The episode opens with George, Jerry and Elaine sitting at Monk’s Cafe. Elaine tells the two men that she is horribly allergic to her boyfriend’s cats. George gets a stock tip from a friend of a friend (Simon’s friend Wilkinson), and encourages Elaine and Jerry to invest with him. Based on George’s recommendation, Jerry invests $2500 into the company. Later, Jerry convinces his girlfriend, Vanessa, to go to a bed and breakfast in Vermont with him for the weekend. Jerry checks on the stock, and sees that it has dropped. Later, Kramer comes into the apartment to let Jerry know the stock has dropped again. Jerry tells George to talk to Wilkinson to get some advice on the stock. George tells him he can’t because Wilkinson is in the hospital.
Jerry eventually sells his stock for a loss, while George decides he’s going to go down with the ship. Jerry and Vanessa go to the bed and breakfast in Vermont as planned. Unfortunately, they are confined to the bed and breakfast all weekend due to rain. Out of curiosity, Jerry checks on the stock, even though he has sold his shares, only to learn that it has risen dramatically. Vanessa comments that the only reason Jerry has taken her to Vermont is because he lost so much money on the stock. The close quarters, combined with the short time Jerry and Vanessa have been together prove too much for the relationship, and they break up by the end of the weekend.
George, Jerry, and Elaine are back at Monk’s Cafe together, with George relishing in his earnings from the stock, treating the other two to anything they want to eat at the cafe. The waitress brings them the check, and George just hands her a wad of cash without even looking at the check, telling her to keep the change. He then asks to see it out of curiosity, and takes back some of the money he gave her. Elaine tells George and Jerry that she gave her boyfriend an ultimatum, either her or his cats; he chose the cats.
