Mara moves to Italy with the dream of becoming a great cellist. At the music school in Milan there is great competition between talented students and she chooses the most difficult course, directed by a sadistic and ruthless teacher but whom she greatly admires. She thus joins a string quartet but the pupil-teacher relationship is destructive. Trampled and scarred, she leaves the school and decides to isolate herself, tending to her own stubborn aspiration, practicing exhaustively to prove to herself the talent denied her. She thus begins to live with inhuman rationality by eliminating everything superfluous, giving up and choosing to live with only 100 objects. A slow and inexorable self-destruction. Mara, however, will find in this experience the balance to capture with music the ephemeral moments of beauty, enclosed in a revolutionary and ingenious composition.
