That night Sam and his wife, Mavis (Aline MacMahon), reveal more about Yancey's past as a cowboy, a gambler, a gunman, and a lawyer. They scoff at his being a rancher. They hope to pass the legacy of the paper on to him. At noon on 22 April 1889, 50,000 settlers race across the prairie on every conceivable form of transport. There are 2 million acres—enough for 12,500 homesteads. Tom falls, and Sarah claims a dry, worthless patch a step across the line. Pegler is trampled to death, and Dixie beats Yancey to the land he wanted, so he asks Jesse to stay and help him run the paper. The new town of Osage consists of tents and half-built storefronts; the Oklahoma Wigwam is selling briskly. Yountis and The Kid terrorize Levy in the street; Yancey tries and fails to persuade the Kid to change. One night, Yountis leads a mob in lynching Ben. Yancey arrives too late, but he kills Yountis and brings Arita and her baby, Ruby, home. Meanwhile, Sabra has given birth to a boy whom they name Cimarron, Cim for short. Four years later, Osage is thriving. On Yancey's advice, Tom has built an oil-drilling apparatus. He is a laughingstock. Wes, Hoss and The Kid, wanted outlaws, try to rob the train in town . Hoss is killed, and Wes and the Kid run to the schoolhouse, where Wes seizes a little girl as a shield. The Kid pulls her to safety and is shot. Yancey kills Wes. When Yancey destroys the $1000 reward check, Sabra is furious: He never thinks of their son's security. Yancey is ecstatic when a news service telegram announces the opening of the Cherokee Strip. He tells Sabra: They are going. She says No. He goes. Five years later, Tom is still working on his oil well. A duffel bag arrives from Yancey, from Alaska, with nothing in it but a polar bear skin. Yancey joins Roosevelt in Cuba and eventually "Osage's Own Rough Rider" returns. Sabra—who was planning to scold him—runs into his arms. Cim also forgives him. Then Tom bursts in, covered in oil. Oilfields spring up, marking the passage of years.
