Judge Garth and Betsy returning from cattle meetings in Montana are two of eight passengers on a stagecoach which is attacked during a rest stop. Besides the Garths the passengers include an older couple, a young couple, and two men one of who is a personable and exuberant sewing machine peddler. They race to the Sundown way station that is heavily fortified but the driver is killed on the way there. The way station was once a Montana Territorial Prison that has been decommissioned. The station master is an ex prisoner who suffers from battle fatigue. Judge Garth learns from the gang leader that they want a man named George Wilson but no one in the group uses that name. Garth is able to deduce who Wilson is and Wilson comes forward telling them that he used to be part of the outlaw band but betrayed them and they want revenge. With emotions high the group narrowly votes to protect him. After a gunfight in which both sides takes losses, the gang applies greater pressure forcing the group's hand amid their internal squabbles over what to do.
