Shen Meng Jun is a crotchety prideful 70-year-old widow who frequently finds fault with everyone around her. She takes pride in her ability to raise her son single-handedly, despite the poverty during the Cultural Revolution, to become a professor of a prestigious university. She shows her bias towards her grandson Xiang Qian Jin because he aspires to become a musician and he represents a dream that Meng Jun cannot achieve herself. However, she had no opportunity to be a singer. Although kind to her grandson, she is very critical towards both her daughter-in-law, Yang Qin, and granddaughter, Xin Ran, who openly treats Meng Jun with contempt for the way she treats her mother. This leads to Yang Qin fainting due to the pressure placed on her. After this incident, the family decides it's time for her to go to a nursing home. Feeling forlorn, she wanders the streets and impulsively decides to take a final portrait at a photo studio she happens by. Upon leaving, to her astonishment she realizes that she has been transformed back into her 20-year-old self. Given a magical second chance at youth, she changes her name to Meng Li Jun.
