Dédé is a young wealthy man who buys a shoe store, owned by his friend Robert, in order to receive more conveniently his mistress. Everything seems fine and Dédé seems to be enjoying all of this. But the man barely knew that he would fall in love with one of the many pretty vendors of his new "acquisition", favoring this new girl over the previous one.

Composer Joseph Lanner is jealous when the first violinist in his orchestra, none other than Johann Strauss, wants to form his own orchestra also in Vienna and write his own compositions.

Célestin, the organist of a convent, has written and composed a light operetta under the name of Floridor. One day, the Mother Superior asks him to chaperone one of the boarders, Denise de Flavigny, who is returning home to get married. Now, Denise, for all her goody goody looks, soon proves as saucy as can be. Things get even more complicated when Célestin starts courting Corinne, the star of his operetta, to the great displeasure of a commander of dragons, the young woman's lover. Worse, the latter is none other than the Mother Superior's brother... To say nothing of Lieutenant Fernand de Champlatreux, who happens to fall in love with Denise, his fiancée that he has never seen before...!
