On the day of the car accident, Jiang Yan died. However, surveillance video captured him killing the driver Lu Zhao with his own hands. The police wanted a 'living murderer', but the body of the deceased mysteriously evaporated. When Jiang Yan woke up from a coma, he found that memory fragments that did not belong to him were implanted in his brain. The witness was a deaf-mute car repairman. The forensic doctor's girlfriend had tampered with the autopsy report. Even the little girl he saved had a tattoo of 'him'. He is not the murderer, but the 'him' in the surveillance room knows his hands better than he does. The truth is hidden in the ring of the dead, in the memory of the living, and in the eyes of the child who should have died.
