Our story is about Su Yuan, a surgeon in a hospital. She is very serious and responsible for her work. Her boyfriend, Li Wei, is her classmate, who is excellent in all aspects, but a little harsh, jealous and suspicious. Not long ago, Su Yuan just finished her first kidney transplant independently. But Su Yuan didn't know that the kidney she implanted in the patient came from an organization that illegally bought and sold organs. This organization is very strict, and some people use car washing to hide their eyes and ears. In fact, Liu Qiang and others, who are in charge of imprisoning donors, help patients who need kidney transplantation to contact illegal kidney sources, and act as the head nurse of an intermediary hospital, Tan Xia, and Lu and others who ostensibly work in a plastic surgery hospital in Licang and engage in anesthesia. In fact, this man is the second person in the whole criminal organization.
