At midnight, the alarm center received a strange call.
The owner of the caller number died in the forensic center four hours ago.
Forensic doctor Shen Yanchu discovered from the corpse, call recordings and a series of conflicting identity traces that this was not a simple murder. Someone is rewriting the lives of victims in the system: their names, social relationships, consumption records, addresses, jobs, and even time of death can all be replaced, forged, and inherited.
The dead are still "living", but the living are gradually losing proof of their existence.
As an old disappearance case is reopened, Shen Yanchu and Detective Gu Yu step by step get closer to the truth: What is truly terrifying is not that the corpse speaks, but that a person is quietly erased from the database, address book and memory, and no one can prove that she ever lived.
If identities can be transferred, who is the deceased?
If the evidence itself is engineered, where does the truth lie?
