Roald Amundsen's polar ship Maud spent 85 years sunk in the ice of Canada's Northwest Passage after being seized by creditors and abandoned near Cambridge Bay. Built with a rounded "bathtub" hull designed to let pack ice lift the vessel rather than crush it, the Maud was meant to drift across the Arctic Ocean the way Amundsen's earlier ship Fram had, but financial ruin ended the plan before it began. This film follows the engineers and divers of the Maud Returns Home project as they plan and carry out the salvage, wrapping the wreck for a slow raise from the seabed and the long tow back across the Atlantic to Norway. Underwater footage shows the hull still largely intact after decades submerged, and interviews with the recovery team lay out the technical problems of moving a century-old wooden ship without it falling apart in transit. The film treats the recovery as an engineering story first, with the history of Amundsen's failed expedition as the reason anyone bothered.
