Fourteen years ago, Su Jianye embezzled the compensation paid after Su Qing's parents died in a car accident, along with their property. Su Qing grew up relying entirely on the support of her third uncle. Years later, Su Qing becomes a powerful business tycoon and acquires HDJ Group. Disguising herself as a cleaning lady, she infiltrates the company to secretly gather evidence that her uncle is abusing his position to frame her third uncle. Working with her trusted aide, she carefully puts her plan into action, breaks through her opponent's layers of security, and obtains the complete account books and witness testimonies. At an all-staff meeting, Su Qing reveals her identity as the company's president and presents all the evidence of Su Jianye's crimes. After the court proceedings, Su Jianye is sentenced to prison, and all the misappropriated inheritance is recovered. Su Qing protects her third uncle and reforms the company, finally clearing the injustice that had remained unresolved for fourteen years.
