Karaoke.

Bénédicte, a famous opera singer, leads the life of a diva between Parisian palaces and social gatherings. After an evening of excess, she sees her career crumble. Fatou, also a palace regular but as a cleaning lady, is the only one to reach out to her. Passionate about singing, Fatou has one idea in mind: to convince Bénédicte to take part in the big national karaoke contest. The perfect vocal mastery of one and the tenacity of the other could well create sparks and take them very far.
