On the advice of the doctor, who fears a new trauma, the Cesaronis indulge the amnesiac Francesco who believes himself to be Giulio. The man usurps the innkeeper's place at home, in the wine shop and also next to Lucia.

Cesare, to encourage little Mimmo to take swimming lessons, boasts of being a great swimmer, but in the pool he is forced to confess that he fears water more than his nephew, keeping away from it. Faced with Mimmo's difficulty during the race, Cesare, however, does not hesitate to dive in to accompany the child to the finish line. Lucia and Giulio, meanwhile, try to stay close to Eva and Marco, still suffering from the end of their relationship. While Marco prefers to stay alone, Eva, resumes her relationship with Alex.
