Giovanna Avena

Gabriella, a maid, wears a jewel at a dancing party which belongs to her mistress, and when it is stolen she is accused of the theft and sent to jail. Some other maids organize a search party for the real thief who seems to be a moustached youth who continually sings a popular song.

A great Party is given by the rich family of Improta. Every kind of intrigue gets around this party. The purpose of every plan is to find a husband or a wife with a quality: wealth.
