Eric is going on a business trip to a camping convention in Boston. Mr. Feeny is also going out of town, staying at a bed and breakfast. He asks Amy to take care of his house and water the plants, a task that she gives to Cory and Shawn.
In Boston, Eric runs into Feeny. The two converse and Mr. Feeny reveals that he conducts a long-distance relationship with a woman, who is also a teacher. Neither wants to give up their careers so they never get married, even though they meet perennially to ask each other.
Feeny has dinner with Elizabeth and when he returns, Eric sees that he looks troubled and goes to ask him about it. Feeny tells them that things went as they normally do; neither he nor she wish to give up their lives. Eric says that if they were really in love, they'd risk anything to be together. Feeny realizes that it's probably time to give it up. Having bonded, Feeny and Eric leave for a night on the town.
Meanwhile, Shawn is having trouble with his economics assignment, which is to create a fake business and write a report about it. When he goes along with Cory to water Feeny's plants, he gets the idea to turn the house into a Bed and Breakfast for the weekend.
Cory eventually agrees to go along, but he says that he will feel guilty if they aren't caught. "The universe will catch up with us," he insists. However, Shawn believes that they will actually pull it off. Everything goes according to plan. The guests leave quickly and quietly just before Feeny gets home. Shawn and Cory begin to leave when Mr. Feeny asks, "How much money did you actually make?" He informs them that the cab driver tipped him off. He takes the money that the boys made, promising to give it back when Shawn goes to college. "You've already proved to yourself that you have a future in business. That, and a college education, you'll do fine."
