Texas Ranger Chic Shelby is sent to capture James Trammel and his son, John--two outlaws hiding in the mountains who are victims of a cattle war. Shelby tricks John, who has killed a cattleman, into believing he is an itinerant preacher by delivering a sermon on eternal love. John comes forward to be arrested, obviously moved by Shelby's sermon. Meanwhile, Sam Hervey betrays John's sister, Susie. Fearing her father's wrath, Hervey seeks out James Trammel, shoots him, and blames the crime on Shelby. Shelby clears himself by capturing Hervey, John is acquitted, and Susie ends her own life by drowning.
