Somewhere in Wyoming Territory, the office of the local newspaper, Rock River Advocate, and its editor and proprietor, Richard E. Ross, gets harassed by outlaws.

Dick publicly denounces Sheriff Luke Graham, accuses him of complicity with several crimes, including bank robbery and murder perpetrated by the outlaws, and vow to replace him with his friend, real estate agent Jim Dawson.

As he does this, Luke, who had been eavesdropping the discussion, enters to tell him about a letter from Dick's daughter, Grace, saying she would move from Kansas City, Missouri, to Rock River to help out her father's newspaper.

As Grace is traveling to Rock River, her stagecoach is attacked by bandits while its driver is wounded, but Crash and Dusty arrive on the scene, scare the outlaws off, and escort her to Wyoming.

After a fight, the Range Busters capture Jim and the outlaws and discover that it took so long yo find them because their horse's shoes were applied backwards.
