Granny's been letting Elly's dogs go after Pearl every time she yodels. Jed catches Granny and makes her stop. So now Granny calls the police. Sergeant Dean and Officer Kelly arrive at the mansion again. Dean really likes Pearl's yodeling and joins her in song. Kelly is still fond of Elly and goes to see her by the pond. Elly is putting firewood under Granny's still. Kelly doesn't know what a still is, but he tells Elly she shouldn't have an open fire in the yard. When Dean takes Pearl outside to the squad car, Granny thinks she got Pearl in trouble and becomes sad and contrite. Kelly describes what he saw to Dean and Dean says it's for making moonshine. Granny continues to apologize to Pearl. Dean and Kelly figure Granny doesn't know it's illegal to run a still. Granny hears the men talking. She misunderstands and thinks Pearl turned her in. To protect Granny, Jed, Elly and Jethro each say the still is theirs to Dean and Kelly. The men won't do anything if Granny promises to stop making moonshine.

Harry Jones arrives at the mansion and pretends to be an old family friend. Meanwhile, Miss Jane tells Drysdale about a conman named Harry Jones who is in the area. Harry suggests to Jed that he buy the Hollywood Bowl from him because Pearl could do her yodeling there and sell tickets. Harry and the family drive there to take a look. They get out onto the stage of the Bowl and are very impressed. Harry tells Jed that if he likes hunting, there's no better place than Griffith Park. Pearl is distracted by fantasizing the Bowl is full of people chanting her name. While driving to the Park, Harry tells Elly that if Jed buys the park, he'll throw in all the animals in Griffith Park Zoo. Drysdale and Miss Jane go to the Clampett mansion and find no one there. At first Drysdale doesn't think that Harry could've singled out the Clampetts for his con game. But then they head to the Hollywood Bowl. The Clampetts are impressed by all the animals at the zoo, but Elly thinks they should be set free. On the drive home, the other drivers are honking and yelling at the Clampetts. Harry offers to sell Jed the freeway so he could make the people drive the way he wants. The others drop off Jed and Harry at the mansion. Granny, Jethro and Elly go back to the freeway with their guns to teach the drivers some manners. Miss Jane and Drysdale tell Jed that Harry is a crook. Jed said he found out that Harry is no mountain man because he couldn't hold his liquor.
