Bob Camp, a ranch foreman, saves his chore boy, Tony Mendoza, from a beating at the hands of gambler "Goldstud" Hopkins; Lone Badger, a renegade Indian, intervenes and holds them up, and Goldstud escapes. Having wronged Marie, Tony's sister, the gambler then attempts to win the favor of Rose Martin, daughter of the ranch owner, who is loved by Bob. While Bob is deputized to search for Lone Badger, Marie tries to induce Goldstud to marry her; when Tony attacks the gambler, Rose accidentally kills Goldstud. Bob suspects Marie, but he is interrupted by a battle between the posse and the cornered Lone Badger. Marie confesses to killing the unfaithful Goldstud, but she is freed by the "unwritten law."
