 Aging opera singer Joachim Dallayrac retires from the stage and retreats to the countryside to school two young singers, Sophie and Jean. Although the rigorous training takes its toll on both teacher and students, there is plenty of time for relationships to develop between the three. Based on their teacher s reputation, Sophie and Jean are invited to participate in a singing contest staged by Prince Scotti. Scotti s protege is set up to get revenge for Scotti s defeat at the hands of Dallayrac in a similar competition many years ago. The young students overcome Scotti s trickery to win the competition.
