Stars d'un soir: Franck Leroy is a famous actor, adored by the public. But in the professional world as well as in his private life, he is known to be demanding, unbearable, even detestable. In a few days, he is performing in front of the entire Parisian audience with his new play and the theater is already sold out. However, a week before the premiere, tired of the moods of the star, his fellow actors abandon him. Worse, no actor in the country wants to work with him anymore.
