Granny is cooking up some lye soap and Jed is worried the fumes will bother Mrs. Drysdale. Margaret is having a garden party that afternoon and goes to talk to Granny about the smell. The fumes are also destroying her hibiscus plant. Jed and Granny misunderstand Margaret and believe they are invited to the party. And Granny thinks that a hibiscus is in the body and wants to doctor Margaret. Drysdale sends Miss Jane to talk to the Clampetts. Jed thinks that a garden party is when you help someone make a garden. Miss Jane tries to talk the Clampetts out of going to the party and tells them it has nothing to do with actual gardening. They still want to go. Miss Jane shows Drysdale the Clampetts all dressed up. The Clampetts arrive at the party with some of Granny's "rheumatism medicine" and some country cooking. Margaret talks them into taking their stuff back and waiting by their 'cement pond' to handle the 'overflow' from her party. After Granny shoots a fake alligator in the pond, the crowd from Margaret's party come over to see what happened. They start drinking the spiked punch and the people are having a great time. With all her guests at the Clampetts, Margaret finally comes over and joins them.

Mr. Drysdale needs investors for his real estate development project, so he enlists the Widow Fenwick, and aims to cement the deal by hitching her to Jed Clampett, who is looking to find a mother for his daughter, Elly May.
