Returning to his father's cattle ranch after the excitement of serving in combat overseas, Bud McGraw becomes restless, and his father decides to send him to an old friend who commands the Border Police in Texas. On the way he meets Peggy Hughes, accompanying her Uncle Graham, a customs inspector, and he retrieves her hat from the rails of a train. At the headquarters, numerous scrapes and fights win him the admiration of, and friendship with, the men. Lazaro, a Secret Service agent, invites Mrs. Graham and Peggy, who are staying at the border station, for an automobile ride, and they are captured by bandits and held for ransom. Bud and his pals deliver the ransom and discover that Lazaro is the bandit chief. Lazaro refuses to release Peggy, but a jealous rival, Nita de Garma, causes his downfall and shoots him as the Border Police arrive to rescue the party.
