Her dancers include Lucy, the soubrette, capricious and obstinate, Franca, who left her beloved boyfriend Carlo with bitterness and suffering, because he was too poor for her ambitions, who aspires to a comfortable and luxurious life and Vera, in love , reciprocated by Mario, the son of a rich and wealthy bourgeois.

She will then end up committing suicide shortly after the wedding by throwing herself out of a window, when her repellent husband introduces her to his newly hired technical director, who is none other than Carlo, who in the meantime has managed to make his talent appreciated and to patent one of his invention.

In the police station, where the girl is summoned together with Nino, accused of circumvention of minors, however the unexpected happens when Vera recognizes in the man, the guy who had given her a lift with the car and who had tried, in vain, to abuse her.

At that point Mario's father, bitterly opposed to his son's relationship with a dancer, realizes that Vera is a good and serious girl and accepts her by apologizing and withdrawing her complaint.

By now Margherita, alias Rita Buton, has become a famous and acclaimed soubrette; Nino secretly goes to the theater where she is performing a show and leaves an anonymous bouquet of flowers at the entrance to be given to the girl.
