 Matt, Doc and Festus are on a train in the snow-capped Rockies. Indians stop the train by blocking the tracks in front and behind the train. Someone aboard sold the Indians a bad batch of whiskey that has killed or blinded those who consumed it. The Indians want the guilty turned over to them and will attack in the morning. Matt has his hands full keeping order as the train occupants want to take justice into their own hands. Matt makes a desperate decision. Festus will create a diversion while Matt gets off the train and heads to the nearest telegraph station, which is miles away. The ploy works but three Indian braves, not fooled by it, are in pursuit of Matt.
