The story takes place during the puppet Manchukuo period under the rule of the Japanese invaders. Chang Qing (played by Wang Likun) is a patriotic doctor. She has long used her position to secretly help the Anti-Japanese United Army raise medicines, which even her husband Dingbang (played by Yu Hewei) who lives with her day and night does not know. The couple discussed and decided to leave Manchuria and live in the interior. At this time, Chang Qing learned that the enemy would have a large number of arms entering the country. She asked Dingbang to go first, and she stayed to stop it. Dingbang, who was unaware of the situation, did not understand the purpose of Changqing staying alone, and was very doubtful. Dingbang was originally an anti-Japanese faction in the national army. He saw more and more clearly the Kuomintang's intention to pretend to resist Japan and really suppress the Communist Party.
