A painter lives with his patron (soon to be lover) in her fairytale-like Château. But it's 1914, and duty calls. Jacques becomes a hero, and gets married with another girl ,Louise Liègeois; his former mistress is not prepared to accept it and interferes in the couple's life, demanding a portrait of her as a Valkyrie.

Italian-language version of the Germany-made DER TEUFELSBRUDER (FRA DIAVOLO), with different supporting cast and some scenes. Based on the Auber opera, but with generally original music by Dr. Giuseppe Becce.
