About the Poster: According to a fairly obscure movie website, the synopsis for this movie reads: "This French musical comedy is set in guess what European city? A couple playing brother-and-sister nonconformists, go out on the town for a night of cool jazz music and dancing (not with each other, of course!) In the course of the evening, the girl falls in love with an Austrian pianist . To keep her new beau financially solvent, the girl innocently takes a rather shady job at a Parisian bar. The pianist misunderstands, but her brother comes to his sister's rescue and reunites the lovers. The musical numbers are forgettable, but performed with flair by an energetic cast."
