U.S. submarine returns rom Pacific patrol. A American flag flies from the ice-coated conning tower of a U.S. Navy submarine as it comes into an Arctic port after a campaign against enemy shipping in the Pacific. Japanese flags indicate that the submarine has sunk three enemy warships and two merchantmen. The broom attached to the periscope is the crew's symbol of a clean sweep of all enemy vessels encounterd.
