The synopsis states that:
There is a last bloody battle between Paleface's men and the few old Indians, supported, however, by our three heroes. Sakura's sacrifice of his life brings them victory and in the end the sheriff and the Swiss part like old friends. Sheriff Carson, disillusioned at the collapse of all the things in which he had always believed, threatens Butler, robs him of the million dollars and kills him; but while he is making his escape the Swiss lies in wait for him and robs him of the booty once more for the last time.
However in the film I just watched, Sakura does not die in the fight, but saves the lives of both men, and stays to live in the village with the native Americans. The Sheriff earns his money by shopping in the corrupt banker and plans to run away with an attractive woman, but is stopped by Swiss and the Sheriff's family, leaving Swiss to drive away with the woman, and the Sheriff to go home with his wife and dozen kids.
