After Japan surrendered, the Sanjiang region in Northeast China fell into a power vacuum. Fang Shirong, a high-ranking official of the Kuomintang, wanted to recruit gangs to form an army. He killed five civilians and put the blame on the bandit Zhang Xiaolin. Zhao Tiezhu, an underground member of the Communist Party of China, was ordered to investigate the truth. After discovering the alienation plot, he went to Xuelang Mountain to persuade Zhang Xiaolin, but failed, and instead contacted other gangs.
The four major gangs launched a bloody war to seize the arms left by the Japanese army. Zhang Xiaolin relied on his calculating and ruthless methods to annex the three gangs one after another by sending undercover agents, paying off money, and sneak attacks, etc., And became powerful. Fang Shirong sent "White Peony" Li Guizhen to the mountain to win over him in the name of a condolence performance, but Li Guizhen fell into an absurd relationship with Zhang Xiaolin in which she and Zhang Xiaolin used each other and calculated against each other.
