Lost in the middle of the countryside at the wheel of her old Kangoo, Siham is desperate to find that "bloody party". In the back seat, Marguerite and Arthur, aged 15 and 8 respectively, are determined to put her through hell. In this rolling crisis cell, tension builds to a crescendo. Elsewhere, in a gymnasium transformed into a meeting room, a mysterious gathering is taking place.
Set in the shrine of French dance, the Garnier Opera house, L'Opera follows three characters whose dreams clash with reality, whose ambitions collide with expectations, and whose purity faces corruption.
