The decision to be a saint (or at least a martyr) takes Celia to crazy extremes, against which Don Restituto, the priest, fights. End of year exams are a disaster. One of the nuns devises a trick so that the mother superior asks, in the presence of the families, and each girl answers what is necessary. But for some reason, the plan is changed, and the girls give improbable answers to the general glee. Celia believes she is obliged, on behalf of the teacher, to explain what happened, which aggravates the situation.
