To save the company money on electricity, Zhou Qiaoyun secretly shut down the server room's cooling equipment, causing a multimillion-yuan contract renewal to fall through and inflicting enormous losses on the company. When she was held accountable, her brother, Zhou Mingkang, repeatedly concealed the truth and covered for her, ultimately driving his wife, Lu Zhiwei, into a desperate situation. When family ties are placed above the rules and trust is repeatedly abused, Lu Zhiwei chooses to expose the truth and hold those responsible accountable. More than three million yuan in losses and a marriage shattered beyond repair—everyone ends up paying the price.
