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.
