Nonno Libero has finally returned to Poggio Fiorito. Immediately, Marco and Maria announce their marriage, which will take place in two weeks. For the occasion, the grandfather has a special surprise in store: to hire Al Bano!

The proposal to buy the Aurora clinic forces Lele to tell the truth about the house they are about to take from him. The Martini family, informed, takes action.

For the Martinis the situation is critical. Really risking losing the house, grandfather Libero goes on the trail of the builder who cheated them.

For grandfather Libero, the loss of the house is such a serious threat that it even interferes with his own health. After his reluctance to sell used items at the neighborhood market, the family convinces him that everything is fine.

Lele finds herself clandestinely treating an old patient of hers. With great risk, she decides to start visiting clandestinely those patients who cannot adjust to the too high prices of the Clinic.

Annuccia starts the part-time job of pony express in order not to ask her father Lele for money for the international class trip. She finds herself in a seedy neighborhood when thugs harass her.

Relations between Bianca and her mother worsen under the sorry eyes of Inge, who is really fond of her grandmother. Meanwhile Marco lies to Maria about the new assignment he has received.

As if they weren't troubled enough already, the Martinis have to re-roof their house. It's not exactly the right time economically, and the family is really worried.

Lele and Bianca discuss it and believe it is necessary to fire the gardener, who has been tending the garden of the villa for years, but Melina, overhearing the conversation, believes that she will be fired. So she immediately gets busy.

Marco returns to Rome and Maria picks him up at the airport. Unexpectedly, his colleague Antonia is also with him. Lying once again to her girlfriend, Marco manages to get away with a lie, but Maria begins to suspect.

Lele and Bianca discuss the future of the Martini house and therefore decide to look for new accommodation. However, the news is not well received by the children, who decide to occupy the house, without the knowledge of the whole family.

Marco gives Maria the engagement ring, and promises her that they will get married immediately after her last departure for Brussels. Meanwhile at Villa Aurora, Lele and Guenda seem to get closer, after she shows the human side of her.

Maria has no idea where Marco is and therefore takes it upon herself to authorize the operation on little Jonathan. She discovers the bitter truth: Marco lied to her, continuing to shoot documentaries in war zones.

Marco returns to Rome and Maria is waiting for him at the airport, but only to inform him that it is definitely over between them. Both back home, the situation seems to improve: but how long will it last?

Between Marco and Maria it seems to get worse and worse, so much so that he goes home early in the morning to make the children believe that he still lives with them. Nonno Libero notices the situation and promises to help him.

Inge, seeing her father increasingly sad, decides to arrange a meeting with the estranged mother of a schoolmate of hers. However, the appointment falls apart and the woman suffers from anaphylactic shock.

Maria seems more than ever willing to embark on a relationship with Roberto, however continuing to hide everything from Marco, who begins to suspect.

The story between Maria and Roberto seems to continue at its best, but when she discovers that Palù has bitten her friend, showing an aggressive attitude that had never been shown before, she understands that the little girl is suffering.

Marco is in danger of losing custody of Jonathan, but Maria offers to help him. The situation becomes more complicated in this way, because now Marco and Maria are forced to organize a fake wedding.

Marco and Maria with the help of the family manage to convince the assistant. Everything could be resolved, were it not for the fact that Micol threatens them: if the wedding doesn't take place, she will do everything to get the baby back.

Marco and Maria announce to their children that when the two return from the camp organized by the school, each will go his own way. At this point Maria can devote herself to Roberto and introduce him to the family.

While Maria is in the car to join her daughter at the campsite, her car breaks down. So she decides to call Roberto, but just at that moment Marco arrives and offers to accompany her.

Lele helps Maria clear her head and the young woman understands that her heart actually beats for Marco. Unfortunately Roberto's father is on the brink of bankruptcy and Maria doesn't feel like leaving him now.

Everything seems to turn out for the best: Lele manages to buy back the house with the money he got in Paris thanks to Bianca's broadcast, while Maria, after having clarified her doubts, will go back to Marco. And Roberto?

As they are about to cut off electricity and gas at the Martini house, the family decides to leave before everything ends before their eyes. But there's still time to plan a surprise wedding for Maria.
