Zhou Jianguo has run a building materials store for two years, and has been owed 86,500 by his brother-in-law Liu Hao on credit for a long time without repayment. As Liu Hao prepares to decorate his marital home for his upcoming wedding, his wife and mother-in-law blindly favor the younger brother, forcing Zhou Jianguo to provide free decoration materials and applying layers of pressure using family affection and face. Time after time of bottomless support and endless emotional kidnapping makes Zhou Jianguo see clearly at last: a soft heart and family devotion can never in the end trade for the understanding and boundaries of family members.
