A boy finds himself trapped in an empty space and tries, in vain, to communicate with the world around him. But his only form of communication is his flute, that seems to be unheard by anyone. Life passes through him in the midst of sadness and loneliness, where the empty space mirrors the feelings of a confused and angry being for not understanding the reason why he lost his freedom to live.
