After serving a prison sentence for no fault of her own, café violinist Helene seeks out her twin sister Betty, a famous revue star in Vienna engaged to a public prosecutor. During a sailing trip, the two sisters drown. Helene, at first involuntarily, then consciously, slips into the skin of her opposite counterpart. After a blackmail story, a happy ending ensues.
