When forensic doctor Lin Wu dissected a female body in the river, he discovered that the deceased's fingerprints exactly matched those of the victims of the ballet's mass disappearance ten years ago. As the investigation deepens, she is forced to get involved in the treacherous world of Jiang Chen, the chief pharmacologist of a multinational pharmaceutical company - the darkroom of his study is filled with secret photos of her since she was a child, a clone with the same DNA as hers sleeps in the laboratory's culture chamber, and his right ring finger is soaked in a bottle of formalin in her office.
The intervention of folklorist Shen Qingwu makes the truth even more confusing: the "Twin Sacrifice" ritual recorded in ancient books overlaps with the details of the case, the mother's relics hide the experimental number, and in the abandoned theater on a rainy night, countless mirrors reflected corpses with the same appearance as hers.
When Lin Wu uncovered Jiang Chen's lies about tampering with his memory, he discovered that her medical records showed that she had been taking anti-rejection drugs for seven years; when she finally stood in front of the freezing cabin, "Lin Wu" who was sleeping in the cabin had a silver bell necklace exactly like hers hanging around her neck. The trial record of the disappearance case ten years ago was clearly signed in her current handwriting.
In this closed-loop scam that spanned ten years, the cruelest truth was that the living "Lin Wu" was just the last abandoned container, and the real abyss had already dragged her into an endless mirror reincarnation when she took over the platinum cufflinks engraved with "C&S".
