In the second segment, Wood explores the greatest British myth: the tale of King Arthur and the Knights of the Round Table. Traveling around the Celtic world from Cornwall to Wales, Brittany, Ireland and Scotland, Wood uncovers the extraordinary story of how a shadowy Welsh freedom fighter — a Dark Age Che Guevara — became a medieval superman and, finally, the model of a Christian hero. On the way, viewers discover the real stories behind the Round Table, Excalibur and the Holy Grail itself: the unattainable, mystical cup of Christ, which has inspired poets, novelists and filmmakers from the Middle Ages right down to Indiana Jones, Monty Python and The Da Vinci Code. In an intriguing piece of historical detective work, Wood offers a tantalizing glimpse of a historical Arthur — but in the unlikeliest of places.
