Pony Soldier (1952)

In 1876, Duncan MacDonald joins the new, 300-member Mounted Police in western Canada, just in time for a dangerous mission. It seems the Cree Indians, raiding across the border in Montana, took two hostages for their safe return to Canada. But MacDonald, with only scout Natayo to help, will need all his diplomacy and then some to extract the captives from the midst of a thousand Cree.
