Ténor plot
Antoine is a young man from a Parisian suburb. He studies accounting without much conviction and divides his time between the rap battles he practices with talent and his job as a sushi delivery man. During a visit to the Garnier Opera, he crosses paths with Mrs. Loyseau, a singing teacher in this venerable institution, who discovers in Antoine a talent that has yet to be developed. Despite his lack of opera culture, Antoine is fascinated by this form of expression and is persuaded to follow the lessons of Mrs. Loyseau. Antoine has no choice but to lie to his family, his friends and the whole city, for whom opera is something bourgeois, far from their world.
