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.

After a traumatic miscarriage, Lola and her husband, Adolfo, adopt Tin and Tina, a lovely albino brother and sister with an ultra-Catholic education that makes them interpret the Holy Bible verbatim.

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.

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.

Javier is what we have dubbed as a "husband-in-law." That is that without taking care of the care of the house and children at all, he knows exactly what needs to be done, and that he continuously collects a sum of sentences from the type: "It is that you do not organize", or "do not get nervous", you already consider that overflowing woman drowns in a glass of water. Javier will have to face the reality of dealing with five children (between four and twelve years old) when his wife decides to go on a trip and leave him alone with them. The chaotic situation that takes place at home will progressively evolve ecologically to the most absolute disaster, but at the same time it will give parents and children the opportunity to meet and enjoy themselves for the first time.

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.
