Ten years ago, Xie Zheng took the blame for his half-brother Tang Huaichuan and went to prison. Ten years later, just after his release, three people connected to the old case were murdered one after another, and each crime scene bore traces unique to Xie Zheng. Detective Su Yanhuai was ordered to hunt him down, while forensic pathologist Ning Wei discovered in the autopsy details that the killer had access to the police's most closely guarded secrets. An old friend, Shao Jiu, brought him a list of missing people, while Tang Huaichuan rushed to clear his brother's name. Xie Zheng must find the real killer while the entire city hunts him, or he will go from scapegoat to a serial killer everyone believes him to be.
