In July 2015, a serial murder case occurred in Gaoning City, Dongjiang Province. The murderer used strange techniques to kill three people in a row, but no trace of the crime was left at the scene. Strangely, the three corpses all had text tattoos of the same size, and the victim's manner of death and crime location were exactly the same as a murder case eleven years ago. The murderer's arrogant behavior caused quite a stir in Gaoning City.
After Dongjiang Province learned about it, it immediately dispatched a task force from the provincial department to Gaoning City to assist in handling the case. During the investigation, the truth about the murder case eleven years ago is being revealed bit by bit.
Public opinion has no intention of stopping. The murderer seems to be inviting the whole society to play a scripted killing game, and the script is the murder case. Netizens spontaneously made inferences based on the clues left by the murderer, and soon deduced the victim of the fourth case and the place where he was killed.
At this moment, one of the perpetrators in this case was arrested, and he provided the police with the time when the last case was committed. In this way, the time, place and victims have been gathered together, and it is only a matter of time before the murderer is arrested.
The police set up a dragnet at the fourth crime scene and prepared to arrest him. But unexpectedly, just as netizens predicted, the fourth case happened as scheduled...
The ending is consistent with the results of the nationwide investigation, and everyone is discussing intensely about their superb investigative skills. But what the masses don't know is that the murderer's real purpose is to attract the attention of the whole people and vindicate the massacre of the family. He took advantage of this nationwide investigation to launch an anti-corruption struggle with great disparity in power.
