Μετά τον πόλεμο, η Βάιολετ Εβεργκάρντεν χρειάζεται δουλειά. Φοβισμένη και απαθής, γράφει επαγγελματικά επιστολές, για να κατανοήσει την ίδια και το παρελθόν της.

Scenery that we have never seen. Sounds that we have never heard. Scent that we have never smelled. Food that we have never tasted. And the surge of emotion that we have never experienced. This is the expedition of recollecting the pieces torn apart and sensation left alone. When we reach that place, what will we think? Howling, 40 degree angle. Raging, 50 degree angle. Shouting, 60 degree angle. A wilderness beyond the heavy sea. The furthest south, far from civilization. At the top of the Earth. We will find lights through the girls' eyes to live tomorrow.

Ένα μοναχικό 17χρονο ορφανό αγόρι, επαγγελματίας παίκτης σόγκι, αρχίζει να βγαίνει από το καβούκι του όταν τρεις αδελφές τον παίρνουν υπό την προστασία τους.

Wakana Sakai was involved in music, but gave it up one day. Konatsu Miyamoto loves singing and can't be torn from it. Sawa Okita would do anything for her closest friends. They laugh, they fight, they worry, they love... Through their very ordinary lives, little by little the girls learn to move forward. Sometimes they feel as if they can't go on alone, but as long as they have their friends, they believe they'll make it someday. Wakana, Konatsu, Sawa, and the music they make in their ensemble weave a tiny but dazzling story of the power of music.
