The Vanishing American

History, as portrayed in this film, has been a succession of conquests of stronger races over weaker ones. As played out on the stage of Monument Valley, long ago, tribes of Indians defeated the ancient cliff dwellers; then came the Europeans to conquer the Indians. Now, in the early 20th Century, a tribe of Navajo live on a reservation overseen by an Indian-hating agent, Booker. He and his men steal the best Indian horses for their own profit. Nophaie, a tribal leader, complains to Booker's higher-ups, but he is unable to gain fair treatment from the whites. When World War I breaks out, an Army captain comes west in search of the horses that Booker was supposed to have bought from the Indians for a fair price. Marian Warner, the teacher at the Indian School, has befriended Nophaie, teaching him to read; she convinces him that the Great War is a fight for a more just world, and that, when that world comes, the Indian will be better treated. Nophaie not only brings horses for the Army, he and many other Indians enlist, and distinguish themselves in battle. But when they come back after the war is over, they find life for Indians even worse than when they left. Surely, they feel, it is time to fight back. But Nophaie is not so sure. - IMDb
