The serial killer "Professor" reappears in the city, arranges the murder scene with artistic cruelty, and deliberately leaves behind secret clues pointing to forensic doctor Wen Yulu.
Cold torture police officer Qi Mo was ordered to investigate and was forced to partner with this airborne genius forensic doctor. The two have very different personalities: Qi Mo is resolute and decisive and believes in intuition; Wen Yulu is rational and restrained and obsessed with evidence.
As the case deepened, Qi Mo discovered that Wen Yulu had some connection with the murderer, and the media began to portray Wen Yulu as an accomplice. When trust collapses, a more terrifying truth emerges - the two of them are what the murderer really wants to kill.
An old case from twenty years ago had already tied their fate. Now, under the dual pressure of public opinion storm and internal investigation, they must uncover this deliberately buried past before the "Professor" completes his final work.
