Aled Jones explores one of the most universal yet mysterious human activities: prayer. Among those he talks to are Archbishop Desmond Tutu and the Archbishop of Canterbury, Rowan Williams, who describes praying near the twin towers in New York on 9/11. The hymns, sung by the Exultate Singers, Tessera and Camilla Kerslake, include Make Me a Channel of Your Peace, Abide With Me and All My Hope on God Is Founded.
