Notable lawman Wyatt Earp is determined to retire and put his violent past behind, as he silently moves to Tombstone, Arizona to settle down a peaceful life with his brothers Virgil (Sam Elliot) and Morgan. But a ruthless gang of deadly gunslingers called the Cowboys who widely plague the area and led by Earp's old Doc Holliday has burst on the scene, and Earp can't keep his gun belt off any longer.
