Harmony Wells, a gifted violinist, moves to Paris to complete her musical education. Her money soon disappears, and she is forced to live in an inexpensive pension house, where she meets Dr. Peter Byrne, a promising American surgeon who has come to Paris to study. The doctor falls in love with Harmony and proposes, but although she returns his love, she refuses him, determined to pursue her career. One of Peter's patients, a crippled child named Jimmy, who is dangerously ill, asks Harmony to brighten his hours by playing for him. Realizing that the boy is about to die, Harmony seeks out his mother, a dancer who deserted him for the vaudeville stage, but the woman arrives at her son's bedside too late. Shortly before Harmony's debut, she visits Jimmy's grave, where she meets the grief-stricken mother, who advises her to "play for your own children as you played for my little boy." Rushing back to Peter, Harmony accepts his proposal of marriage.
