Shortly after arriving in the West, James Van Dyke Moore, an Easterner fleeing from a soured love affair, has his courage tested when "Ace High" Horton, the town bully, threatens to take over the family mine. Forced into battle, the tenderfoot stands his ground against Horton, an act that impresses pretty Mollie Anderson. One day, Robert Forrest arrives from the East with Verda, his bride, who is Moore's former lover. While Forrest is off inspecting his mines, Verda and Horton become lovers and plan an elopement, but upon Forrest's return, Verda informs him that she is leaving town to escape Moore's advances. Because he has vowed not to reveal anything about their past affair, Moore is unable to defend himself. That night, Forrest sees Verda riding away with Horton and shoots him, but Moore is accused and arrested. Through the intervention of Mollie, Moore is released in time to intercept the couple in the desert. After disposing of Horton, Moore returns Verda to the town, whose angry citizens drive her back into the desert, and then proposes to Mollie.
