1940. A German submarine, U37, is known to be in Canadian waters off the east coast in the Gulf of St. Lawrence in having had a military encounter with a Canadian vessel. By the time the Canadian Air Force is able to locate U37, it is in Hudson's Bay off the Manitoba coast, the bombers able to hit and sink the sub killing all on board. What the Canadian authorities are unaware of is that six crew members were at the time on a covert land mission at a remote Hudson's Bay Company post in northern Manitoba to replenish the dwindling supplies on board. As such, the new mission of the six becomes to make it "home", the easiest path to head south to cross the border into the neutral United States where they would have amnesty. The longer the six remain in Canada, the more difficult it may be for them to make it out without capture as they leave a path of "Nazi-ism" in their wake.
