Action in the North Atlantic

After their tanker is torpedoed by a U-boat, a merchant marine crew survives at sea before returning to duty on a new Liberty ship bound for Murmansk. The film dramatizes the dangers merchant sailors faced running the Atlantic gauntlet to supply the Allies.

American and Allied merchant mariners suffered heavy losses to U-boat attacks, particularly during the 'Second Happy Time' of 1942, while Lend-Lease convoys to the Soviet Union via Murmansk faced constant peril.

Made as wartime propaganda with Navy cooperation, the film glamorizes merchant marine heroism but reflects genuine convoy dangers of the period.
