After the death of his mother, Isamu vows to give his siblings a better life. Isamu befriends Li Hua, a former member of the Green Gang, and begins his infiltration of the opium trade in Manchuria. After some obstacles and hardships, Isamu's morals change for the worse. His opium causes an increase in addiction and death, which Isamu claims is a necessary cost for a better life.
