France, 1995. 17-year-olds Zahia and Fettouma Ziouani have been dreaming of becoming a conductor and a cellist since they were kids. Their wish is to make classical music accessible to all, and everywhere. But this is kind of an ambitious dream for suburban teenagers. One that can only become true with dedication, passion, courage…and a project: to create their own orchestra. Its name will be Divertimento.
