Wyatt Earp was too young to serve in the Civil War... but that didn't stop him from trying. When Wyatt's three oldest brothers go off to fight for the Union, 13 year-old Wyatt tries to runaway from home to join them. And each time, Wyatt's severe father stops him.
After wagon-training out to California, Wyatt's father moves the family all over The West searching for an opportunity to strike it rich... but he never does. Wyatt falls in love and marries into a good family, but his wife dies in child birth, leaving Wyatt devastated. It drives him over the edge, leading him into a wayward life through the roughest frontier towns of The West. His father had been a lawman, and Wyatt follows in his path at first. But Wyatt believes he's destined for something greater... and he thinks that by playing by the rules and enforcing the law, he'll be able to achieve this dream.
But Wyatt learns a hard truth in Dodge City. He finds a natural talent for keeping the peace during the violent cattle season, but as Wyatt watches the outlaws he arrested freed at the behest of railroads in need of gunmen... he gets fed up with the culture of privilege and corruption. When his brothers go out to Tombstone to strike it rich in the silver mines, Wyatt thinks he's finally found his opportunity.
Wyatt swears off his life as a lawman and vows to only work for himself, as a businessman. But when Wyatt and his brothers fail to strike it big in silver, the Earp Brothers quickly go back into the only business they know: law enforcement. The Earps' close alliance with Wells Fargo makes them the ideal face of the law in Tombstone, but when Wyatt finds himself at odds with a murderous band of gunmen, he crosses the line between lawman and outlaw by going vigilante. The OK Corral and Wyatt's Vendetta Ride come to the attention of the White House. His friends abandon him, and after cleaning up Arizona Territory, Wyatt finds himself hung out to dry.
