The story follows Connie Carl, a young woman who returns from Eastern schooling to take charge of her inherited New Mexico ranch and finds staff scattered and a foreman whose loyalties are uncertain. As she seeks to restore order she faces betrayals, schemes by a rival, a daring kidnapping and rescue, cattle theft, a night prowler, and a stampede, culminating in a dramatic roundup that tests her courage and resourcefulness. The narrative balances frontier action and mystery with a coming-of-age arc as she reclaims leadership of the ranch.
