German sub-titled version of a Japanese film using a combination of documentary and feature material to cover the training of a Japanese Naval Air Force (JNAF) cadet prior to the attacks on Pearl Harbor and on the Prince of Wales and Repulse.

In summer 1936 the boy leaves home to become a cadet at the Naval Flying School of Tutiura. Here for the next three years he and his fellow cadets follow a rigorous course of outdoor instruction, including rugger, wrestling and other competitive sports designed to toughen their bodies and wills. On a brief visit home he learns that his mother recognises he now belongs to the Japanese nation rather than to her. After learning to fly he is posted to an aircraft carrier which takes part in the attack on Hawaii (Pearl Harbor). Torpedo-bombers and dive-bombers take off and attack the US Pacific fleet and airfield installations (model shots). Later the next month at an airfield in Indo-China Mitsubishi heavy bombers take off to attack the Royal Navy's Far Eastern fleet and although dangerously short of fuel they continue flying until they spot and sink the two capital ships Prince of Wales and Repulse (studio reconstructions with models). The stage is now set for Japan to bring her struggle for Greater East Asia to a successful conclusion.
