James Wynnegate is made executor of funds raised by members of his regiment for the families of men killed in battle. His cousin, the Earl of Kerhill, embezzles the funds, but Kerhill's wife Diana, with whom Wynnegate is in love, convinces the latter to take the blame and leave England in order to save the family's honor. Wynnegate eventually goes to Wyoming and buys a ranch using the name Jim Carston. He is saved from an attack by Cash Hawkins by the Indian maiden Nat-U-Ritch and he marries her when he learns that she is pregnant. Some time later, Diana comes West with news that Kerhill is dead, but that he had admitted his theft shortly before death. Nat-U-Ritch, knowing that her husband will send their young son Hal away, and hearing that she will be arrested for killing Hawkins, commits suicide. At the end, Diana embraces Hal.
