Doctor Gesellius travels to China to research the effects of opium. There, he frees a young woman named Sin from a mafia led by Nun Chiang, who swears vengeance. On the way back to his home, Gesellius discovers that Sin is the illegitimate daughter of one of his colleagues, whose son is having an affair with the doctor’s wife. After the revealing discovery, his colleague’s son turns up poisoned, making Gesellius the prime suspect.
