On orders from Governor Gosper, Wyatt Earp heads south when he learns that Old Man Clanton has sent his men into Mexico to steal the cattle of a wealthy rancher and rob the silver trains.

A headstrong teenager named Jimmy Craig arrives in Dodge City and wants to become one of Earp's deputies, demonstrating his impeccable skill with a gun, but his dream contrasts sharply with his irrational obsession to duel Ed Beatty.

Wyatt recalls the details of the day the Clanton gang rode into Tombstone to shoot it out with the Earps; he initially plans to avoid a street shoot-out by arresting the gang members separately.

Wyatt arrests the McLowery brothers, only to watch Sheriff Behan sheriff let them go right after, at the direction of Old Man Clanton.

Old Man Clanton's idea of a perfect son-in-law is Wyatt.

When a stagecoach is robbed, Wyatt uses the opportunity to turn the rival factions of the Clanton gang against each other to prevent a showdown between the gang and the Tombstone lawmen.
