In the quaint town of Gilbert, Texas, Sheriff Ed Earl Dodd (Burt Reynolds) has nurtured a discreet but lasting romance with the enigmatic Miss Mona Stangley (Dolly Parton), who runs the notorious "Chicken Ranch," an establishment that has thrived illegally for almost a century. Their relationship is built on mutual respect and understanding, with Ed Earl willingly ignoring Miss Mona’s unorthodox profession in exchange for her generosity and commitment to the community. However, their seductive rendezvous are occasionally interrupted by Deputy Fred Wilkins (Dom DeLuise), yet their bond remains unwavering despite being clandestinely veiled.
The balance of their lives is disrupted when the town's mayor, Rufus P. Poindexter, and insurance salesman C.J. Vernon inform Ed Earl that consumer advocate Melvin P. Thorpe intends to expose the Chicken Ranch on his influential television show, The Watchdog Report. This revelation sends ripples of anxiety throughout Gilbert. Determined to confront the situation, Ed Earl visits Thorpe at his studio in downtown Houston, where he is taken aback by the television personality's bold accusations. During a raucous broadcast filmed in the town square, Thorpe publicly challenges Ed Earl, suggesting he has taken bribes to protect Miss Mona's interests. Furious, Ed Earl retaliates with threats of physical retribution should Thorpe ever set foot in Gilbert again.
The Chicken Ranch is woven into the fabric of Gilbert; it has become a time-honored tradition to celebrate the annual University of Texas Longhorns and Texas A&M Aggies football rivalry by hosting a party at the ranch, organized by the winning school's alumni association. However, Thorpe's sensational report and Ed Earl's volatile reaction thrust the Chicken Ranch into an unwanted spotlight. Consequently, Miss Mona reluctantly decides to halt regular operations but permits the football teams to continue their cherished tradition.
As the sun sets on the Chicken Ranch, tensions escalate when Thorpe's crew executes a daring nighttime infiltration, hoping to catch the unsuspecting Aggies and State Senator Charles Wingwood in the act. The following morning, Ed Earl returns home to find Miss Mona enraged by the blatant violation of her sanctuary and by Ed Earl's seeming failure to provide protection. Their heated argument spirals, with Mona denouncing him as childish, and Ed Earl firing back with a sharp retort > “It’s a hell of a lot better than being a prostitute.”
Still reeling from their clash, Ed Earl embarks on a secret mission to Austin, seeking to discuss the Chicken Ranch with the Governor of Texas. The pragmatic politician listens intently as Ed Earl passionately outlines the brothel's significance to the local economy and community. However, when recent polls indicate a slight majority of Texans disapprove of the establishment, the Governor instructs Ed Earl to close it down. As Ed Earl exits the capitol, he crosses paths with a triumphant Thorpe, leading to a chaotic scene where Ed Earl's fist connects with Thorpe’s face after yanking off his wig—all caught on live television.
Back at his office, Ed Earl delivers the somber news to Mona over the phone, informing her that the Governor has ordered the Chicken Ranch’s permanent closure. With regret over their earlier argument lingering, he requests that she accept the harsh reality. Initially heartbroken, Miss Mona’s spirits lift upon realizing Ed Earl’s unwavering attempts to salvage their beloved establishment.
As the chapter of the Chicken Ranch comes to a close, Miss Mona prepares to bid farewell, but not before Ed Earl surprises her with a marriage proposal. Understanding the implications of being linked to a man associated with such a controversial establishment, she hesitates and declines. Undaunted, Ed Earl expresses his desire to marry her despite any potential backlash or stigma associated with their past. To emphasize his commitment, he loads Miss Mona's luggage into his truck and invites her to join him for a symbolic ride toward a new beginning.
In the aftermath, Deputy Fred steps into the Sheriff’s role, while Ed Earl and Miss Mona tie the knot in a private ceremony. Years later, Ed Earl’s political career flourishes, culminating in a successful election as a member of the Texas state legislature.
