The true story of a Portuguese nobleman who, against his father's wishes, chooses the convent instead of joining his peers for the war. Antonio thus passes from the status of hidalgo to that of humble brother, disciple of Saint Francis, servant of the Church by word rather than by sword. By his vigorous preaching, he fought pride and usury, gathering around him other Franciscan friars, from Portugal to Sicily, from Africa to Greece, from Assisi to Padua, and giving his Order European prestige.
