Ranchers on the California-Nevada border are harrassed beyond endurance by the combined efforts of Slade, leader of a gang of rustlers, and Brand, who runs a "Protective Association"; and Reingold, the leader of the holdouts, finally goes to the capital for help. Happy-go-lucky drifters Dan Wright and Jack-Knife arrive on the scene in time to prevent Brand's capture of Reingold, and they generally frustrate the rustlers until the Cavalry arrives to round up the gang.
