In the first episode, Peter hears from those convicted under Britain's newest anti-terror laws and investigates how some of the most notorious terrorists came to be radicalised. He finds a generation that has shed the moderate Islam their parents brought to this country, and instead have adopted a faith that they believe compels them to stand apart from Britain and its values.
In the second part of this series Peter Taylor investigates how young Muslims radicalised over the internet formed themselves into a terror network that spread across three continents. Aided and abetted by two young fanatics in Britain, these cells plotted major attacks in Europe and America - culminating in a plan to explode three enormous truck bombs which, it was claimed, would dwarf the London bombings of 7/7.
Peter Taylor investigates what Britain is doing to counter the threat of violent extremism. In 2010, 140 million pounds will be spent to win the battle for the hearts and minds of young Muslims, but the policy risks alienating many in Britain's Muslim communities. With unique access to a man who came face to face with al-Qaeda and the inside story of how police managed to thwart would-be suicide bombers, the programme examines the biggest single threat to national security.
