In a place called Hulu Town in the northeastern region, there are two mountains facing each other, Qingpan Mountain and Longmai Mountain. There are famous overlords in the mountains: Jiuniang, the leader of Longmai Village, and Brother Xing, the leader of the Qing Gang. The two families have been engaged in gunfights over the territory for many years. Since Zheng Jiumei took charge of the family and drew clear boundaries with Liu Xing, their peaceful life has become a little turbulent. . . . .
In 1931, after the Japanese launched a war of aggression against China, the Japanese army gradually approached Hulu Town. The two gangs were forced to join forces to fight against Japan, but were betrayed by traitors. Nine years later, they met again, at the Japanese military headquarters. What is even more surprising is that the identities of the two have become confusing.
