Enredo

Cheyenne takes a stage to transfer an outlaw to the brig at Fort Bridger. One of the passengers shoots a Shoshone and the rest bury him. When they reach the Relay Station, they find plenty of surprises waiting besides the angry Indians.

Cheyenne is assigned the job of transferring outlaw Johnny Eldorado to Fort Bridger for trial. He killed a man while stealing and hiding $10,000, which he refuses to give up, even in exchange for a more lenient sentence. As the Shoshone Powder Face is in the area and on the warpath, the Sheriff suggests Cheyenne take him by stage to have better protection to which Cheyenne agrees. There are four other passengers on the stage including two women and two men, including a Russian who calls himself "Count Nicholas Potosi", an arrogant and violent blowhard, who says he can take on anyone. The passengers are given the option to wait for a later stage but none do so. The Count feels he is being derided so he decides to ride on the top of the stage. "Potosi" wantonly shoots a Shoshone brave dead as the train passes. Cheyenne and the others are furious as they try to bury the brave's body well enough to ensure the Shoshone do not find his body too soon but this fails. They drive as fast as possible to the relay station but Powder Face and his braves, after suffering losses in the initial shootout, trap the train passengers along with the bigoted and repugnant station manager, his abused wife, and her Indian friend who has been attending "the white man's school" and is somewhat conflicted as to his identity. They are all stuck in the relay station with a short supply of water, food, and ammo, but lots of surprises and violence to come.—Updated by RM Sieger
