On the night of the funeral, Shen Zhiyao received a death notice signed by himself among his father's belongings. The time of death was exactly midnight tonight. He was supposed to be the mourner, but instead he became the declared dead. Qiao Heming of the police's serious crime team was ordered to investigate this bizarre incident, but found that all the evidence pointed to Shen Zhiyao as the murderer who planned his death - but Shen Zhiyao insisted that someone was using his identity to plan a serial revenge. When the third corpse appeared, with the same code as Shen's father's last words embedded in its chest, Qiao Heming realized: the real hunter had long been hidden among the living, and both of them were chosen pawns.
