 An Apache graduate of Harvard is a new Federal Marshal looking for the Apache who allegedly burned down a house, killing an elderly couple. He discovers that the real perpetrator is a white man in North Fork, and against the advice of Lucas, he is determined to make the arrest. The men at the saloon despise all Indians, and the arrest attempt produces an angry mob in the street challenging the authority of the Apache marshal and Marshal Micah Torrance. The scene nearly results in gunfire when Lucas jumps on a handy buckboard and delivers a speech shaming most of the mob into submission. The leader of the mob is also arrested by the Apache marshal when it is revealed that he ordered the burning of the house.
