Fruitless effort to save the girl out of misery, this is the proof of my existence.
Belonging to nowhere, Jung-cheol lives alone in a deep mountain like a non-existent being. One day, he hears a song that Ji-soo sings in a town square. Attracted by her voice, Jung-cheol follows behind her, and observes her everyday life, and learns how she has been. When Jung-cheol tries to help her out of the situation, Ji-soo suddenly disappears with Jung-cheol’s money. Desparate Jung-cheol looks for her everywhere only to find that now she belongs to somewhere that Jung-cheol can’t take her out; a brothel.
