On the winter night of 2006, 40-year-old Lin Wanqiu huddled in the corner of Tongzi Building after being domestically abused. In despair, she dug out the blue diary she kept when she was 16 years old. She tremblingly wrote her regret: "Xiaowan, don't marry Zhao Jianguo..." At the same moment, in the woodshed in 1982, 16-year-old Lin Xiaowan saw this line of handwriting from the future. From fear to trust, the two used their diary as a bridge to start a dialogue across time and space. Lin Wanqiu used her half-life experience of blood and tears to guide Lin Xiaowan to avoid the trap of fate - to keep her studies, resist an arranged marriage, and become financially independent. And every brave choice made by Lin Xiaowan fed Lin Wanqiu's current situation like a butterfly effect: the frequency of domestic violence decreased, memories emerged, skills were unlocked, until the perpetrator "never existed." When Lin Xiaowan boarded the train bound for Shanghai and Lin Wanqiu stood up again in the new era, they finally discovered that the source of this 24-year redemption was actually the obsession of a dying old man who exhausted his life. This is a dialogue between three "I's" and the most thrilling reconciliation between a woman and her destiny.
