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.

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.
