The Cesaronis return to Garbatella, more relaxed than ever. Giulio runs the wine shop with Augusto, unaware of what's about to befall him. Marco is about to say his wedding vows to Virginia, with whom he has Adriano. Mimmo makes his debut as a special education teacher at school: Stefania is the principal, while Rudi works as a janitor in the hallways. Marta, Marco and Eva's daughter, arrives from America. Soon the balance will change.

Giulio and Livia, shocked by Carlo's refusal to work at the wine shop, become convinced that he's involved in shady dealings. Meanwhile, Walter tries to sabotage himself so as not to become Virginia's sous chef. Marta, increasingly obsessed with Jonathan, tries to make him jealous by showing herself and Olmo at the botanical garden, but obviously the plan fails. Despite themselves, the two young people are involved in a clandestine party, and Marco, called to intervene, is now truly angry with his daughter.

Giulio and Carlo try to help Adriano win over his beloved Federica. Their disastrous advice puts Adriano under pressure from his terrible partner Renato, but the arrival of Rovazzi will set things right! Walter supports Virginia in creating the new menu. Marco, discovering Marta's crush on Jonathan, creates a fake profile for him to talk to his daughter, unleashing the girl's ire. Father and daughter have just reconciled when Marta receives a call from Eva: she must return to New York immediately.

After yet another argument, Carlo leaves the restaurant; Giulio and Livia attempt to reconcile. Adriano, without filters, reveals truths that prompt Virginia to reflect. Marco and Marta leave for Milan to convince Eva to leave her in Rome; Olmo and Pedro plot long-distance support. Mimmo and Ines begin to open up, but an unexpected event calls into question.

To avoid foreclosure, Livia calls upon Aunt Teresa and organizes a fake wedding, with Stefania orchestrating. Marta and Olmo search for a common ground, a mixture of modesty and enthusiasm. In the kitchen, Virginia faces a crucial test cooking for Diana Canà, while Marco harbors a secret he confides only to Walter. Between masks and confessions, the family tests a new course.

Marco, increasingly gloomy after returning from Milan, alarms Adriano. Mimmo is down: things aren't going well with Ines. Preparations for Adriano's party are going badly: the toy car arrived broken and the location has been cancelled. Giulio and Carlo take matters into their own hands. Virginia sees a call on Walter's phone: her doubts about Marco's illness grow. Stefania suffers from love.

Marco, increasingly doubtful and tormented, hesitates to talk to Virginia. Lidia invites a chef to the restaurant to try Virginia's dishes, but, distracted by her problems with Marco, she fails. But Giulio, Lidia, and Carlo give her a second chance. Marco confesses; Virginia, hurt, walks away and leaves for a cooking internship.

Marco's confession overwhelms Virginia, who accepts the internship to get away. Giulio realizes the crisis is brewing when Carlo reveals the truth about Milan: he rushes to his son and entrusts the business to Carlo and Livia, with Adriano's help. A financial police audit forces a painful choice between friendship and the winery. Walter approaches Virginia to apologize and confess his feelings; Marco goes to her to clarify, but finds them in the same room. Exhausted, Giulio considers selling and closing down.
