Chris has picked Duke to escort Hiram Winthrop and his wife to San Marcos where he is taking over as the new Indian Agent for the Apache reservation. He has offered Duke a job as his Deputy Indian Agent given Duke's experience. Hiram is an Easterner with his own ideas of how the Apache should be treated. Duke accepts the job and tells Chris he will not be returning to the train as he wants a steady job where he can put down roots. Chris grudgingly accepts his resignation but Bill tries to warn Duke about Hiram which Duke does not take kindly to. After they reach San Marcos, Hiram and Duke learn the Army has abandoned the local fort, the main rancher Riatt hates the Apache, and the Apache are starving as they have not received the beef that was bought for them from Riatt. Hiram's ideas on the Apache becoming farmers are rebuffed by the Apache Chief Two Arrows. Duke and Hiram find themselves in the middle of a budding Indian War.
