Pamplona, 1975: Dr. Navarro, a famous doctor in the city, feels strongly attracted to Juana, his nurse, who is also in love with the doctor. Navarro, however, moved by his strong religious convictions (in fact, he is a numerary member of Opus Dei) remains faithful to his wife and tries by all means to prevent that their relations with Juana break through professional boundaries. For the purpose of that, he orders the nurse will sent to another hospital. This will push Juana to take the initiative and provoke the doctor during San Fermines.
