 The cowtown of Ardmore is the headquarters of a gang of forgers, who by false documents are gaining control of Lonesome Valley. Rancher Steve Hanson (Buck Jones)suspects saloon keeper Jake Wagner (Walter Miller) heads the gang, and he secretly sends for government investigator Jim Lynch (Harvey Clark). Retta Lowery (Muriel Evans) goes to church with her young brother, Sonny Lowery (Dickie Holland), and finds the minister has been slain. Lynch, posing as a tramp, is thrown off the train and Steve saves him from Wagner confederate Peter Starr (Lee Phelps). Steve and Lynch search the church for clues, and find a tunnel under the floor. While Steve investigates the tunnel, Lynch is captured by Wagner s henchmen who plan to get rid of him by tying him to a runaway. Steve learns the tunnel merges into the saloon, but is discovered by Wagner. They fight and Steve knocks him out, and then rescues Lynch in such a manner that the crooks think he was killed.
