[Modern times and the sins of 1998 reunite in a heavy rain]
New policewoman Lin Wan investigates a series of disappearances and discovers that the fluorescent symbols appearing on the backs of all the deceased are actually the same as the markers used in the cloning experiment in her mother's laboratory twenty years ago. The mechanical heart of suspended forensic doctor Chen Mo hides the truth of 1998, while evidence spanning time and space is frozen underground in seven hospitals funded by philanthropist Shen Tianyou. When the missing people began to be "resurrected" to deliver encrypted corpse language, and when the scalpel cut out the clone of herself when she was five years old, Lin Wan was forced to face the darkest choice in the twisted corridor of time: destroy the fluorescent code that symbolizes human evolution, or become a living altar for the birth of a new species?
