Buford "Bud" Davis moves to
Pasadena, Texas for a job at the
oil refinery his uncle, Bob Davis, works. Bud wants to earn enough money to buy land near his hometown of
Spur. While staying with Bob and his family, Bud embraces the local nightlife, including
Gilley's, a popular Pasadena bar and nightclub. Bud meets fellow Gilley's patron, Sissy. They marry soon after and buy a mobile home, settling into a routine of working during the day and socializing at Gilley's at night. Bud enjoys riding the
mechanical bull, but when Sissy wants to try, Bud forbids it. Wes Hightower, a recently paroled convict and
prison rodeo champion, is hired to operate Gilley's mechanical bull. One evening, a drunken Bud becomes enraged when Wes flirtatiously tips his hat at Sissy. A fist fight ensues, with Wes besting Bud. Wanting to impress Bud, Sissy secretly spends time at Gilley's where Wes teaches her how to ride the mechanical bull. When Sissy successfully rides the bull, Bud is angry that she defied him. During Bud's ride, Wes intentionally swings the bull around hard, breaking Bud's arm. At home, Bud and Sissy argue. She claims that Bud is jealous because she rides the bull better, causing Bud to slap Sissy and throw her out of their mobile home. Some nights later, Bud sees Sissy at Gilley's and smiles at her. Still angry, Sissy ignores him. Bud angrily retaliates by dancing with Pam, a rich oilman's daughter. Bud makes sure that Sissy sees them leaving together. Sissy moves in with Wes, who lives in a run-down trailer behind Gilley's. Bud, unable to work while wearing an arm cast, wants to compete in Gilley's upcoming mechanical bull riding rodeo contest for the $5,000 prize. While Bud is training with his uncle, a former rodeo champion, Sissy stops by the mobile home to collect her belongings. While there, she cleans and leaves Bud a note saying she hopes they can reconcile. Pam finds Sissy's note and throws it away. Bud arrives and thinks Pam did the cleaning. Sissy catches Wes in bed with Marshalene, who works at Gilley's. When Sissy reacts angrily, Wes slaps her. Bob urges Bud to reconcile with Sissy, citing how he nearly ruined his own marriage. Soon after, Bob is killed in a refinery explosion, devastating Bud. At the funeral, Sissy tells Bud that Wes was fired from Gilley's, and they are leaving for Mexico after Wes wins the contest. Bud plans to skip the contest but Aunt Corene insists that Bob would want him to compete. Bud wins the contest but is disappointed that Sissy is not there to see his victory. Pam realizes that Bud still loves Sissy and urges him to reconcile with her. As Sissy is waiting in her car behind the bar, Wes sneaks into Gilley's main office armed with a pistol to steal cash. Bud finds Sissy in the parking lot and says that he loves her and apologizes for hitting her. When Bud sees Sissy's bruised face, he goes after Wes. A fight ensues outside the bar. Wes drops his gun, and the stolen money falls from his jacket. Wes is apprehended while Sissy swears she knew nothing about him robbing the bar. She and Bud go home together. ==Cast==
