A former policeman enlists his nerdy friend to help bust drug traffickers moving heroin through a Chinese restaurant.

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.

Years have passed since his last adventure, but José Luis Torrente, the most politically incorrect former cop in Spain, still sees himself as a national hero.

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.

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.
