Wyatt Earp (Kurt Russell), a retired peace officer with a notable reputation, reunites with his brothers Virgil (Sam Elliott) and Morgan (Bill Paxton) in Tucson, Arizona, where they venture on towards Tombstone, a small mining town, to settle down. There they encounter Wyatt's long-time friend Doc Holliday (Val Kilmer), a Southern gambler and expert gunslinger, who seeks relief from his worsening tuberculosis. Josephine Marcus (Dana Delany) and Mr. Fabian (Billy Zane) are also newly arrived in Tombstone with a traveling theater troupe. Meanwhile, Wyatt's common-law wife, Mattie Blaylock (Dana Wheeler-Nicholson), is becoming dependent on a potent narcotic. Wyatt and his brothers begin to profit from a stake in a gambling emporium and saloon when they have their first encounter with a band of outlaws called the Cowboys, led by "Curly Bill" Brocious (Powers Boothe). The Cowboys are identifiable by the red sashes worn around their waist.
Wyatt, though no longer a lawman, is pressured to help rid the town of the Cowboys as tensions rise. Curly Bill begins shooting aimlessly after a visit to an opium house and is approached by Marshal Fred White (Harry Carey, Jr.) to relinquish his firearms. Curly Bill instead shoots the marshal dead and is forcibly taken into custody by Wyatt. The arrest infuriates Ike Clanton (Stephen Lang) and the other Cowboys. Curly Bill stands trial, but is found not guilty due to a lack of witnesses. Virgil, unable to tolerate lawlessness, becomes the new marshal and imposes a weapons ban within the city limits. This leads to the legendary Gunfight at the O.K. Corral, in which Billy Clanton (Thomas Haden Church) and other Cowboys are killed. Virgil and Morgan are wounded, and the allegiance of county sheriff Johnny Behan (Jon Tenney) with the Cowboys is made clear. As retribution for the Cowboy deaths, Wyatt's brothers are ambushed; Morgan is killed, while Virgil is left handicapped. A despondent Wyatt and his family leave Tombstone and board a train, with Clanton and Frank Stilwell close behind, preparing to ambush them. Wyatt sees that his family leaves safely, and then surprises the assassins; he kills Stilwell, but lets Clanton return to send a message. Wyatt announces that he is a U.S. marshal, and that he intends to kill any man that he sees wearing a red sash. Wyatt, Doc, a reformed Cowboy named Sherman McMasters (Michael Rooker), along with their allies Texas Jack Vermillion (Peter Sherayko) and Turkey Creek Jack Johnson (Buck Taylor), join forces to administer justice.
Wyatt and his posse are ambushed in a riverside forest by the Cowboys. Hopelessly surrounded, Wyatt seeks out Curly Bill and kills him. Curly Bill's second-in-command, Johnny Ringo (Michael Biehn), becomes the new head of the Cowboys. When Doc's health worsens, the group are accommodated by Henry Hooker (Charlton Heston) at his ranch. Ringo sends a messenger (dragging McMasters' corpse) to Hooker's property telling Wyatt that he wants a showdown to end the hostilities; Wyatt agrees. Wyatt sets off for the showdown, not knowing that Doc had already arrived at the scene. Doc confronts a surprised Ringo and kills him in a duel. Wyatt runs when he hears the gunshot only to encounter Doc. They then press on to complete their task of eliminating the Cowboys. Ike escapes when he gives up his sash, symbolically ending the Cowboys. Doc is sent to a sanatorium in Colorado where he later dies of his illness. At Doc's urging, Wyatt pursues Josephine to begin a new life. The film ends with a narration of an account of their long marriage, ending with Wyatt's death in Los Angeles in 1929.
