Zhang Lu (Xu Lu) makes every effort to rescue the injured female patient Min. Zhang Lu tried her best, but Xiao Min passed away because of heavy bleeding. Xiao Min's mother Du Li (played by Song Chunli) is heartbroken and blames Zhang Lu. She believes that Zhang Lu's negligence caused her daughter's departure. Behind Du Li stood a more threatening figure, Xiao Min's stepfather Quan Wu (played by Jiang Wu). As the chairman of Weiye Pharmaceutical Group, he is a man with hands and eyes in this city. It was unexpectedly discovered that Zhang Lu was the daughter of a colleague Zhang Wenwen who was injured by herself five years ago. Du Li wanted to avenge Zhang Lu in court, but was stopped by the cunning Quan Wu. He did this to cover up a secret five years ago.
