Timewatch: The Gunpowder Plot

Documentary which re-examines the attempt to blow up the Houses of Parliament in 1605 - one of the most famous, yet least understood events in British history. It shows how the plot was almost England's 9/11, and asks why a group of young Englishmen became so radicalised and so hell-bent on terrorism. Computer graphics recreate what the Houses of Parliament looked like in 1605, and show just how close the plotters came to success. (BBC)
