Lt. Jasper Hobson and other members of the Hudson's Bay Trading Co. and his team along with the company's guests, Mrs. Paulina Barnett and Thomas Black travel through the North West Territories of Canada to Cape Bathurst on the Arctic Ocean. At Cape Bathurst, Hobson intends on creating a new trading post for the company, Paulina Barnett is along for the adventure and Thomas Black intends on viewing a solar eclipse during the summer of the following year. The party establishes their outpost before winter sets in, but when spring arrives, nearby volcanic activity triggers an earthquake, which the colony survives; however, a startling revelation is revealed later in the summer when Thomas Black tries to observe the total eclipse.
