Olive must be disposed of, so that Mme. Forresti would not adopt her. That was the decision of both Drew Martin and Laura, the other protegee of Mme. Foresti. Drew concocts a scheme by which Olive is led to believe that her unknown mother has been discovered. He and Laura hire a woman, who leads a double life, one aspect is that of a poor woman, who lives in a cellar, and the other is that of a crooked hag, who conducts a fence for stolen goods. Olive, believing that this creature is really her mother, goes to live with her, and leaves Mme. Forresti’s palatial home. Vance and Mme. Forresti both protest, but Olive resolves to live with her mother, at any cost. The police trace stolen goods to this woman’s home, and raid the place just about the time that Olive has found some of the concealed loot. They place Olive under arrest, and she, almost fainting, happens to lean against the wall, which in some unknown manner gives way, and precipitates her into a passageway. The police turn around and can’t find her. They are amazed and go outside to search. Meanwhile, Olive manages to return through the secret panel, and is confronted by the old woman, who thinks Olive has betrayed her. She attempts to kill Olive, but a heart attack prevents her executing the deed. She dies, telling Olive of her deception, and Olive, hearing the police returning, escapes back to Vance, and tells him the news that the woman was not her mother.
