Wyatt Earp moved to Tombstone, Arizona to retire from a lifetime of law enforcement, but soon found himself entangled in a battle with a gang of local outlaws known as the Cowboys. Wyatt, along with his brothers Morgan and Virgil, and their friend the dentist, gambler and gunman John Henry “Doc” Holliday, clashed with the Cowboys in the gunfight that became known as the shoot-out at the O.K. Corral.
