The National Ballet of Portugal is celebrating its 40th anniversary. Since its foundation, it has aimed to present the great classics, as well as to always welcome contemporary creations. Day-to-day life is demanding for dancers, choreographers, musicians, répétiteurs, seamstresses, light technicians, sound technicians, and other elements of a large staff that make it possible for dance to travel through the rehearsal rooms and linger in the hallways before making it onto the stage. This film follows not only the company’s creations and premieres, but mainly each dancer’s silent and structural work.
