In 13th century Italy, Francis Bernardone, the son of an Assisi merchant, renounces a promising army career in favor of a monastic life and starts his own religious order, sanctioned by the Pope.

Francis Bernardone (Bradford Dillman) is the son of a wealthy cloth merchant in Assisi, who gives up all his worldly goods to dedicate himself to God. Clare (Dolores Hart) is a young aristocratic woman who, according to the film, is so taken with St. Francis that she leaves her family and becomes a nun. By this time (1212 A.D.), St. Francis has a well-established reputation for his vows of poverty. The movie goes on to note miracles (such as the appearance of the stigmata on Francis's hands and feet) and other aspects of his life, up to and including his death on October 3, 1226.—Anonymous
