1879. The Civil War is over and the resulting economic explosion spurs the great migration west. Farmers, ranchers, prospectors, killers and thieves seek their fortune. Cattle growers turn cow towns into armed camps, with murder rates higher than than those of modern day New York or Los Angeles. Silver is discovered in Arizona.

They emerge as the earliest example of organized crime in America. They call themselves ‘The Cowboys’.
