Thirty years ago, Andrei Simoniovich Filipov (Aleksei Guskov) was the celebrated conductor of the renowned Bolshoi Orchestra. But during the communist era, he was fired at the height of his fame. Demoted to the position of cleaner at the Bolshoi, he learns by chance that the Châtelet Theatre in Paris has invited the Orchestra to perform. In a moment of inspiration, Andrei intercepts the invitation and reunites his orchestra to perform in the place of the current Bolshoi Orchestra. He wants Anne-Marie Jacquet (Mélanie Laurent), a young virtuoso with a mysterious past, as the solo violinist to accompany his old Jewish and gypsy musicians. As the night of the performance approaches, tensions rise as the stakes grow higher. If Andrei succeeds in pulling of this grand deception, it will be the greatest triumph of his career.
