Forensic doctor Ji Han, who had been silent for ten years, recognized his biological son's fingerprints in an autopsy report. The cold autopsy data actually pointed to a deliberately concealed human experiment. Shen Zhao, the criminal police captain who worked alongside him, hid key files. Vice-president Lin Yanqiu actually robbed people in the name of saving people, while Zhou Ling, the silent assistant beside him, turned out to be a living witness of this tragedy. When the corpse begins to speak, the silent one must choose - continue to bury the truth, or use flesh and blood to tear apart the shady curtain of the entire system.
