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. After finding oil on the land, the family is surprised when Mr. Brewster of the OK Oil Company offers to buy it. After much coaxing by Cousin Pearl, Jed sells the swamp and moves the family to a mansion in Beverly Hills. Upon their arrival, they are arrested because of a case of mistaken identity but are later returned to the mansion safely.

Jane Hathaway finds that making the Clampetts more sophisticated will be harder than expected, while Pearl Bodine tries to get the attention of Mr. Brewster.

Granny wants to go home because folks are so unfriendly and no one has come to call. Jed convinces her they should call on them, and they find that people welcome them and give them all manner of gifts when they show up on Halloween in their normal hillbilly clothes. Meanwhile, Jed works on getting Pearl to come visit while she's trying to get hitched to the oilman and find a young man for Jethrine.

Pearl continues to pursue Mr. Brewster, while a Jasper Depew courts Jethrine. Jed tries to enroll Jethro at an exclusive Beverly Hills elementary school. When the headmistress learns that the Clampetts are neighbors of Mr. Drysdale, who holds the mortgage on the school, she warms up to the idea. There is a bit of a shock when she comes by to pick up Jethro and realizes who will be her new fifth grader.

The Clampetts take their first plane flight back home for Christmas to visit cousin Pearl, who is busy cooking up a feast to win Mr. Brewster's unwilling heart. Mr. Brewster insults Pearl when he asks her to be his housekeeper, while she thought it was going to be a proposal.

Back home for Christmas, Elly May bonds with her old animal friends. Pearl plays the piano for the "new" movie in town (the silent version of Ben Hur) to impress Mr. Brewster. While Mr. Brewster tries to sneak out of the movie, Homer Winch declares his love for Pearl.

Mr. Brewster doesn't want to get married, but the whole county knows that Cousin Pearl had her heart set for him. Jed comes up with a plan for her to save face by having Mr. Brewster propose in public and then have her turn him down. Jed didn't count on Mr. Brewster's background in the theater and him making a huge production out of it. Mr. Brewster does such a convincing job that Pearl, after repeatedly saying no, then says yes.

The Clampetts pack up to return to Beverly Hills, so Jethrine tries to pack Jazzbo Depew. Elly says goodbye to her animals. Back in Beverly Hills, Miss Hathaway dresses the vamp to meet Jethro at the airport. Once home the feuding starts between Granny and Pearl over who's running Granny's kitchen.

The Clampett money keeps rolling in as more oil is discovered on their land. And Mr. Brewster is coming out to marry his fiancée, Edythe. Granny is planning to go back home to the hills, but Jed decides to put up the cabin.

The Brewsters come to Beverly Hills to build their new home on a vacant lot they purchased, and they request the Clampetts don't learn of this. But the Clampetts are planning to move back home to the Hills. When they tell Drysdale, he reveals the secret. Drysdale tells Brewster what he has done, but explains it was to save the Clampett oil account, and because of this, he has to visit the Clampetts.

After entering an oil deal with Jed and O.K. Oil, the Sheik befriends the Clampetts, giving Jed four of his dancing girls for wives and tries to get the beautiful Elly May as one of his wives. Jed tries to give the girls back, while Jethro tries to enjoy some of the Sheik's life, mainly the company of his beautiful dancing girls, after selling his cousin.

Granny and Elly head for the Ozarks to help deliver a friend's baby.

Jed gets a job as a garbage man & Mr Drysdale is shocked, so he gets him a position as director on the board of O.K. Oil Company. The Clampetts turn the company plane into a cheap airline & sell tickets to anywhere for the same low price.
