A well-disguised disappearance, an abandoned factory that had been in dust for seven years.
Technician Chen Mo disappeared mysteriously, and the police files were clean and traceless. Everyone thought it was just an ordinary evaporation.
Only detective Zhao Gang knew that this was not a disappearance, but a silence.
All clues point to an ordinary person with a gentle appearance and no flaws - Lin Shen.
He doesn't smear blood or leave any traces, and all dangers become "accidents" in front of him.
The police found no intersection, no clues at the scene, and the logic was completely closed.
As the investigation deepened, the case of corpse dumping in the old factory seven years ago came to light.
A covered chain of interests, a knife hidden in the dark, a secret that must be kept tight.
