Love knows no age, nor does paternity know sexual orientation. Alfonso falls in love with Carmen, just as he did with Roberto, his father. Myriam, his mother, has a relationship with Manu, much younger than her, even younger than her own son. Miguel is Carlos' son, he did not know his mother, he has a sentimental relationship with Julio and both want to be parents with a couple of lesbian friends.

Roberto is a retired man who lives alone and rents a room in his house to a young student, Carmen, who soon begins to fascinate him; he spreads the joy of his new life to Carlos, an even older friend than him, who also decides to rent a room to another young girl, Sonia, who aspires to be a soccer player despite her dissolute life.
