Movie Review: Saskatchewan (1954) or O'Rourke of the Royal Mounted

This film features Shelly Winters portraying Grace, a woman running from the law and Alan Ladd portraying Thomas O'Rourke of the Royal Mounted Police in Western Canada.  This story takes place during the time the Sioux from the United States had traveled north into Canada, after their defeat of Custer at Little Big Horn.  They were seeking more victories over white men and set their sites on the fort.  O'Rourke is dealing with a new Colonel, who doesn't really know about the Native Americans and treats all groups the same.  He threatens a long established friendship with the Cree, and then puts his own men in jeopardy by insisting they take a couple wagons cross country to a more fortified fort.  His men rebel under the leadership of O'Rourke, and although this saves their lives, they all end up in the brink.  They have to even go farther to assure the peaceful resolution without the Sioux Nation overrunning them all.
