The Virtuous Sin was adapted from The General, a novel by Lajos Zilahy. Kay Francis plays Marya, the wife of overly sensitive scientist Sabin (Kenneth MacKenna). Commissioned into the Russian army during WWI, Sabin can't cope with the rigors of military life, and as a result is condemned to death for insubordination. To save his life, Marya offers herself to libidinous General Platoff (Walter Huston), even willing to rendezvous with the general in a seamy bordello. Against both their better judgements, Marya and Platoff fall in love, whereupon the far-from-grateful Sabin threatens to kill his rival. The Virtuous Sin may have a silly storyline, but otherwise the film does a remarkable job re-creating the milieu, manners, and costumes of 1914.
