Bad financial conditions compel an aristocratic family to do strange work.
Director Claude André Lalande illustrates the theme of three songs in images. We see and hear in turn Roland Gerbeau "Himalaya", Jacqueline François "From Montmartre to the Latin Quarter" and Jean Marco "The Ghost of Aunt Anna". This mini musical is one of the ancestors of music videos.
Annie, the ward of Monsieur Joachim, a nightclub manager, has fallen in love with Philippe Lebon, a singer who could easily re-float her guardian's failing business. The trouble is that Joachim has already - and hurriedly - betrothed Annie to his business partner. To make matters worse the young lady suspects Philippe of being unfaithful. In order to thwart the wedding of Annie and his rival, Philippe hires two of his friends, the resourceful Beaudubec and Tracassin.
