The tragi-comic chronicle of a passionate friendship between Boris Lassef, brilliant but insufferable and tyrannical actor and director, and Léon Yvrard, his confidant and all-round man in love with him, indispensable slave and clever schemer. This terrifying duo, which operates in the theatrical world but can be found in all spheres of jet-society, is about to be shattered by Léon's sister-in-law Nadège, a small but formidable teenager who, thanks to her malice and devastating determination, will succeed in triumphing over Léon and marrying the illustrious Boris.
