Cynthia Moore, daughter of Colonel Moore, who is the commander of a cavalry post near the Mexican frontier, is much beloved by two junior officers in her father's command. They are Lieutenant Robert Bright and Lieutenant Arthur Hartley, both graduates of West Point, where they had been rivals during their Academy Days. This rivalry, which had been friendly at West Point, became very bitter when they were both assigned to Col. Moore's post and met his attractive daughter, and the true nature of the two men began to assert itself.
