Jack Quick is a famed gunslinger and bounty hunter. Riding across the Kansas prairie, he happens upon a thirteen-year-old boy who is the last survivor of a wagon train heading west. Seeing a bit of himself in the kid, Quick takes him in, protects him, and teaches him to shoot.
In a town called Hendrix Fields, the lives of Quick and the Kid are turned upside down by a ruthless figure known as the Baron. In order to save the Kid, Quick must set out on his own to bring back the Baron's runaway daughter from a dangerous Pawnee warrior. But Quick has his own agenda and his own secrets.
