In the early years of the Republic of China in Yongxin City, Old Master Li of the antique shop was mysteriously murdered, and dozens of boxes of cultural relics went missing. The newly appointed detective Ye Hanzhou teamed up with the deputy detective Luo Ting, with whom he shared an old grudge, to investigate the case. During this period, they crossed paths multiple times with stage play queen Du Qing before investigating together. Ye Hanzhou and the others discovered clues, but were targeted by a "bounty hunter." The three-member team used their wits and courage against multiple factions to protect the cultural relics and pushed the defense of the treasures to the limit.
