Forensic assistant Su Mian has a secret-she can "hear" the last memory of the deceased. This ability makes her a weapon for the police force to solve crimes, but it also allows her to repeatedly wander the boundary between death and reality. Until she dissected a female corpse, and the last face in the memory of the deceased was actually the criminal police captain Lu Zheng who sent the corpse. When she looked up, the man was smiling at her. From then on, every corpse spoke, and every clue pointed in the same direction - the living people around her. When all the dead point to an "impossible" truth, Su Mian must make a choice: Believe in the evidence or trust in people's hearts?
