This film is about the signing of a peace treaty between the United States and Indians as far back as 1887, promising to help Indians who are suffering from various problems such as natural disasters, diseases, food shortages and so on, and are stationed in the Oklahoma Reserve. But the United States government ignored the pact, so the Cheyenne chief decided to return to his original place of residence with abundant agricultural products. In this way, it broke the agreement, caused conflicts between the army and the Cheyenne, and plunged the United States into instability and unrest. The friction between the Americans and the Indians was increasing day by day, and fortunately, an officer asked the Secretary of the Interior to resolve the conflict and designated the original place of residence of the Indians as a reserve, and there was finally peace between the United States and the Indians. This film is an epic film made by the famous director John Ford. Under the exquisite description of the director, human dignity is fully expressed, and the historical background at that time is fully interpreted in a realistic way.
