Synopsis
1948. Clément Mathieu, an unemployed music teacher, finds a job in a correctional boarding school for minors. Stunned by the harsh reality of the school’s routine, particularly the extreme, largely ineffectual policies of the school’s director Rachin, Mathieu sets out to change the pupils’ lives by acquainting them with the magic and power of music. Among the students there is a rebellious and wild boy who has an angelic voice. Thanks to his natural talent, with the help of Clément - who is fascinated by the boy’s voice and has fallen in love with the student’s mother - the boy will change his life’s direction.
