As the enforcer of law in the town of Tombstone, Ariz., Wyatt Earp (Henry Fonda) must balance keeping unruly criminals in line with tracking down and bringing to justice the men who killed his brothers, Morgan (Ward Bond) and Virgil (Tim Holt). With help from Doc Holliday (Victor Mature), with whom he maintains a tepid friendship, Earp's pursuit ultimately involves the history-making confrontation at the OK Corral.
