Someone from their classmates is poisoning the girl day by day. At first, Lu Xu cannot believe that the danger comes from someone in their group. However, gradually she realizes: among the future doctors hides a ruthless criminal. He is smart, patient, and cautious, and no one believes her words. The search for the truth stretches over years. The deeper Lu Xu delves into the circumstances of the crime, the more frightening details she learns.
