Drysdale hears the animals and races over to the Clampetts. Drysdale tries to keep Margaret from hearing the animals. The Clampetts try to get some goat's milk to Margaret, because she's supposed to have that after the mash. Mrs. Drysdale is convinced she's imagining things, because she sees Granny hovering outside her window and sees a goat and a chicken in her bathroom. She decides to see the doctors in Boston.

Due to a misunderstanding of something Mr. Drysdale said, Jed believes Mrs. Drysdale (Harriet MacGibbon) is a drinking woman.

Miss Jane lets it slip that Milburn wants them to go to Palm Springs so Margaret doesn't meet them yet. As a favor to Drysdale, they will go. Thinking the Clampetts are gone, Milburn arrives at the mansion with Margaret. She sees Jethro with a shot gun and faints. Jed and Granny see her passed out in the car and think she's drunk.

Jed tells Mr. Drysdale that Cousin Pearl is taking care of his old cabin. Back at the cabin, Mr.Brewster tells Pearl that everyone arrived in Beverly Hills. He shows Pearl pictures of the mansion. Because she can't find a pump in the house, Granny thinks the only water they have is in the cement pond. Mr. Brewster offers to drive Pearl to the nearest phone so she can call Jed. During the drive, Pearl keeps trying to gain the attention of Mr. Brewster. Miss Jane comes by the mansion and finds Elly taking a bath in a wooden tub. Miss Jane tries to tell Granny that there are bath tubs upstairs. Granny says that they figured the upstairs belonged to someone else. Jethro tells Jed about his experience with a girl back in the hills. Jed is surprised when the story is more about cookies than anything else. Elly won't wear any of the clothes that Miss Jane brought. She thinks that a brassiere is a slingshot. Jed thinks that he's found a lot of water under his front lawn, not knowing that there is a sprinkler system there.

Mr. Drysdale shows the Clampetts the inside of their mansion. Drysdale says that Miss Jane Hathaway (Nancy Kulp), his executive secretary, will come by to help with hiring of the staff. Jethro asks Jed when he can taste Granny's moonshine and Jed says on his wedding day. Elly sees a telephone pole and thinks it can be used for fire wood. Elly and Jethro have a scuffle and she pins him down. Jed has a talk with Elly about acting and dressing more like a lady. Jed says he raised her like a boy and he's sorry he did. The Clampetts have to adjust to things such as refrigerators, ovens and the "cement pond" (swimming pool). Jethro also encounters a flamingo that he thinks is a chicken and tries describing it to the family. This causes Jed to suspect Jethro has been sneaking drinks of moonshine. Miss Jane arrives and thinks Elly is part of the "domestic" help. Jed and Jethro mistake a croquet ball for an egg. Miss Jane thinks Jed is the gardener, Granny the cook and Jethro the chauffeur. Things get confusing and Miss Jane tries to fire them. Drysdale comes by and explains to her that they are the Clampetts.

The pilot starts after the theme song when Jed struck oil in his Lake. A rural Ozark family relocates to Beverly Hills after oil is discovered on their property worth $25 million. Elly May (Donna Douglas) brings a Geologist (Ron Hagerthy) back to the cabin. He tells Jed that there's oil on his land and he leaves for Tulsa. Later, Cousin Pearl (Bea Benaderet) and her son Jethro (Max Baer Jr.) arrive. Jed tells Pearl that a Mr. Brewster (Frank Wilcox) of the OK Oil Company offered to buy his land. Pearl tries to explain to Jed that he is now a rich man. She tells him that he should move to Beverly Hills. Mr. Brewster comes by and also says Beverly Hills would be a nice place to live. He could have a bank out there find a home for Jed. The family and Jethro drive out to California. Jed's $25 million has been deposited in the Commerce Bank of Beverly Hills. Bank President Milburn Drysdale (Raymond Bailey) buys the mansion next to his for the Clampetts. The Clampetts arrive at their mansion. They mistake their new home for a prison and the groundskeepers for prisoners. The family is arrested because of a case of mistaken identity. After he realizes who they are, Drysdale has the family released from jail. Drysdale drives them back to the mansion, but still thinking it is a prison, the family runs away.
