"Tu seras duchesse!" ("You'll Be a Duchess!") With these words, self-made industrialist Poisson orders his daughter Lucie to marry a wealthy Duke. The duke's father objects to the union, whereupon Poisson arranges another marriage for his daughter, this time to an impoverished and sickly young marquis. Poisson's strategy runs something like this: the Marquis is expected to die soon, whereupon the widowed Lucie will become a marquess, and thus a worthy bride for the Duke. But the Marquis foils these plans by staging a miraculous recovery. The explanation? The Marquis and Lucie have been in love all along, and this was the only way that they could wed with Poisson's blessing. Darned clever, these Frenchmen!.

Remember when Julie Andrews in The Sound of Music says "Every time God closes a door, He opens a window?" Well, this is basically the same philosophy followed by a sage authority named Professor Azais. Though he is never seen in the film, Azais's influences dictates every move made by Le Baron Wurtz (Max Dearly), a private tutor. Though he suffers quite a few setbacks, Wurtz presses on, armed by the Azaiz philosophy that every time something goes wrong in one part of the world, it is balanced by something going right elsewhere. This "law of compensations" pays off in big laughs for the audience, and in a happy-ever-after for Wurtz. Azais was based on a play by Georges Berr and Rene Verneuil.
