Liang Zhicheng brings his mother to the city for a follow-up medical examination, but his wife, Xu Yan, refuses to let her stay even for one night. Her younger brother has been living in their home rent-free for three years and even wants to use their apartment as his marital home. While her husband is taking his mother back to their hometown, Xu Yan actually dismantles the couple's bed. Liang Zhicheng finally stops giving in. He takes back the keys, settles the accounts, and demands that his brother-in-law move out and repay the money as agreed. Xu Yan returns to her parents' home, only to discover that she cannot even borrow her younger brother's bed. Only then does she understand her husband's grievances. But although the bed is eventually moved back, their marriage cannot be restored. The two ultimately divorce, and his mother can finally stay peacefully in her son's home.
