Output: Early in World War II, U37, a German Uboat makes its way to Canadian waters and participates in fictional antishipping activities similar to those of the later Battle of the St. Lawrence. The Uboat evades RCN and RCAF patrols by moving north. A raiding party of six Nazi sailors are put ashore to obtain supplies but soon after, the Uboat is sunk in Hudson Bay by RCAF bombers. The six attempt to evade capture by travelling across Canada to reach the neutral United States and return to Germany. Led by Lieutenants Hirth Eric Portman and Kuhnecke Raymond Lovell, the small band of sailors encounter and sometimes brutalise a wide range of people. The band steadily diminishes as one by one they are killed or captured. Initial victims of the Nazi sailors are the Eskimo Nick Ley On and a FrenchCanadian trapper Laurence Olivier. When a floatplane is dispatched to investigate to reports of their arrival at a Hudsons Bay Company trading post, the Germans open fire, gunning down the pilot and some of the local Inuit. The Nazis steal the aircraft and take off to fly south, but not before one of the sailors is shot and killed by an Inuit. The floatplane runs out of fuel and crashes in a lake in Manitoba, killing Kuhnecke. The Germans encounter and are welcomed by a nearby Hutterite farming community. The Nazis assume them to be sympathetic to the German cause, but Hirths fanatical speech is rejected by Peter Anton Walbrook, the communitys leader and even by one of the fugitives, Vogel Niall MacGinnis, who comes to the aid of Anna Glynis Johns, a teenage girl. Vogel, who would rather join the community and ply his trade of baker, is tried by Hirth and summarily executed for desertion. The dwindling band arrive in Winnipeg and sell some field glasses for food. Hearing that the police are watching the border, Hirth decides they will travel to Vancouver to catch a steamship for neutral Japan. Knocking out or murdering a motorist for his car, Hirth, Lohrmann and Kranz flee west, having killed eleven civilians in all. Kranz is arrested by Canadian Mounties at a parade at Banff, Alberta. The two remaining men try to walk across the Rockies. They are welcomed at a camp by a writer named Philip Armstrong Scott Leslie Howard who takes them for lost tourists, but they turn on him, destroying his books and paintings before fleeing. Scott and his men pursue them. Lohrmann finally rebels against Hirths leadership, knocks him out and takes off by himself. Lohrmann is cornered in a cave. Scott is shot, but enters the cave and beats him up. Hirth is the last fugitive. The story comes to a head with a confrontation between him and Andy Brock Raymond Massey, Canadian soldier who is absent without leave, aboard the baggage and express car of a Canadian National Railways train near the American border. When Hirth learns that the train has crossed into the United States at Niagara Falls, he surrenders his gun to a customs official and demands to be taken to the German embassy. Brock explains that Hirth is wanted in Canada for murder, but while the U.S. border guards are sympathetic to Brocks plea, they cannot find any official reason to send Hirth back. When Brock points out that Hirth is not listed on the freight manifest, the Americans are happy to use this pretext to send the car, along with Hirth and Brock, back to Canada for improperly manifested cargo. The film ends with the trains reversing to Canada and Brock about to pummel Hirth in the baggage car.
