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.

When Sonny Drysdale promises to give Elly May a ring, Granny thinks he's going to propose and becomes a matchmaker. Cousin Pearl can't stand the idea that Elly May will get married before Jethrine, so she sets to matchmaking Jethrine with Jasper Depew.

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.

Granny and Cousin Pearl are at each other's throats over who's going to take care of cooking and the house, so Jed has to find ways to keep them apart. Jed tries to calm things down by taking a sightseeing tour of Beverly Hills.

Mrs. Drysdale leaves for a health farm saying Mr. Drysdale is "going to have a new wife" when she returns. Mr. Drysdale tells Cousin Pearl he'd like her to be his housekeeper. However, the Clampett's think he wants to marry Pearl, so Jed comes up with a plan to "save" the Drysdale's marriage.

Many animals and even the police respond to the unique sounds from Pearl's yodeling lessons.
