In childhood Cecile and Felix were playmates. Felix was gifted as a violinist and Cecile was fond of dancing. When Cecile's mother died her rich uncle, a domineering Frenchman, adopted her. Felix wandered the country over as a vagrant musician, until after ten years he secures employment as violinist in the orchestra at the opera house in the city where Cecile dwells. Wandering one evening Felix leans over a garden wall to behold a young girl dancing on the green. Having his violin under his arm Felix begins playing a measure, attracts the girl's attention and in the end they recognize each other as childhood sweethearts. The crabbed old uncle comes in search of the girl, and upon discovering the unconventional conduct of the young folks, strikes the girl with his cane and orders Felix from his grounds. Cecile rebels and leaves the grounds with Felix to begin living with him without the formality of marriage. There are weeks of happiness for Felix and Cecile, until the uncle demands of the police that they arrest Felix for unlawful practices and restore the girl to her guardian. At the opera house Cecile has met the director of the orchestra, who compliments her upon her dancing and flatters her vanity by declaring she should go to Paris as a premier dancer in the opera. When Felix is thrown into jail the uncle takes Cecile home with him. The girl takes advantage of an opportunity, and goes to Lecoq, the orchestra director, and begs him to take her to Paris. Lecoq has that day had an offer to become director at the Paris Grand Opera, and the girl conceives the idea of helping Felix from his predicament by effacing herself from the situation. To Paris she goes with Lecoq and the officials liberate Felix. With heavy heart the musician buries his grief in composing an opera. When the score is completed he sends his manager to Paris with the work. Lecoq is interviewed and discredits the value of the composition, but says he will present it to the management. Months pass and Felix hears nothing from his opera. He goes to Paris for the purpose of investigating. That day Felix arrives at the Paris Opera House. Lecoq is hailed as the author of a new opera. The premier of the ballot is advertised as Mlle. Genze. Felix goes that evening to the opera, discovers that Lecoq has stolen his composition, and also sees in Mlle. Genze the Cecile who deserted him and thereafter left him uninformed. Forcing his way to Mlle. Genze's dressing room, he finds her prostrated from an injury to her ankle that will keep her forever from dancing. Denouncing the girl Felix forces Lecoq to publicity admit his plagiarism. He then retires to seclusion crowned with the laurels of genius. Cecile languishes with a broken heart. Her physician learns her story, prevails upon her uncle to take her once more into his home, and when the girl still shows no sign of recovery, the uncle goes to Felix and tells him that Cecile lingers at death's door because of a broken heart. Felix forgets everything but his love for Cecile, goes to her and there is a blissful reunion.
