Nikolas, a young boy, lives blissfully watching the world go by. Stars float over his head, butterflies float through a valley of blooming flowers and the sun and the moon chase each other through the sky. Every­thing is warm and sweet and familiar until the Moon chases the Sun into the horizon and Nikolas' world becomes cold and dark. He sets off to find the Sun and Moon and goes on an emotional journey, discovering warmth in unusual places and facing despair for the first time. His journey is guided by the music, Nikolai Rimsky-Karsakov's "The Kalendar Prince" which is the emotional anchor­point of the film and also the base inspiration for the pacing of the film.
