Written on the 80th anniversary of the victory of the Anti-Japanese War - the rich second-generation male protagonist of the Air Force and the ill-fated doctor female protagonist met again in Hangzhou before the Anti-Japanese War. The heroine and the male protagonist had two completely different professional concepts and values that collided many times (rescuing the Japanese, germ warfare, air defense and rescue propaganda, etc.). Although the heroine suffered the blow of losing her close relatives and friends, she still joined the anti-Japanese war as a field doctor and helped the hero win an important battle. The heroine overcame the knot in her heart and stayed with the hero. After the heroine retreated to Wuhan, she gathered various social forces, sought assistance from the International Red Cross, exposed the crimes of the Japanese army, and treated refugees. When Wuhan fell, the surviving young people jointly assisted in the evacuation of Wuhan, playing a heroic elegy in which the army and the people worked together to defend against foreign enemies.
