A group of Sioux come to shelter in Canada from the Indian wars in the United States following Custer's last stand at the Battle of the Little Bighorn. They are given permission to remain by the Canadian government represented by three Mounties. Caucasian Indian-fighters from Montana searching for 40 stolen horses discover the Sioux settlement and mistakenly assume their horses are theirs. In the white men's surprise attack they murder many Indians, steal many horses, and kidnap an integrated white young woman recognized as having been kidnapped in a raid years earlier. The Mounties promise justice, track, capture, and begin the week-long ride to a trial at court. During the week tables turn back and forth, backstories shared, some discussion about American gun culture and violence, and the woman is killed. Eventually the Caucasian Americans are lured to what may be their lost horses but a stampede erupts and the Sioux manage drive the white men over the cliff like buffalos to their death. Without a shot fired and the deal maintained the Sioux remain in Canada while the Mounties return to their fort where the senior will finally retire.
