A special task force was formed at the Qingyang Police Bureau to investigate a series of baffling cases in Qingyang City. Its five members each had their own unique skills, and through seamless teamwork they solved more than a dozen cases, large and small. Behind those cases lay tangled love and hate, as well as the helplessness of everyday life. The killers struck again and again, but the law is vast and none can escape it. One by one, the task force solved these perplexing cases and brought the criminals who had been at large to justice. Nan Fengxi, the top detective at the municipal bureau, had solved countless cases and could handle anything. Han Yi was a criminal investigation expert, every bit as capable as Nan Fengxi. He Yutong was a renowned forensic examiner at the municipal bureau. There was no evidence she couldn't find, and she always said, “The dead can speak.” Her capable assistant, Li Linlin, also provided invaluable help in solving the cases. Finally, there was Shen Yu, who excelled at sanda and boxing and could knock a criminal down with ease.
