Season 4

There's a lot of news in the Martini household: Maria and Guido have been engaged for two years, and Guido travels back and forth between Rome and Milan. Ciccio still plays rugby and is engaged to an English girl named Emma and... Grandpa Libero is called to school because Annuccia wrote a decidedly strange essay about family. Maria rents a house for herself and Guido, but discovers that, for now, he's forced to stay in Milan.

Meanwhile, Guido is sad because he has to stay in Milan for another two years and doesn't know how to tell Maria, who is currently interning at the local health authority. On the way to Milan, he has an accident. Maria misses Guido greatly and is considering continuing her studies in Milan, at least until graduation. Guido, meanwhile, is trying every way to get a transfer, but it seems hopeless.

Cettina and Torello's house is now finished, but Cettina is in for some unpleasant surprises. Maria and Guido have decided to move in together, and to keep them from moving far away, Cettina finds an unexpected solution. The family decides to give Guido and Maria a hot tub and a Bohemian crystal chandelier, but the children get angry because they want to furnish the house themselves. The first arguments arise.

Among friends and family, Guido and Maria can't find a moment of peace at home, and this certainly isn't good for the couple. Grandpa Libero, however, due to a series of misunderstandings, thinks Ciccio is taking drugs. Grandpa Nicola makes a grand comeback, but the reality is very different from what he pretends. He invites Maria on a cruise, and she, who initially refuses, eventually realizes that all her grandfather has left is family affection.

While Marcello feels attracted to Eufrasia, Torello's nephew arrives in Rome, whom Cettina welcomes like a son. Cettina asks Torello to bring his grandson Rosalbo into the partnership, but one night they overhear him plotting against them on the phone. The two decide to make life impossible.

Cettina doesn't know how to tell Torello that she's not actually pregnant because he's showering her with attention, arranging everything for the future baby. During an ultrasound, she steals a video showing triplets to play along. Libero is worried about Olindo, an old friend of his who's been missing for days. He learns that he's in a nursing home and can't even talk to him or find out how he's doing. Libero then asks Guido to do an inspection.

Maria has returned from her cruise, and Guido immediately showers her with affection, so much so that the entire Martini family catches them soaking in the hot tub. Meanwhile, Cettina has a truly horrifying experience. Guido is anxious because he has to present the project for the family hospital, but Maria forgets the interviews with the local health authority. But the troubles aren't over: her scooter doesn't work, and it's a race against time.

Reby tells the Martinis that she's getting married to a Japanese designer she met the week before. Maria isn't convinced, knowing her friend's quick crush, but this time it seems serious. Guido finds a pregnancy test, actually belonging to Reby, and, frightened by something he feels is bigger than him, runs away and leaves a note for Maria. Having heard nothing from him for two days, Maria is heartbroken.

A man very similar to Grandpa Libero has been wandering around the Martini house for a few days, and trouble begins for Grandpa: everyone is starting to think he's seriously getting old and can't remember things.

After three years away, Lele returns to the Martini household, finding the situation more than a little unsettling.
