Shen Qingci, the forensic doctor of the Municipal Bureau, recently encountered a troublesome "coincidence". The scar characteristics of each abnormally dead corpse she dissects will be accurately reproduced around her in a fatal manner in the following day - special diatoms in the lungs of the drowned are quietly mixed into her coffee; compounds precipitated from the burn marks fill the air with the same smell in her car. This is not an accident, but a highly intelligent killer who knows everything about her and is tailoring a cruel art exhibition called "Death Preview" for her. When the notice on the seventh day pointed to her becoming the final "perfect work" on the autopsy table, Shen Qingci knew that passive avoidance was over. She must use her only weapon - the forensic eyes that can read the truth from every tiny scar, reversely dissect the murderer's habits, psychology and past, and personally send this hidden "artist mentor" to the trial before the countdown reaches zero.
