Uniformes et Grandes Manoeuvres plot
Ruined but sympathetic, André Duroc obtains from Luc, an endearing flier with no money and porter of the nightclub "Miramar", that he may pass as a duke with the intention of stealing the money from his aunt Solange Duroc. On the domain of Cigalière, where the latter lives, André introduces his mistress Yvonne as Luc's sister. But things get complicated when the beautiful chambermaid Alice falls in love with Luc, while André breaks up with his mistress Yvonne to win the heart of the sweet Marie-Therese. One day Luc has to run away and because he wears the uniform of a paratrooper, he has to participate in big maneuvers, something for which he is totally unprepared.
