Extended version with unaired footage. Jed Clampett's swamp is loaded with oil. When a wildcatter discovers the huge pool, Jed sells his land to the O.K. Oil Company and at the urging of cousin Pearl, moves his family to a 35-room mansion in Beverly Hills, California.

The Clampetts finally arrive at their new home, but find there aren't any of the conveniences of their old home. Jethro makes a few new discoveries.

The Clampetts find that the comforts of the mansion do not always compare to the comforts of their former mountain shack. And Jethro and Elly get something from Miss Jane. Elly gets tips and gifts on how to be a Beverly Hills girl, and Jethro believes Jane likes him.

When Mr. Drysdale describes Mrs. Drysdale as being a hypochondriac, the Clampetts assume she must be a drunk. With his wife coming home, Drysdale and Jane try to prevent her from meeting the family before they can shape the hillbillies up.

When Drysdale suggest buying good stock, Jed quickly buys some cows, pigs and chickens. Meanwhile, Granny has plans to sober up Mrs. Drysdale, who the family believes is a lush. And Mr. Drysdale is trying to hide the new hillbilly neighbors from his wife.

The Clampetts are feeling homesick. They are mostly all alone in Beverly Hills and none of their neighbors are visiting them. So they decide to go visit their new neighbors.

The Clampetts are doing repairs for their home, and Drysdale and Jane have figured out a way to improve the Clampetts by lending them servants.

Jethro announces that Pearl has sent the family a letter. In this letter, Pearl says how she hopes her son is doing well in school. Jed realizes that Jethro should be in the fifth grade and tells him they have to find a school that day.

Elly May is set up with Sonny Drysdale.

Sonny and Elly are getting more serious. Sonny loves Elly's character and tells her how she makes him feel superior. But Jed worries about this courtship.

Granny is sure that Sonny and Elly will get married after she heard Sonny telling Elly he'll give her a ring at ten o'clock, not knowing that he meant a phone call.

Sonny has jilted Elly May and the Clampetts are prepared to feud with the Drysdales.

When Granny, Uncle Jed, Elly May and Jethro decide to return to the country for the holidays, they discover airline travel. Back home, Cousin Pearl and Jethrine make plans to visit the Clampetts in Beverly Hills.

The Clampetts arrive back at their old cabin to spend the Christmas holiday with Pearl. But since the cabin will be too crowded with the Clampetts and Brewster, Pearl suggests Brewster stays with her, in an attempt to get engaged.

The Clampetts are missing their Beverly Hills mansion, still living in their old cabin to help Pearl get Mr. Brewster. But Pearl is having no luck with hooking him - all her tactics are failing.

The Clampetts are heading back to Beverly Hills, taking Pearl and Jethrine with them. But Jethrine isn't too excited about it because she has to leave her boyfriend behind.

Pearl is trying to give Granny a break, figuring that Granny is so old and feeble that she cannot perform her household chores anymore. This upsets Granny greatly because she knows she can still get the job done.

Jed and Granny are discussing Mr. Drysdale, who they feel sorry for since his wife isn't in town much.

Pearl is setting up to give singing, yodeling, and piano lessons to the people of Beverly Hills. Duke is having problems with Pearl's yodeling because it hurts his ears, so he runs into the Drysdale yard, howling.

Pearl gets a letter from two old flames who used to fight over her hand, Lester Flatt and Earl Scruggs. After reading some of the letter, Jed figures that the engagement they talk about in the letter is for Pearl to choose which one she wants to marry.

Pearl gives up her music lessons because when she yodels, Elly's dogs storm her. Jed comes up with a plan to figure out how the dogs are coming in the house, and it is revealed that Granny is letting the dogs in.

Jed and Duke are feeling poorly, so Jed asks Granny to make some Spring Tonic for them. Granny tells Jed she can make the tonic, but it won't help because what they need is female company.

The Clampetts are visited by a stranger, H.H.H. Jones. But this man is a confidence man, looking to get rich by selling Jed different monuments in the Los Angeles area. He starts out by trying to sell the Hollywood Bowl.

The Clampetts want to go home because the hunting in Beverly Hills is poor. But Jed says they aren't going home just to shoot. Elly suggests they shoot skeet, which is what Drysdale shoots.
