Twelve years ago, a series of major cases occurred in Jinyang City. The victims were all women around ten years old, wearing ballet shoes and with abnormal bruises on their necks. Among them were the twin daughters of Huang Zhenyao, the then criminal police captain. Under public opinion and under pressure, the Jinyang Criminal Police Team quickly arrested the murderer. The criminal personally admitted to committing the heinous crime. The evidence was conclusive but he was only sentenced to life imprisonment. At the same time, the murderer remained silent about the motive and weapon.
Twelve years later, the case happened again. The victim was a young woman in her twenties. She was also found wearing ballet shoes and had an abnormal neck. The detective captain at this time was He Fangyuan, known as the "Jinyang Criminal Police Artist." He personally participated in the case twelve years ago and concluded that the murderer knew the old case well and even knew details that the police had never disclosed. The final judgment was that it was not a copycat crime, but that the murderer committed the crime again after many years. He never imagined that the suspect never admitted that the murderer was someone else. Who is the murderer in prison? Who is the murderer outside the prison? What details were ignored twelve years ago? Who will be frightened by the crisis twelve years later? How does a criminal police artist break the situation? In the end, the mud is cleared away and the truth is revealed. Who is the instigator of this tragedy that spans the long river of time?
