In 1940, the Chinese battlefield, one of the most important battlefields in the anti-fascist war, entered a stalemate between China and Japan. In order to speed up the invasion of China, the Japanese army was secretly planning a horrific bacteriological warfare, so the Japanese army decided to speed up the research of bacteriological weapons. Jin Shenshui, a doctor who escaped from the Nanjing Massacre alone, drifted to Taohua Town, a "Baojia Model Area" established by the Japanese army. Jin Shenshui accidentally saved the biochemical expert Bai Dayi, but unexpectedly it was the beginning of a series of turbulent events. The veil of Taohua Town's prosperity was gradually lifted, and inhumane bacterial human experiments, terrifying and deadly human brain control drug experiments, etc. surfaced one by one. Under the guidance of the party organization, Jin Shenshui skillfully dealt with the cunning enemy and went through life and death several times. In the end, under the cover of Lin Yingying, a female doctor who also had a grudge against the Japanese army, Jin Shenshui joined forces with the New Fourth Army and the guerrillas to completely eliminate the Japanese army in Taohua Town, and at the same time exposed the various crimes of the Japanese army using human bodies for bacterial experiments. Jin Shenshui also grew from an ordinary patriotic youth to an outstanding Communist Party member.
