The story begins in the late Qing Dynasty and early Republic of China. It tells about a sensational homicide and robbery in a small town in Hubei.

The case was unfolded in an unexpected direction at this time, and things were not as simple as Deng Taki and others had imagined. It turned out that it all started with a wrongly judged case ten years ago...
