Little heroine, a music school student, wanders through the backstreets of Warsaw's Old Town and discovers a world to which others have no access. It is a world of extraordinariness and beauty of sounds. And these are sounds that are the most important thing for the girl – the hubbub of children, the sounds of the street, the puffing of a tractor, the tuning of an organ, the sweeping of a broom and the sound of jets flying overhead.
