In the vibrant landscape of Hazzard County, Georgia, the Duke family thrives on their moonshine business, deftly managed by cousins Bo Duke, Luke, and Daisy. Their prized possession, a flashy 1969 Dodge Charger named "General Lee," serves not only as their primary vehicle but also as a beacon of their adventurous spirits. Yet, their uncomplicated lives are continuously disrupted by the nefarious actions of the corrupt local Commissioner, Jefferson Davis Hogg—better known as "Boss Hogg"—and his foolish deputy, Sheriff Rosco P. Coltrane.
Following a mishap involving Billy Prickett’s daughter that leaves the General Lee damaged, the situation intensifies when Billy Prickett, a famous stock-car driver, arrives in Hazzard County for an upcoming rally. At the same time, Sheriff Rosco exploits Uncle Jesse's misfortune by unjustly seizing their farmland for Boss Hogg's dubious schemes, forcing the Dukes to seek refuge with their neighbor, Pauline.
As the Dukes ponder their predicament, they come across a local construction site where they find a map highlighting their property among others, as well as a safe they suspect holds vital secrets that Boss Hogg would prefer to keep hidden. Although their initial attempts to break into the safe fail, they seek the assistance of Sheev, who manages to blast it open, revealing geologic core samples that spark the Dukes' curiosity, despite their uncertainty about what these findings truly imply.
Meanwhile, Cooter Davenport, the loyal mechanic to the Duke boys, dedicates his time to upgrading the General Lee into a formidable hot rod. He has high hopes for a reward if they triumph in the race ahead, unaware that the stakes are escalating rapidly.
As the Dukes make their way to Atlanta to consult geology experts, they encounter Katie-Lynn Johnson, a local from Hazzard County, revealing Boss Hogg's dastardly intentions to convert their community into a strip coal mine. Just as they plan to spread the word and garner support against this perilous proposal, they find themselves incarcerated.
Hogg pays the Duke brothers a visit in their cell, disclosing that the vote on his mining scheme coincides dangerously with the rally, using Billy Prickett as a cover-up. Meanwhile, Daisy devises a scheme to assist her brothers’ escape during transport. Together, the Dukes make a nail-biting dash, eluding the Atlanta Police and Georgia State Patrol as they race back home to alert their fellow citizens to the encroaching threat.
Upon their return, the brothers are met with a disconcerting scene: Boss Hogg and Rosco have taken Uncle Jesse and Pauline hostage. With little time to waste, they rush to the farmhouse to create a diversion that captures the attention of county law enforcement. Daisy and Cooter expertly formulate a plan to rescue Jesse and Pauline, showcasing their cleverness and bravery.
In another significant turn of events, college women along with Sheev attend a town rally to inform citizens about the imminent mining vote. Yet, due to Sheev’s reputation as a conspiracy theorist, they face skepticism from the community. Undaunted, Bo Duke heads to the rally to amplify their message while Luke and Jesse work in tandem to counteract the efforts of local and state police, engaging in a tense game of cat and mouse.
As tensions reach a breaking point, the brothers elevate their racing prowess, crossing the finish line first and leading the townsfolks on a chaotic chase throughout Hazzard County. Their ultimate goal? The courthouse, where they passionately advocate for the defeat of the proposed mining project. Though Boss Hogg attempts to imprison them again, an unexpected opportunity arises during the visit of the Governor of Georgia, with TV cameras rolling, as Daisy passionately appeals for their cause, ultimately persuading him to grant a pardon.
As the dust settles on their demanding journey, the Dukes and their friends come together for a festive cook-out at the farmhouse, celebrating their hard-earned victory and the bonds of family that have triumphed against all odds.
