Sinopsis
A gang leader infiltrates a wealthy household in disguise to probe an old crime: her parents were slain and her infant son stolen. Casting off the timid demeanor of the woman she impersonates, she subdues insolent servants, protects the young boy, and gradually wins her husband’s trust. As she maneuvers against the shadowy masterminds, she uncovers the truth of her family’s massacre five years ago and finds the boy is her long-lost birth son. She finally unmasks herself as the head of a secret lodge. The villains are brought to justice, and the three are reunited.
