The Zurich Opera House is one of the most renowned in Europe. Fifteen premieres are staged here every year - a significant achievement, when one considers just how much work goes into each individual production. In this exciting documentary, we go behind-the-scenes at the Zurich Opera House and follow the intensive progress of the new production of Gioachino Rossini's Il Barbiere di Siviglia with Vesselina Kasarova in the role of Rosina. The film also shows preparations for other productions, such as a workshop for Richard Wagner's Siegfried directed by Robert Wilson, and a rehearsal for Igor Stravinsky's Le Sacre du Printemps with choreography by Heinz Spoerli. This film opens the curtain to understanding an opera house’s many exciting facets.
