Song Anning, the chief medical examiner of the 21st century, accidentally traveled to the Republic of China and became the eldest daughter of the Song family in Shanghai whose family was in decline and whose engagement was broken off. In order to survive, she knocked on the door of the patrol room with a scalpel and became a well-known female forensic witness.
The "living corpse" bell ringer in the midnight clock tower, the "skinless" bride floating on the Huangpu River, the popular dancer who was "cursed" to death backstage at Paramount... Strange cases that seem to be caused by ghosts and gods are all human conspiracies under her scalpel.
She used science as a spear to expose the false prosperity of Shili Foreign Market, but she accidentally got involved in a life-and-death game with the mysterious "Gui Xuhui", and also attracted the attention of Fu Yunshen (pseudonym), the powerful "Young Marshal" whose identity is a mystery. Sometimes he is a frivolous president of the Chamber of Commerce, and sometimes he is a cold-hearted and iron-fisted warlord. He lends a helping hand to her in critical moments time and time again, but he seems to be using her to investigate deeper secrets.
When the scalpel confronts the game of power, and when scientific rationality encounters the abyss of human nature, how will they join hands to speak for the dead and fight for the rights of the living in this city that never sleeps?
