Among the crowded streets around Paris's Chateau Rouge Metro station, a modern apartment block rises up incongruously. Here, virtuoso clarinettist Simon Eskenazy (Antoine de Caunes) is trying to finish his record. He is also resisting his sick mother's pleas to stay in his apartment, while coming to terms with the reappearance of ex-wife Rosalie (Elsa Zylberstein) and their ten-year-old son; then there are his musicians, his insistent agent, Arlette (Catherine Hiegel), and his current lover, Raphael (Micha Lescot). And then there is Naim (Mehdi Dehbi). By night he is Rose, waitress at the 'Paradise' cabaret. Fragile yet violent, loving, funny, elusive and provocative, he is the artist of his own life; in a heartbeat, he can transform himself into a femme fatale. Simon, an Ashkenazi Jew, and Naim, a Muslim, are worlds apart. But this film is both a love story and a dizzying comedy, in which Simon is forced to let go of all his preconceived ideas and fears.
