The cold-faced forensic doctor Li Jin read the silent testimony of serial murders from the lines on the bones with blood on his fingertips, while the genius police detective Jiang Jueming always left unexplained old things next to the corpses. When the seventh corpse has the same marks on its chest as those of an unsolved case ten years ago, the two are forced to join forces - one is the death translator who uses a scalpel to cut open the darkness of human nature, and the other is a madman hunter who relies on intuition to tear apart lies. They share the same secret key: the truth is never in the testimony, but in the silent breathing of the corpse.
