Upon the death of his uncle, Ernest Selby, a young man from Iowa, inherits the Red Rock Ranch in Arizona. When he learns that the ranch's 20,000 cattle have dwindled to 6000 he suspects foul play. Ernest decides to go under cover in order to investigate these strange circumstances and lands a job on his own ranch, posing as a tenderfoot cowboy under a different name. As he makes friends and enemies and courts Annie, the daughter of the crooked foreman, Ernest learns to enjoy cowboy life. He knows that his charade must end eventually, but not until he can find the truth behind the disappearance of so many cattle—and win Annie's heart.
