A film director (François Truffaut) tries to get his movie made while observing the real-life dramas in his actors’ lives. Fading icon Severine (Valentina Cortese) forgets her lines when she drinks, while her co-star, Alexandre (Jean-Pierre Aumont), is fixated on his lover’s imminent arrival. Meanwhile, insecure young star Alphonse (Jean-Pierre Léaud) has emotional outbursts, yet seems well-balanced compared to Julie (Jacqueline Bisset), a British actress recuperating from a nervous breakdown.
