Redway receives a visit from Weatherby and the latter’s daughter, Alice. Redway and Bailey, the foreman, both fall in love with her. Weatherby, needing money, tells his circumstances to Redway, who offers aid. Weatherby suggests in return an alliance between his old friend and Alice, which is agreed to. Alice is induced to accept Redway. A treacherous half-breed overhears the plan to transport the money to the ranch, and leaves to incite the men of his tribe to waylay the party. On his way to camp he steals a bundle of cavalry uniforms from an army post supply wagon. These he uses as disguises, and his party of Indians, wearing the coats and hats of U.S. Cavalrymen, get close to the Redway party before being recognized. A fierce battle ensues. Meanwhile, Bailey, the foreman, with other cowboys, meets the supply wagon and recognizes the half-breed from the driver’s description. They ride to the Indian camp to arrest him. There they discover the discarded war-bonnets of the Indians and an old hat, once worn by the half-breed. Tom Bailey suspects the situation, and gathering up the war-bonnets for their disguise, the cowboys are away. In this way they manage to descend on the attacking Indians, and catch them between two fires. The half breed is attacked by Tom as he is about to kill Redway. Tom is wounded, but the rescue is accomplished. At the ranch again, Redway, who owes his life to Tom, observes a little love scene between him and Alice, and decides that the girl is not for him, but for his brave young employee.
