Sebas is a local police officer who is happily married to Lola, the mother of his sons Nata and Alex. Everything changes when he discovers that he has been unfaithful to his best friend Agus. It will be so that the police decide to move in with the two neighbours in front and to spend more time with his teenage children. Little by little, Sebas will learn to live with two friends as different as Olivia and Ana, as well as see how his old brother-in-law Teo continues to live with his mother and how the godparents of his sons Pascual and Charo govern the bar and pharmacy in the neighborhood, respectively. In case there is little, the police will receive two new members: Jorge as a colleague of Sebas and an inexperienced police.
