Les voleurs de gloire (1926)

What would Paul Barkany be without the talent of his wife Véra, an opera singer? Nothing! But, although he is beholden to her, he reaps the benefits of glory alone. When he is seduced by a rival of his wife, Paul proves unable to write music anymore. Now ruined, he cynically appropriates the score of a young composer, in love with Véra. Véra remains silent and the opera is a triumph. But Paul finally breaks down, struck down by shame and remorse. Véra and the young composer forgive the repentant wretch.
