Plot

In 1943, at the height of the World War II Battle of the Atlantic, Captain Pat Banyon, skipper of the fishing trawler Daniel Webster, unloads his catch in his home port of Gloucester, Massachusetts. He reluctantly agrees to transport Margaret McLean to Trabo, a small community in Newfoundland. Shorthanded, he hires Danish sailor Konrad, and the Daniel Webster sails for the Grand Banks fishing grounds. Once at sea, another Dane, Holger, reports that the radio has been sabotaged. As Banyon knows all of the crew well except for Konrad and fellow Dane Holger, he suspects one of them or even Margaret of being a German agent.
