Giulio needs to spend more time with his children and, in agreement with Cesare, hires a maid, Daniela. The woman, however, falls in love with him and the innkeeper must try in every way to resist the young woman's assaults. Meanwhile, Alice, to impress a boy, joins the school soccer team coached by Cesare and Lucia returns from America.

Little Mimmo is in love with his classmate Sara, who plays the princess in the school play. The child, in order to be close to her, accepts the part of the maid of honor and asks Lucia for help in getting ready.
