Jiang Michuan is the most silent trace inspector in the city bureau and the only "murderer" in the series of murders that night. Monitoring power was cut off, evidence was tampered with, and witnesses collectively lost their memory. The whole city recognized him as the only one to take the blame. No one knew that the blood-stained note in his pocket was written with the name of Gu Zhiyao - the former forensic doctor who had disappeared for three years and was his only light. When the autopsy report was secretly destroyed and the police badge was stepped into the mud in the interrogation room, Jiang Jianchuan realized: this purge was originally aimed at the truth left by Gu Zhiyao. He's not the scapegoat, he's the only one who remembers her.
