Forensic pathologist Shen Zhao is accused online of murdering her father. The autopsy report insists he “committed suicide,” but she knows the tiny spots of bleeding on his body could never have been caused by self-harm. Former detective Jiang Jin quietly hands her sealed original data, while Lin Ya, a deaf-mute plastic surgeon, uses tattoos on corpses to point toward a black-market network called “Project Zero.” As online celebrity Zhou Yan manipulates public opinion and puts her on trial, she uses her father’s remains as bait to draw out organ trafficker Huo Chen. The truth is more gruesome than she ever imagined in her darkest moments.
