While Augusto, out of the hospital, starts a relationship with Gabriella, Eva returns from Milan with her friend Beatrice. Giulio, hoping that Marco will fall in love with her and forget his stepsister, convinces his son to organize a party. Marco, however, disappoints his father's expectations. Meanwhile, Lucia, due to the return of Professor Zuppante, has to leave school.

Alice hangs out with a bully named Riccardo who, in order to be accepted by Giulio, tries to appear serious and studious. When the innkeeper, with Rudi's help, discovers the boy's true nature, he reserves his most classic punishment for him: the broom. Meanwhile, Marco, while still being troubled by his feelings for Eva, lets himself be seduced by Rachele, the new teacher.

Rudi is growing up and seems to be morbidly attracted to girls. So Giulio, not without embarrassment, begins to address the topic of sex with his children. Rudi, however, wants to move from theory to practice and invites his friends home to play the "postman game". When the innkeeper catches Rudi kissing Alice, he goes back to his old ways. Meanwhile, Eva becomes jealous once she discovers the relationship.

After a strange phone call, Giulio becomes convinced that Lucia is being pursued by a man. After entrusting his children to the care of Ezio and Stefania, the innkeeper leaves for the United States with Cesare and Gabriella, but during the flight the Cesaroni brothers are mistaken for two attackers and repatriated. Upon his return to Italy, Giulio discovers that the mysterious John is none other than Lucia's gay roommate.

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.

At school Rudi and Alice compete for the role of gang leader, while Lucia, depressed by her absence from teaching, devotes herself with obsessive attention to household chores, worrying Giulio. Marco, abandoned by Rachele, confesses to Eva that months before he had been in love with her.

While Eva tries to win over Marco, who is distressed by the end of his relationship with Rachele, Giulio and Cesare find themselves in trouble with the tax authorities. With financial help from Gabriella, the two must accept the woman, Lucia and Stefania as assistants in the management of the wine shop. The business starts up again with flying colors, but the men are not happy with the female presence.

Lucia plans a group vacation at a campsite in Sardinia, but friends and relatives have other plans and one by one they back out, so Giulio and Lucia are forced to leave alone. Eva, convinced by Giulio to forget Marco, for the good of the family, follows Veronica to Croatia, while Marco and Walter leave for Greece.
