Mix is Grant Malvern, a rancher who befriends scientist Quentin Durant (Tom S. Guise) after rescuing him from a trio of Chinese crooks. The crooks want to find Durant's Arizona gold mine, and the map to the location is contained in a pair of rings. After the crooks track down Durant and kill him, one of the rings winds up with Durant's daughter, Helen (Adams), and the other falls into Malvern's hands.

As a boy, Tom Morley, was forced to watch the killings of his foster parents and the abduction of his foster sister. When he reaches manhood he joins the Texas Rangers and becomes very good at tracking down outlaws; whereby, he is given the nickname "The Falcon". He finally tracks down his long lost foster sister who has become a spy for the outlaws.

This George O'Brien western is based on a novel by Max Brand, previously filmed as the 1920 Tom Mix vehicle The Untamed. Cast as devil-may-car Whistlin' Dan Barry, our hero rides into a passel of trouble in a wide-open town. Warned to leave the premises or else, Whistlin' Dan refuses to do so, sticking around long enough to whomp villain Jim Silent (Mitchell Lewis) and romance heroine Kate Cumberland (Louise Huntington).
