In the winter of 2025, the first bizarre case lurks in a pork shop in the southern district of Shanggu. Butcher Zhang Tu dies in a cold-storage room, his skull split open and his brain missing.

Former detective Song Xunxing pursues the killer as a private investigator, carrying half of a rubber-chain pendant and a notebook that spontaneously fills with unfamiliar writing. Haunted by a wrongful conviction, she still feels guilty over a corpse buried on campus three years ago. Now the writing in the notebook and gaps in her memory hint that another truth may lie beneath the world she knows.
