Classical symphonic music is everything for 17-year-old Zahia Ziouani and her twin sister, Fettouma. Nevertheless, living in underprivileged Parisian suburbs in 1995 with their Algerian background, they struggle arduously to approach their dreams of becoming an orchestra conductor and a cellist.
Driven by determination, passion and courage, and with the fierce support of their parents, they fight against discrimination and prejudice, going as far as creating their own orchestra, Divertimento. Directed by Marie-Castille Mention-Schaar (A Good Man, Heaven Will Wait) the film is inspired by the life of Zahia Ziouani, one of the few worldwide renowned female conductors.
