Stefania has disappeared. Giulio finds himself alone to care for the twins while Laura and Paolo try everything they can to find her. Paolo, meanwhile, also swept up in Valeria's enthusiasm, decides to throw himself into the nursery adventure, though he first wants to discuss it with Laura, who, however, is too preoccupied with her sister's disappearance. Stefania, unable to stay away from the girls, sneaks home, but is caught by Giulio, who decides to put her to the test. Paolo, meanwhile, finds himself having to deal with Laura's constant professional successes, which, while helping the family budget, also exposes him to some worries.
