Homesteaders are moving into the valley settled many years ago by rancher Craig Dolan. He wants to keep them out by legal means but his nephew Bart brings in outlaws to drive them out. The Lone Ranger is on hand to help the homesteaders battle Bart's men as he overcomes traps, ambushes, burning buildings and other obstacles in his attempt to bring peace to the valley.
