Diagnosed as an autistic child, Grzegorz lives in his own world, not being able to connect with others. When he is a teenager, it turns out that the cause of his isolation is not autism but a deep hearing impairment, underneath which a great musical talent has been hidden for years. Thanks to a hearing aid, Grzegorz starts to discover speech, sound and music, in which he falls in love. Grzegorz now desires to become a pianist, but no one, apart from his family, believes that he will ever make his dream come true.
