A girl makes a wish upon a star at a young age. The wish travels to the star and then back again to be fulfilled when the girl is older. The title symbolizes the passage of time (a single day) for the star and the idea of hope for the girl that something will happen one day. The plot is tightly choreographed and synchronized with the music and there is no narration. The story unfolds across three locations and from the perspective of three characters: The Star, the Girl and the Wish.
