Jules Vincent, a French-Canadian
trapper (
Stewart Granger), while in a northern Canadian town, helps an attractive
Indian singer (
Cyd Charisse), fend off unwanted attentions from a drunken Max Brody (
Howard Petrie). The next day, Vincent sets off by canoe into the Canadian wilderness, taking the Indian girl up north to her tribe, now accompanied by a contrite Brody. When only Vincent and the Indian girl arrive at her
Chippewa village, Vincent tells the chief (
John War Eagle) that Brody had acted recklessly by trying to run the rapids, and that he then tried to shoot Brody in the shoulder to graze it and frighten him, but that he accidentally killed Brody when the canoe pitched wildly and spoiled his aim. Intent on avoiding arrest for murder, Vincent heads alone into the wilderness. After
North-West Mounted Police (NWMP) Constable Pedley (
Wendell Corey) arrives at the village on another matter, he learns about Brody's death. Pedley finds Vincent's cabin where the Indian girl tells him that Vincent is not a murderer. The NWMP Constable, however, is determined to bring Vincent in, saying running away makes the trapper look guilty. While on his trapline, Vincent finds a half-frozen Father Simon (
Morgan Farley) who had gone into the wilderness, to try to persuade the trapper to turn himself in. As Father Simon pleads with Vincent and utters his dying words, Pedley arrives to arrest Vincent. Despite Vincent's warnings that the weather will turn worse, Pedley takes Vincent into custody and starts a long trek back to the NWMP station. During the treacherous trip, Vincent tries in vain to overpower Pedley, whom he nicknames "Bebi.” When two lost trappers, Ruger (
Ray Teal) and Sloan (
Clancy Cooper) menace them, offering Vincent a chance to escape, Pedley observes that they will know "how good a man" Vincent is. Vincent proves his character by helping to overpower the trappers and send them away. Later, Pedley's leg is badly injured when he steps in a trap. Vincent helps him break free. They face an avalanche and a wolf attack, and an unlikely bond slowly forms between the two men. Despite Vincent's efforts, Pedley deteriorates, mentally and physically, or as Vincent puts it, "blanking out". Although he could abandon Pedley to certain death by freezing, Vincent continues to support the constable, handcuffing him to the sled to keep him moving. Eventually, he abandons the sled and allows the dogs to lead a delirious Pedley to the cabin. There, the Indian girl angrily asks Vincent why he saved the man who is sworn to take him to jail. Vincent tells her that he was saved by needing to accomplish the task of bringing Pedley to safety, and by his promise to do it. Pedley is so traumatized by the ordeal that he is unable to speak, despite Vincent and the girl's best efforts to revive him. Shortly thereafter, while trying to discreetly buy provisions for the men at the general store, the Indian girl is approached by Callahan (
J. M. Kerrigan), who hands her some tobacco free of charge and warns her that the local sergeant is looking for the two men. He tells her that "while some men" might think Vincent and Pedley might have become lost and died in the wilderness, he knows better. When she returns to the cabin, she finds Vincent still unable to break Pedley free from his fugue state. Vincent decides that the two men should travel down the river and brave the rapids in an attempt to shake Pedley out of his condition. The two men embark on a harrowing journey downriver in the canoe over treacherous rapids. Fearful for his life, Pedley finally begins speaking again, ordering Vincent to turn the canoe around, and when Vincent refuses, he tries to shoot him. The canoe capsizes, and the two men are thrown free, nearly drowning. As the two bedraggled men drag themselves to shore along the bank of the river, Pedley thanks Vincent. At a court hearing, Pedley testifies about the events, including the canoe trip, and the magistrate (
Holmes Herbert) orders Vincent released. As Vincent and the Indian girl depart, they give Pedley an orange kitten and tell him to "build a house around it." He names the kitten "Bebi," and with the kitten on his shoulder, watches the couple head down the river in a canoe, free. ==Cast==
