An examination of the world of the Nun. Over the last ten years nuns have been directed to reconsider their attitudes to the values flowing from the three vows. Because of this they have come under enormous pressures and are in a state of anxious change. Tonight's documentary examines the inner world of the nun to discover what happens when women answer the irresistible call to serve God in the most complete way they know.
