Xu Yanzhou spends 800,000 yuan renovating his future marital home, hoping to surprise his fiancée, Lin Zhixia. Unexpectedly, renovation foreman Zhou Yonggui forcibly moves in with his son and the son's family. They occupy the master bedroom, dismantle the study without permission, secretly replace building materials, and even turn the home into a show apartment to collect renovation deposits from prospective customers. To make matters worse, they destroy the wedding dress left behind by Zhixia's mother. Faced with the family's outrageous occupation, Xu Yanzhou gathers evidence, contacts the renovation company, and reports the matter to the police. He eventually exposes their scams and fraudulent accounts, makes the Zhou family pay for their actions, and reclaims the new home that rightfully belongs to him and Zhixia.
