The war of resistance against Japan reached Jinling. In order to prevent the Japanese army from looting the tombs of the Han Dynasty, Jinling University archaeologist Xu Mingshi went to the Qinhuai River and met Fusang, a singing girl who held the secret key to guarding the tombs. When they first met, he despised her for being frivolous, and she teased him for being bookish and arrogant, and the two were tit-for-tat.
But when he saw her singing "Chu Song" in a lost ancient tune to avoid trouble, and using her body to block bullets for him, he realized that this woman who was dealing with sex was actually a descendant of the tombkeepers who had guarded the royal tomb for more than 1,700 years.
Civilization and barbarism confront each other, prejudices melt away in shared dangers, and love grows in the protection of life and death. Hand in hand, they used archaeological wisdom and family loyalty to build the strongest barrier for a royal tomb and a civilization in troubled times.
