Our story opens with a scene on Fifth Avenue, New York, in the neighborhood of 34th Street, where a small crowd is gathered about Papita, a little street singer, who stands holding her father’s hand, singing to the assembled men and boys. Suddenly Papita’s father falls and upon the arrival of the ambulance it is discovered that he has died from heart failure. Carl, a young musician, who has been attracted by Papita’s singing, observes the plight of the little street singer, and takes her to his home, where the exquisite quality of her voice impresses both Carl and his mother. Ten years pass by and the voice of the little street singer continues to improve. Carl finally decides to take her to a great vocal teacher. After a few months under the instruction of the master, Papita makes her appearance in the drawing-room of a rich patron of music. The wonderful promise of the fair singer impresses them all and Mrs. Burleigh, a lady of means, offers to give Papita a musical education abroad. Papita leaves for Europe and after three years of hard study under the leading teachers, she returns to America and makes her debut at the Metropolitan Opera House. Carl visits the opera and sends his card in to Papita. The card is intercepted by Mrs. Burleigh, who meets him and informs him that Papita does not wish to be bothered. Carl becomes ill, brooding over Papita’s apparent ingratitude. Papita, after scoring an immense success at her debut, feels there is something lacking to complete her happiness and, alone, she goes in search of Carl and his mother. Arriving at the former home of Carl, she learns that his mother died some time ago and the neighbors have no knowledge of the son. While walking through the street she hears the sound of a violin and readily recognizes that it is Carl playing her favorite air. Entering the house she climbs the stairs, locates the unhappy musician and proves to him that her heart is true.
