A young boy witnesses the slaughter of his family by a ruthless gang of horse thieves. Meanwhile, a convicted swindler en route to prison wins an unexpected reprieve when the marshall escorting him (CALEB POWLER) drops dead. The prisoner takes the marshall's name and, reaching Curtis Wells, impersonates him. In doing so, he has the opportunity to redeem his past cowardice - until Newt recognizes that he's indeed an imposter. In a climatic siege, Caleb actually gets the chance to prove himself, winning Newt's respect and the freedom he'd long since given up on.
