Cassie, an orphan who sings angelically in a small-town church, marries the organist, L. I. B. Bell, when he promises to obtain singing lessons for her. They go to San Francisco, where Cassie leaves Bell within the hour when she discovers his low nature. Answering an advertisement in the paper, Cassie gets a job singing in a mining town dance-hall. There she charms everyone with her voice, including Madoc Bill, who, having just won a large sum of money at faro, writes her a check for $10,000 and sends her abroad to study voice. Cassie soon becomes a successful diva, singing in the Grand Opera at Moscow, while Madoc Bill serves 4 years in jail for murder.
