Buck and his older brother, Ray, quit the Rebel army in 1863 and go their separate ways. Ray seeks vengeance on those who killed their parents, while Buck has had enough of killing and drifts for eleven years until he reaches Rymansville.
He immediately runs into trouble with the law, a powerful rancher, the rancher’s sons and a local outlaw gang. After going to the rescue of a young lady he is arrested by the marshal who mistakes him for his brother, now a wanted fugitive.
Buck is forced to use his wits, his gun and his fists as he struggles against the odds to survive. Who can he turn to for help? Whose side is the law on? Will he ever be able to settle down with the woman he loves? And will he meet his brother again?
