When IRA Chief of Staff Mick O'Reilly, known as 'The Big Man', rescued the wounded Brendan Donnelly from under the noses of the British Paras the same night that his brother and top IRA marksman, Liam Donnelly, was shot and killed in the Falls Road, he had no idea that the same man would return ten years later with a plot that could destabilise the whole of the Western World - or that he would use his dead brother's thirteen year old son as a weapon of destruction. At the same time Salim Bin Gaafar, 'The Fist of Allah', is planning a multiple suicide bombing that would lead to the biggest loss of life on the United Kingdom mainland since the Second World War. Brigadier John Mason and his unofficial 'Crazy Gang' of top level operatives have only a very limited time to seek out and destroy both these threats to world order.
