Jed Clampett, a hillbilly from Arkansas, accidentally discovers oil on his land while shooting at a jackrabbit, and suddenly his simple life is on the brink of a monumental change. When Ozark Mountain Oil shows serious interest in purchasing the property, Jed is offered a staggering sum of $1 billion, a figure that could rewrite his family’s future. Caught between comfort and opportunity, he consults those closest to him, and the idea of a new start begins to take shape.
During a family dinner, his sister, Aunt Pearl Aunt Pearl, argues that a change of scenery would do Jed’s daughter a world of good. Pearl and Jethro push for a move, and soon Jed, his daughter Elly May Clampett, Granny, and his nephew hit the road in Jethro’s rattling old truck, heading for Beverly Hills, California. Granny is reluctant but ultimately agrees to join the adventure as they embrace a city of glitz, glass, and a pace that couldn’t be more different from their Ozark home.
Upon arrival, Drysdale, the powerful head of the Commerce Bank of Beverly Hills, sends out his sharp-eyed secretary, Miss Jane Hathaway Miss Jane Hathaway, to meet the newcomers. The Clampetts’ arrival triggers initial misunderstandings—Jane even calls the Beverly Hills Police after mistaking them for burglars. After realizing Jed’s stubborn insistence on having Jane manage his affairs, Drysdale quietly relents and rehires her, hoping to keep a wary eye on the new neighbors while maintaining his own grip on their fortune.
As the Clampetts settle into their sprawling new estate next door to Drysdale, a cautionary dynamic unfolds: Drysdale’s son, Morgan Morgan Drysdale, is drawn to Elly May, who remains unpolished but endearingly earnest, while Jane finds herself navigating the chasm between etiquette and the Clampetts’ rough-hewn charm. Meanwhile, a scheming con artist, Laura Jackson Laura Jackson, teams with her partner Woodrow Tyler Woodrow Tyler to engineer a plan that could drain Jed’s newly earned fortune. Laura pretends to be a French etiquette teacher, Laurette Voleur, and sets out to win Jed’s hand, hoping to secure a marriage that would transfer his wealth into a Swiss account.
Before the wedding can occur, Granny overhears Laura and Woodrow scheming and even catches them sharing a kiss. Gashed by the betrayal, Granny resolves to expose the scam, but the pair quickly overpower her and ship her off to Los Viejos Nursing Home under the pretense that she’s their unstable relative. The wedding draws near, and the would-be con artists push ahead with their plan, but Jane soon uncovers the ruse. She discovers Laura’s true identity and, with Granny’s information, Racing against time, Jane and Barnaby Jones Barnaby Jones—the private investigator she enlists—work to foil the scheme and rescue Granny.
Jane disguises herself as a nurse and frees Granny, while a crucial call alerts the truth to Jed. Granny and Jane reach the wedding just in time, and they disrupt the scam, with Laura and Woodrow’s calculations collapsing when Jane uses a shotgun to disable the laptop they planned to use for the money transfer. The authorities move in, arresting Laura and Woodrow for their role in the plot, and Jed, guided by the setback, chooses to celebrate their misadventure rather than force a procession to the altar.
With the wedding canceled, the Clampetts decide to throw “one hellacious shindig” instead—a boisterous, country-inflected celebration that honors their family, their oil fortune, and the quirky, aspirational life they’re learning to navigate in Beverly Hills. The film closes on a note of uproarious reconciliation and the sense that, despite the cultural clash, the Clampetts’ bonds remain intact as they forge ahead into a new chapter together. > "one hellacious shindig"
