Retired teacher Shen Jing goes to a high-end apartment to work as a private tutor to supplement her household income, only to abruptly see a family portrait of Lin Jianguo, her husband of thirty years who shares her bed, hanging on the wall of her student Lin Xiaoxiao's home. The female homeowner Li Qin wears the jade bracelet, a "missing" heirloom left behind by Shen Jing's late mother. Amidst a dispute over an 80,000-yuan shattered vase and a police report demanding compensation, Lin Jianguo, walking in with a cake, catches this scene on the spot, even falsely claiming to his wedded wife that she is a "distant relative who went to the wrong door" in order to protect himself. Facing thirty years of deceit and betrayal, Shen Jing casts aside hysterical crying and wailing, and calmly and decisively initiates a desperate counterattack.
