Chiaki is requested as the regular conductor for the Roux-Marlet orchestra in Paris. His master Stresemann himself was once the musical director and conductor for this traditional orchestra, but as things turned out, it´s not in a good shape anymore. After seeing their bad performance, Chiaki sneeks into an audition as a regular violinist and discovers that a lot of the members quit, while the rest of the ensemble is in bad mood. When their present conductor suddenly quits a few days before a performance, Chiaki has to stand in, before his job as their regular conductor even begins officially.
Meanwhile, Chiakis feelings for Nodame get stronger as their relationship gets more intense. Though, the visit of Rui, a beautiful female violinist and acquaintance of Chiaki, brings more trouble for them.
