As described in a review in a film magazine,[3] Joan (Nazimova), member of a band of Apache thieves, resents the attention of Lupin (Tellegen), their leader. She leaves and goes to the café of Papa ChuChu (Harlan), where a bunch of aristocrats see her dancing. One of them, Paul Dubois (Miller), is attracted to her. Lupin, jealous, waits outside to take her back, but she remains in the café all night. The next morning she meets Paul and tells him she wants to become a lady; he fastidiously suggests things that will help her and she takes him seriously. Later he is impressed by her earnestness and becomes interested in her, and she falls in love with him. One day she sees him attentive to another woman and becomes so jealous that she returns to Lupin and tells him of a statue of the Madonna with a pearl necklace that Paul's mother is giving the church, and makes him promise to that he will get the pearls and kill Paul. She is to give the signal, but discovers that the girl is Paul's sister. It is too late to stop Lupin. For days she broods, and Lupin, who loves her blindly, takes back the pearls, but he is wounded by one of his followers. In the church Joan sees Paul and is overjoyed that he was only slightly injured. However, the sight of the wounded Lupin brings her to the realization that it is Lupin that she really loves.
