Criminal police captain Lu Ming took over a massacre that overturned his twenty years of criminal investigation knowledge. Surveillance video showed a family of four getting up at the same time like puppets late at night and calmly strangling each other to death in the living room. The only thing they have in common is that they all came into contact with a folklorist who had been missing for seven years a week before their deaths.
When the evidence gradually pointed to the metaphysical taboo, and when the young policewoman screamed and pointed out the four black figures standing behind him, Lu Ming knew that the matter was far from over. He must race against time to uncover the truth behind the scholar's disappearance and the bloody mystery about "substitution" and "reincarnation" behind the yellowed ancient book before he is completely swallowed by the strange curse.
The rules have been twisted and the logic has completely failed. What he faced was no longer a vicious criminal, but the evil spirit itself that had been around for thousands of years.
