 Marita (Maria Gracia), a charming little girl, lives in the country with his grandmother. Her best friend is a modest servant, Anselmo (Jorge Martínez de Hoyos), who almost everyday takes the girl to visit the church known as "Guadalupe s Basilica", an important temple in Mexico City, where she discovers Virgin Guadalupe and the legend about her apparitions in that place. Marita doesn t behave properly in school, and her teacher always has a punishment for the girl. She doesn t like school, and she doesn t want to return to school anymore. Besides, Marita s worry about her animals, like a cow, who doesn t produce milk. The girl asks many miracles to Virgin Guadalupe, one of them is not going to school. During a visit to Basilica, Marita hears the Virgin s voice, and this could be the beginning of a responsible life for the girl, like to study and to be a good child.
