Una familia de diez

Plácido López is a middle-class accountant who is tiring of being the sole provider for his family, his wife Renata and his 2 children, Plutarco and Martina. They live very happy in a small apartment in the Colonia Doctores in Mexico City.

Five years ago, Aunt Licha and her daughter (whom they call La Nena) have arrived since both were abandoned by her husband, after he "uncovered" as homosexual. Then a year ago, Don Arnoldo López, Plácido's father, moved to live with them since he has nowhere else to go.

Subsequently, an indigenous named Tecla is integrated, who comes from the same town where Don Arnoldo lived ("Apaseo el Grande") and by accident makes constant references about Don Arnoldo having a secret relationship with her mother.

Placido works in a company that belongs to Don Justo Del Valle (a very rich man), who has a daughter named Gabriela del Valle (Gaby) from whom Plutarco falls deeply and instantly in love. Plutarco and Gaby marry secretly, after they learn that they will become parents, which is why Gaby moves in with the López family. A few chapters later, Aldolfo, La Nena's boyfriend also arrives and moves in, after finding out that La Nena is also pregnant.

Thus, in a short time, the tranquility of the López home becomes an agglomeration of ten people in the small apartment. There is endless fun and funny problems, mainly derived from the lack of space, economic problems and the ingenuity and humor of each of the characters as well as some other sporadic characters that give a special touch to this series. In the final episode of the series, due to good luck, in a television contest, the López win a house.[6]

In season two, after the house they won more than ten years ago burns down, they are now forced to return to the apartment where they lived before. But, now with two new members, the children of Plutarco & Gaby (Justito), La Nena & Aldolfo (Victoria), the López family will live new troubles and problems, which will be solve with the support of the whole family.
