In this animated feature, a swan named Louie (Dee Baker) breaks out of his egg to an enthusiastic reception from his proud parents. Soon, however, it is revealed that poor Louie cannot make a sound, alienating him from his siblings -- trumpeter swans who have lovely calls. Louie grows up mute and falls in love with Serena (Reese Witherspoon), but struggles to find a way to communicate his feelings for her. It is not until Louie masters the trumpet that his love finds free expression.
