It tells the story of Lu Li who, in order to find a part-time job during the summer vacation of his freshman year, was put in a sack by a trafficker on the street and carried into a car and sold to Xu Yihang, the boss of Bao Gong. The trafficker drugged Lu Li. Under the influence of the drug, Lu Li had sex with Xu Yihang in the work shed. Xu Yihang also lied to his mother Zhang Hui that she was introduced by a friend and gave her an introduction fee of 5,000 yuan. A month later, Xu Yihang took Lu Li back to Xu's house. Lu Li finally told Zhang Hui and Xu Yihang in the kitchen. He spent 5,000 yuan to buy her and left the Xu family villa. He called his parents downstairs in the Xu family villa and asked them to call the police. However, at this time, Lu Li found out that she was pregnant.
