The life of Saint Francis of Assisi (Aldo Fabrizi) is loosely chronicled in this film, divided into nine chapters that highlight different elements of the saint's teachings, from compassion to humility. Director Roberto Rossellini's film, which conveys the joy Saint Francis found in seeking out enlightenment, opens with an introduction to the saint's followers, the Franciscans, and closes with the holy friar leaving Rome to spread his views to the world.
