After taking over a ramshackle little hotel, bought by mistake at an auction for an exorbitant price, the Garcias live a new adventure, helped, much to their regret, by a group of gifted children who are staying at the hotel to attend the Talent Final. Together they will confront the mafioso Benito Camarena, who will try to snatch the loot hidden in the hotel from the Garcias.

Christmas is coming. The children accidentally break a Nativity scene figurine from their father's collection and must by all means get an equal one, the problem is that it is a unique antique piece. Sara, the eldest daughter breaks up with her boyfriend, Ocho, who will try to recover her favors with the help of her father-in-law, Javier. Precisely Javier's father-in-law, Marisa's father, will be welcomed into the family home to spend the holidays after her recent separation, which will not leave Javier's mother, Milagros, indifferent. Rocío, the folklore of the family, who has been playing the Virgin for several Christmases, is relegated this year to playing the shepherdess, something that her father, Javier, is not willing to assume.

A year ago, Ricardo and Felipe, in charge of taking the children to a camp, stayed outside the train leaving the children inside. Clara no longer trusts them and this year she decides to take the children personally with the help of her friend Susana. However, now they will be the ones who, as a result of an accident, are separated from the children.

The eldest of the family, Sara, comes of age and brings chaos to the family by announcing her intention to marry Ocho. Javier and Marisa try to avoid it at all costs. At the same time Dani has an existential crisis, Paulita feels jealous of Cris, Carlota announces that she has found a boyfriend from a high society family and Rocio has finally managed to be cast in her first film.

Some parents experience the anguish of the "empty nest" when their children leave home. Javier, on the other hand, suffers the trauma of the "full nest": no one wants to leave home.

The success of the Conchy virtual assistant (which was developed by Javier) has earned him a favorable spot in the parents chat room - until something unexpected ruins it all.

When Ricardo, a responsible father, decides to personally take his son to a camp in Asturias, other parents propose that he should also take care of their children. When the train is about to leave, Felipe, a flamboyant individual and grandfather of two of the children, shows up at the station.

A 10-year-old girl, Ana, and her future stepmother Sara, who's about to marry her father, switch bodies due to strange magic during an unusual weather phenomenon.
