The story is based on real history, describing the events that happened on the Shanghai spy front after the Battle of Songhu.
The incident originated from a mysterious spy team that had been lurking within the enemy for a long time. They provided two pieces of heavyweight information during the Battle of Shanghai, which attracted the attention of the Juntong and the Japanese Special Higher Police.
In order to take control of this group, Dai Li sent Wang Xing, the stationmaster of the Shanghai Military Station, into the Special Higher Police and began the operation of ’replacing the peach’. Unexpectedly, Wang Xing was assassinated before he could establish a firm foothold. However, it was this assassination that made the mysterious spy team gradually surface.
What Wang Xing did not expect was that the order for this assassination mission came from the commander. And the one who carried out this assassination was precisely that mysterious spy team.
In order to avoid the investigation of the Special Higher Police, this mysterious team, under the leadership of Cheng Xiaofeng, a high-level spy, made up for the crisis brought by the operation time and time again.
