"Minerva" eases the girls concerns and announces that this is her last column.

Because Uncle Joe is supposed to paint the Hotel, he gets the idea that he can go into business as a general contractor. He finds out that the wealthy Douglases are looking for a contractor to help fix up the "Green Acres" farmhouse. He does get Mrs. Douglas to hire him. Although Joe knows nothing about construction work, he tries to juggle the hotel and the Douglas jobs. Joe also finds that he may be scheming rich, but cash poor.

Uncle Joe answers the ad of Dr. Mathew Bailey. Dr. Bailey is looking for office space in return for free medical service. Kate doesn't think it's a good idea, especially with everyone in Hooterville going to see Doc Stuart. But once the girls get a look at the young and handsome Dr. Bailey, there is no way they're going to let Kate let him get away. So they open up an office for Dr. Bailey adjacent to the hotel lobby. But Kate is right, there is no business for Dr. Bailey as many locals see him as too young and inexperienced. The girls and Uncle Joe go on a marketing spree to round up patients, to no avail. Doc Stuart unwittingly gives Kate an idea to boost Doc Bailey's clientèle. Kate's plan takes an unexpected turn. Elsie Baker appears as a townswoman.

What Kate and girls don't realize is that Herbie is King Ring a Ding. When Herbie hears that no tickets have been sold mainly because he's the "headliner", he comes up with a plan.

He thinks he's found that person in Herman Crawley, the strong as an ox but not too bright plumber Kate hires. Joe sets up a makeshift boxing ring at the hotel to train Herman, which doesn't sit too well with Kate. When Joe meets Kid Dynamite and his brazen manager mother Mrs. Hogan, Joe thinks there's no way Herman can lose. So Joe makes a $500 versus the hotel side wager with Mrs. Hogan on the outcome. What Uncle Joe doesn't realize is that Herman has a particular weakness. Uncle Joe has to protect Herman's weakness and find out and exploit the Kid's weakness.

One of Kate Bradley's old swains named Ralph Denton sends a telegram stating that he is coming by the hotel for a few days. Uncle Joe thinks Kate is acting just a little too nonchalantly, which means she still has feelings for him. Ralph shows up with his overbearing and busybody spinster sister, Mabel. The girls and Uncle Joe do whatever they can to preoccupy Mabel so that Ralph and Kate can have some romantic alone time together. But Joe's spending so much time with Mabel leads to an unintended marriage announcement.

Kate tries to persuade Joe to give the post office back to Sam and for Sam to take it back.

Billie Jo wants to move out of the hotel and into her own apartment in Pixley. Kate repeatedly says no. Kate finally gives in, but she has to approve of the place and the landlord.

Joe secretly pays off all of Kate's bills. Even though she doesn't know who to thank, Kate is surprised and happy. Uncle Joe learns that the money was probably stolen from the Crabwell Corners Bank. Joe takes what moneys left and returns it to the can. He then finds out that the stolen money was found somewhere else. But before he can get the money back, he hears that someone else's dog dug it up

Uncle Joe is excited by a letter from Jeff and Nancy Anderson. They honeymooned at the hotel and are planning on returning for their tenth wedding anniversary. This gives Joe the idea to market the hotel as a second honeymoon haven for past honeymooning guests. The girls suggest they hold a gala reunion. They send out invitations and all the invitees have to do is fill in the dates they will be staying. The plan doesn't work as every single couple turns them down. The Andersons arrive and are looking forward to a quiet second honeymoon. But Joe's constant attention and picture taking is starting to bother them.

Not knowing about the possible deal, the girls imply that they'd love to live in New York City. When Mr. Deming offers Kate much more than the hotel is really worth, Kate reluctantly accepts his offer. Kate tells the girls that the hotel is sold and they are upset. Despite what they said, they don't want to move from the Shady Rest and Hooterville. The problem is that Kate verbally promised Mr. Deming that she wouldn't back out of the deal.

The cheap refrigerator that Uncle Joe bought isn't working, so Kate sends him into Pixley to get some ice for the icebox. Floyd and Charley are having a fight over who is the boss of the Cannonball and then they have a fight over a missing apple. Because of this, Joe can't get to Pixley and Kate's food will spoil.

Kate is cleaning out the storage closet. She wants the family members to go through their belongings to see what can be thrown away. Uncle Joe thinks they should start an antiques business with the junk. Everyone is around to help except Betty Jo, who should have been on the afternoon Cannonball run from school. Floyd and Charlie tell Kate that they saw Betty Jo that morning. She was all made up and had a suitcase. It looked like she was about to run away to elope. Kate and the girls look for clues in Betty Jo's room. They find a notebook that leads them to believe that Betty Jo might be thinking of eloping with the new boy in town, Peter Latimer. Betty Jo is actually just coaching baseball to Peter were no one can see them. Kate visits Mrs. Latimer to tell her that their children have eloped. When Betty Jo and Peter come home, everyone finds out that they were worrying over nothing.

Kate's widowed friend Vera Wilson has been dating Ronnie Beckman, a bookkeeper who moved to the valley five years ago. Kate wants to know when they're getting married, but Vera says the relationship is going very slowly and she doesn't want to seem pushy. Kate runs into Ronnie on the Cannonball. He tells her that he's not sure about marriage as he has always been alone. Floyd thinks that Kate and Ronnie are sweet on each other. Ronnie wants to stay at the hotel to see how happy real family life can be. When they arrive, the sisters are fighting. Kate tells them they have to look like a happy family in front of Ronnie. Uncle Joe thinks Ronnie wants to marry Kate for her money, so he talks down family life. Kate tells Ronnie that they were putting up a front and that they often fight. Ronnie is glad, as it wouldn't be natural to be that nice all the time.

It seems that every night everyone has something to do except for Kate. Uncle Joe tells Kate that she needs to get out herself. The girls decide to try and find Kate an eligible bachelor. They first tell Kate that they're grown up now, she doesn't need to take care of them and she should go on a date. That direct approach doesn't work. Their next attempt fails as well. They then ask Mrs. Douglas for her advice. Mrs. Douglas suggests holding a lonely hearts club gathering at the hotel. Three desperate men show up at the hotel hoping to meet some women. Once she knows what is going on, Kate finds a way to get each of the men to leave

Uncle Joe is excited about a new capital works project for the valley. The plan is to dam up Bleeker Creek which will create a new lake in the area. Kate points out to Uncle Joe that the location of the new lake does not mean that the hotel will be lake front property, but rather be under water in the middle of the lake. When she sees how this project will devastate her and the Cannonball, she knows Homer Bedloe is behind it. Kate needs to collect two hundred signatures for a restraining order petition. When Kate comes up two signatures short, Mr. Fletcher the Commissioner of Conservation, says nothing will stop them from putting in the lake. Uncle Joe's dog winds up saving the Shady Rest.
