Retired forensic doctor Chen Yan was urgently recalled for an autopsy, and his name was clearly written on the autopsy report - the entire police team was speechless on the spot. Apprentice Lin Xiao led the team to investigate and found that the deceased were all related to the medical scandal that was covered up five years ago. Archivist Su Tang hid the truth, technician Zhou Ye used codes to reconstruct death, and undertaker Qin Wu believed in the relics. When Chen Yan's handwriting becomes the epitaph of the deceased, he must tear open the hell sealed by his own hands between forgetfulness and awakening.
