This is the true story behind one of the most notorious names from the Golden Age of the Wild West. Who was "Billy the Kid"? A cold-blooded killer who murdered 21 men? Or an orphaned teenager driven to revenge the death of the only man who offered him a place to belong? Welcome to gang warfare--Wild West style.

In 1889, Wyoming erupts in the West's most brutal range war--a campaign of terror pitting the wealthy cattle barons against the homesteaders, and "the powerful" against "the people." From barn burnings to lynchings to gangland slayings, the barons will stop at nothing to defend their claim to thousands of acres of government land.
