Many years ago, Andrei Simoniovich Filipov (Alekseï Guskov) was fired as conductor of the Bolshoi Orchestra for hiring Jewish musicians. Now a janitor, he learns that members of the orchestra have been invited to perform in Paris. Andrei gathers his former players and plans to substitute them for the current ones, and he hopes that a beautiful virtuoso (Dmitriy Nazarov) will accompany them.
