Celia is a seven-year-old girl, belonging to a family of the Madrid bourgeoisie in the early years of the Republic. She is convinced that her mother is really a fairy, and that nothing can happen to her. As for her father, she thinks he is the most handsome and good man in the world. Celia's education is in charge of Miss Nelly, an austere Englishwoman, with whom the girl does not get along. The mother finds no better solution than to beg her childhood nanny, Doña Benita, to come take care of Celia.
