Bob Huntley, U.S. mail rider, while in performance of duty through a dangerous territory, comes across an Apache Indian who has been thrown from his horse and had his leg broken. Like a good Samaritan, he takes him to camp and earns his gratitude. Later the Indian witnesses a murder and secures evidence by getting possession of the gun which fired the fatal shot. Still later Huntley is accused of the crime and about to be hung on flimsy evidence, when the grateful and acute Apache dashes on the scene, describes the murder, names the real culprit and frees Huntley, evening up the score of friendship.
