Mrs. Drysdale is having a garden party and tells the Clampetts not to attend. However, they misunderstand and think she wants them to come. Jane and Drysdale try to stop them, but when they say how they still want to go, Jane arranges for them to have society clothes. When they arrive at the party, Mrs. Drysdale sends them back next door to handle the overflow crowd. But the clan gets bored, and decides to make it more exciting. When Granny sees an alligator in the pool, actually inflatable, she shoots it, and a few of Mrs. Drysdale's party guests rush over to see what happened, and decide to stay, especially when they see Elly and Jethro. Eventually the whole party ends up at the Clampetts, and they show these Beverly Hills folk how to have a real party.
