Marina, a very unusual nun, arrives in the summer of 1994 at El Parral, a school threatened with closure. Despite the fact that the interns, boys without families, receive her with a thousand pranks, Marina has an idea that will change everything: form a soccer team. With the help of two nuns: Angelines, innocent and fragile, and Tatiana, brutish and kind, she will create something like a real family. Years later, Valdo, one of the boys, will make his debut in the Real Madrid first team.
