Chen Mo is a young criminal police officer who has just been transferred to the Municipal Bureau's Criminal Investigation Team. The first bizarre case he took on was spine-chilling - after the deceased was cremated, the family actually received a call from his cell phone. The recording whispered: "Don't burn me... I'm still alive."
Three identical cases occurred one after another. The deceased had their bodies processed by the same funeral company. Technically unexplainable phone calls and figures in white coats in the cremation room late at night meant that the truth was covered up.
He accidentally obtained a golden finger that can analyze the residue of abnormal brain waves. He can capture the fragments of the deceased's dying consciousness from the scene and restore the erased memory traces.
This ability allowed him to see details invisible to ordinary people: the phone calls were made unconsciously by the pseudo-dead, and they were briefly "alive" and sent to the cremator.
While others were still checking surveillance and confessions, he had already locked into the criminal chain through the afterimages of his consciousness and pointed directly at the illegal low-temperature resuscitation experiment.
As a series of strange and unsolved cases were uncovered, the shady story of the funeral home, the missing 13th floor, the personality replacement in the plastic surgery hospital, and the city-level hypnosis experiment came to light.
He is no longer an ordinary detective, but the only one who can hear the "echo of death". He walks on the edge of science and the unknown, tearing apart a consciousness control plan that has lasted for decades.
In the end, he will face the ultimate question - who is he?
