This gunfight would define the rest of his life. Earp's modern-day reputation is that of “ The toughest and deadliest gunman of the old West"
The movie starts with young Wyatt preparing to run away from home and join the Union army like his brothers Virgil and James. His father Gene Hackman in a cameo role, stops him. While Wyatt wants the same adventure he feels his brothers are experiencing, his father knows the horrors and truth about war . Later, James and Virgil return home both exhausted and beat up from serving in the army. Their father has put on his traveling shoes and announces that the family will be moving West where opportunity knocks. Wyatt finally ends up as a lawman and along with his brothers, clean up Dodge City.
The escalating tension climaxes with the famous Gunfight at the O.K. Corral, in which the Earp brothers helped by Holliday kill them three Cowboys. The Earps are subsequently targeted with retribution attacks, with Morgan killed and Virgil maimed. Wyatt sets off to kill all remaining Cowboys, before continuing his life out west in the company of Josie.

The brothers now will live by that code laid down by the patriarch. This is the most important line perhaps in the movie, with the exception of Wyatt's own at the end "Some say it didn't happen that way," commenting upon a flashback recounting his brand of law and justice in the wild cattle town of Dodge City.
