Kept in seclusion by her alcoholic father, Peter McCormack, Innocent knows nothing of life beyond her own house in Mukden, China. Following McCormack's death, Innocent is placed in the care of his close friend, John Wyndham. John promises to protect the girl, but when the two visit France, he resumes his gambling habit, while she, awestruck by the glitter and excitement of the Parisian social scene, soon becomes infatuated with Louis Doucet, the handsome but unscrupulous owner of a gambling establishment. Louis convinces Innocent to run away with him to the Riviera, but John finally locates them in Nice and shoots her lover. Having fallen in love with his ward, John returns to China, alone and heartbroken. He attempts suicide but recovers from his wound, whereupon Innocent, who now realizes her love for John, follows him to Mukden and agrees to marry him.
