On a rainy night on the Bund, Shen Nian, associate professor of the History Department of Hujiang University, clutched the gilt pocket watch left behind by his grandfather. At the moment predicted by his grandfather's diary, he was involved in Shanghai in 1936. The familiar skyscrapers have turned into low arcades, and steamships are cruising on the Huangpu River. The jeans and down jacket she is wearing seem out of place in this era.
At the time of crisis, she met Cheng Yiqing, the son of a banker who mysteriously disappeared from the historical archives. The scar on his left eyebrow hides an unknown story, and his eyes are as sharp as an eagle. He saw through her lie about being an "abroad student in Paris", but brought her back to her apartment on Xiafei Road; he dealt with the Japanese Chamber of Commerce and secretly funded the anti-Japanese forces, and the "Made in China 2022" button Shen Nian carried with her had already exposed her origins.
The hands of the gilt pocket watch ticked, and a warning appeared on the inside of the watch cover: "Don't change history, the moon is full." But when she saw that the Cheng family was in crisis due to the collapse of rubber investment, when she discovered the financial conspiracy of Japan's Zhengjin Bank, and when she danced with Cheng Yiqing to the melody of "Tuberose", she could no longer stay away.
The trajectory of history was deflected because of her, and Cheng Yiqing's fate was rewritten because of her. From their first encounter on the Bund together on the financial battlefield, from the ambiguous exploration in the storage room to the life-and-death decision, their love spanned eighty-seven years. On the night of the total lunar eclipse, the time and space channel opens again. Will she return to her own future, or stay in the war-torn past? And Cheng Yiqing's words "No matter which time and space, I will find you", is it a vow or the beginning of another time and space paradox?
