At the age of sixty, Lin Jingqiu is diagnosed with terminal cancer. Intending to tell her family during the Mid-Autumn Festival, she instead encounters her husband, Gu Zhengshan, fighting to have her share a double plot with his first love, He Jinyi, and forcing her to divorce, while her children treat her merely as a tool to take care of the household. She cancels the cemetery plot and leaves home for treatment, rebuilding her life accompanied by her good friend Zhang Guifang. Eventually, her condition stabilizes, and she settles down between the mountains and the sea, completely breaking free from her indifferent marriage and family. Years later, Gu Zhengshan and the children fall into their respective predicaments, but Lin Jingqiu no longer looks back.
