Charlie Wooster and Barnaby West have the task of escorting Dr. Katy Piper and her daughters to join up with the Chris Hale wagon train. Barnaby is forced to shoot a masked bandit who has hijacked the Piper wagon and ends up killing the bandit. The bandit turns out to be a teenage boy, and though Barnaby is cleared of any wrong doing, he carries the guilt of the killing and the judge tasks him with telling the boy's mother of the death. His guilt is manifested in the stigma of a constantly bleeding gun hand, though there is no physical wound. Barnaby ultimately quits the train when it's time to visit the dead boys mother. The news has already reached her and she, along with the rest of the town, are ready to kill Barnaby for what he's done. Katy Piper and Cooper Smith arrive in time to prevent Barnaby from being killed but not before the dead boy's twin is shot. With the young man weakened by blood loss Barnaby volunteers to be the donor in a radical procedure called blood transfusion, despite Dr. Piper's warnings that it could be fatal to both. It's Barnaby's chance at redemption or a sure trip to the grave.
