 "Cash" Karger (Wallis Clark), crooked political boss of Casper County, plots to usurp the lands and cattle of the local ranchers. His first move is to build a cabin directly across the Collins (Frank LaRue) cattle trail, blocking the way to the water hole. Collins cowhand Tom Devlin (Buck Jones) goes to the office of the Casper News to demand editorial fair play, only to learn that its pretty editor, Mary Middleton (Barbara Weeks), must follow Karger s orders or pay him $2000 due on a mortgage. He resolves to raise the money and purchase an interest in the newspaper. There is a $2000 reward offered by Karger for the capture of rustlers, which he has to pay when Tom brings in Burke (Al Smith), a Karger henchman, caught rustling. Tom learns that the cabin blocking the trail is the home of Mary and her mother (Mary Carr), and he moves the women to the Collins ranch. Karger supervises the burning of the Middleton cabin and the killing of Burke, and the blame is placed on Tom who is arrested. Unknown to Karger, Burker had planted evidence implicating him in his jail cell, which Tom discovers. Tom, with the aid of his horse Silver, escapes jail and routs Karger and his henchmen who are raiding the Collins ranch.
