Man Jiang Hong plot
During the Shaoxing period of the Southern Song dynasty, four years after the death of hero Yue Fei, Qin Hui leads his troops to negotiate with the Jin kingdom. On the eve of the meeting, the envoy of the kingdom of Jin dies in the prime minister's residence and the secret letter he was carrying disappears. Coincidentally, a petty soldier and the deputy commander of the personal battalion are involved in this conspiracy. Premier Qin Hui orders the two to find the killer within an hour, but things are far from easy. With the investigation fraught with danger, the truth behind the case seems to be hiding a bigger conspiracy.
