Fratello sole, sorella luna

Francis (Graham Faulkner) is the son of wealthy merchants, and enjoys his share of wine, women and song without serious thought. When war and disease devastate his neighborhood, Francis undergoes an anguished transformation which culminates in his appearing before the local bishop and removing his clothes to renounce his previous life and family before dedicating himself to God. The culminating dramatic moment is Francis' appearance before Pope Innocent III (Sir Alec Guinness), to make his case for an independent religious order under new rules.
