In November 1944, a German U-boat slipped into Frenchman Bay, Maine, and put two spies ashore in a snowstorm. One of them was an American. Four days later, the same submarine torpedoed the Canadian freighter SS Cornwallis in the Gulf of Maine. Forty-three of the forty-eight men aboard were killed.

The spies' story, Operation Elster, is usually told as a comedy about agents who blew their money in New York nightclubs. This documentary puts both halves of the story together: the mission, the men who noticed footprints in the snow, the sailors who paid the price, and the volunteer divers who finally found the Cornwallis nearly 400 feet down in July 2026.
