy named Orville Miggs. But the object of her affections is more interested in tinkering with cars than he is in romance. As such, all Orville sees in Betty Jo is a mechanic's expert assistant. Kate doesn't want to see Betty Jo get hurt. Kate thinks he will see her in a different and more romantic light if she wears a dress and becomes a bit more feminine. But nothing they try makes Orville really notice Betty Jo, and ultimately give her her much wanted first kiss. If the family is able to accomplish their task, will Betty Jo ultimately think it was worth it?

Uncle Joe gets angry at Charlie and Floyd when he is left behind by the Cannonball. He decides to start his own transport business by using Orville Miggs' "Flivverball", an old car converted into a railway car. At first the Flivverball is a success. Kate must now deal with the feuding groups before the Cannonball goes out of business.

Charley begins to believe that everyone seems too busy to spend any time with him. Floyd has started to call on the widow Sarah Lawrence. Uncle Joe has a speech he has to prepare, so has no time to go fishing with him. Kate has far too much work to do around the hotel. Charley doesn't want to spend his time alone and miserable running the Cannonball. He decides to quit and move to the big city. Kate tries to manufacture ways of keeping Charley in the valley before his replacement Bill Tuttle comes and takes over his job. When Charley realizes how much he is loved and needed, he finds a way to talk Tuttle out of staying.

Uncle Joe isn't thrilled with the idea of turning the Cannonball's baggage car into a mobile library. He likes even less having to build the library shelves. But after meeting her, Uncle Joe grows extremely fond of pretty librarian Phyllis Marsh. Despite their age difference, among other things, Joe is not shy about romancing Phyllis. Phyllis has to find a way to let him down easy without hurting his feelings, because she is actually engaged. Phyllis introduces her fiance Hal Jackson to Kate. Kate comes up with a plan to show Uncle Joe how inappropriate he and Miss Marsh are as a couple.
