Real estate tycoon Zheng Tianxiong died mysteriously in his banquet hall. His body was in a strange kneeling posture, holding a broken red wine glass in his hand. During the investigation, criminal investigation team leader Lu Chen discovered that the pinhole on the back of the deceased's neck and the half-sheet of architectural drawings soaked in red wine in the study all pointed to the "New City Project" that was suddenly suspended twenty years ago.
