In the twenty-sixth year of the Republic of China, Wuzhen, a water town in the south of the Yangtze River, was shrouded in flames of war. Shen Yanqiu, a descendant of a century-old traditional Chinese medicine family, lived a peaceful life. However, due to the Japanese invasion, he witnessed the suffering of his compatriots and the destruction of his home. She put down the medicine grinder, used the silver needle as a blade and the medicine box as a shield to treat the wounded, pass on information, and fight side by side with the patriots in troubled times. From a weak woman to an anti-Japanese pioneer, she used the benevolence of a doctor and the justice of the nation to write a soul-stirring song of salvation in the flames of war, showing the perseverance and feelings of the Chinese people in the face of national disaster.
