Canaan, a mysterious gunfighter left nearly blind from Civil War combat, roams through Mexico with a baby he has sworn to protect. On his way to a town where a family will supposedly adopt the baby, Canaan passes through a border town where U.S. Cavalry officers assigned to deliver a shipment of silver are under attack from bandits. With some reluctance, Canaan steps in to help the soldiers.

Canaan:
I can't see you, I can't hear you. You smell like shit.

Factual errors: Canaan carries two Colt Single Action Army 6-shot revolvers, which carry a maximum of six rounds each. However, in one shooting scene, he fires eight shots from one pistol, then draws the other and fires only four rounds. He then states that the second revolver is empty.
