When naval Lieutenant Phil Bowen encounters his friend, Air Forces Captain Grover, he inquires as to what Grover's aerial reconnaissance team is doing to protect ships from attack by submarine. Grover introduces him to Captain Smith, an expert at photographic intelligence. The two men explain to Bowen just how aerial photographic reconnaissance works and how their work in the air and on the ground is helping win the war even at sea.
