The stranger without a horse seemed to appear out of the desert sands. Unwilling to leave any man afoot in the wilderness, the stage driver lets Riley swing aboard to the disturbance of Eleanor Gates, a young woman travelling west to meet her army officer fiance. But Riley soon finds himself uneasy as he recognizes one of his fellow passengers as the leader of a renegade band. The comanchero leader has his eye on Eleanor and the gold the stagecoach is carrying, and a gang of thugs is waiting along the trail. Only Riley stands in their way. Can he stop the raid and save Eleanor?
