In Nanjing in 1934, Shen Huaijin married Huangpu officer Gu Shoucheng in an arranged marriage. I thought it was destiny, but I unexpectedly found love. Her husband is her husband and her mentor, teaching her how to read and showing her a wider world. However, the war broke out suddenly in 1937, and the sweet life came to an abrupt end. On the eve of the fall of Nanjing, Gu Shoucheng sent Huaijin to his friends to Chongqing, but he decided to stay behind and ended up with blood splattering on Yuhuatai.
The sad news that her beloved died for her country and the blood-stained Yuhua Stone shattered Huaijin's world and ignited her flame of revenge. She is no longer a dodder in need of shelter, and resolutely joins the intelligence system. In 1941, she changed her name to "Su Wenjin" and returned to occupied Shanghai as a new widow, dealing with senior Japanese and puppet officials and spies.
In the dances, salons and dark alleys of the isolated island of Shanghai, she used her wisdom and courage to obtain key information time and time again. She refined her selfish desire to avenge her husband into a firm belief in serving the country and the people. Like a phantom in the dark night, she experienced the most dangerous traitor crisis on the eve of victory, finally completed the mission and witnessed the surrender of the invaders with her own eyes.
When the whole city reveled in victory, she held the rain flower stone in her hand to comfort her deceased husband, and then quietly disappeared into the sea of people and rushed to a new battlefield. She woke up from an arranged marriage, was reborn in a broken era, and ultimately transformed her personal tragedy into an unsinkable national belief.
