As the
Canadian Pacific Railway makes its way through the western frontier of Canada in the early 1880s, railroad workers and settlers come under frequent attack by Indians who resent the white man's encroachment on their land. One such attack on a wagon train leaves only one survivor, a young girl named Susannah Sheldon who is found by a mounted patrol in the command of Inspector Angus "Monty" Montague. Susannah is taken to the post where she is cared for by Monty and his friend, Pat O'Hannegan. They do their best to help her overcome her ordeal. Some time later, Vicky Standing arrives from Toronto to visit her father, the Superintendent. Monty is immediately enchanted by the beautiful woman. The blossoming romance sparks a rivalry in Susannah and Harlan Chambers, the head of the railroad camp. The Indian attacks resume when renegades steal horses from the railroad camp. One of the friendly Indians, Chief Big Eagle, promises to track down the renegades and deliver them to the camp. As a show of good faith, the Chief leaves his son, Little Chief, at the post. Little Chief teaches Susannah Indian ways. While the two are out riding, they run into a renegade, Wolf Pelt, attempting to sell his stolen horses to Chambers. The two argue and Chambers threatens the Indians with extinction. Wolf Pelt returns to his tribe and uses Chambers' threats to demand that the tribe go to war against the Europeans. That night, Wolf Pelt raids the post to retrieve Little Chief and kidnaps Monty. Soon after, Big Eagle sends a message demanding that the railroad abandon the area or they will kill Monty. Susannah searches for Monty; she approaches the Indian camp, she is taken prisoner. As the tribe prepares to burn Monty at the stake, Susannah escapes the
teepee and appeals to Big Chief, accusing Wolf Pelt of inciting Chambers by stealing his horses. Wolf Pelt denies the charges. To determine who is telling the truth, Big Chief uses the stick of truth that will point to the liar. When the stick drops towards Wolf Pelt, Big Chief frees Monty and offers him and Susannah his peace pipe. ==Cast==
