Once upon a time, it was necessary to have a weapon that could unleash hell. Britain hand-picked its healthiest and cleverest men to undertake a truly terrifying mission: to create and detonate an atomic bomb. Somehow, a country beset by post-war rationing and isolated from her allies created the most devastating weapons known to man, on the cheap and at the hurry-up. But it came at a horrifying price for them - and their families. The race to build a nuclear bomb sucked thousands into its vortex, who are still dealing with the effects of radiation today: veterans, widows, children, scientists and indigenous people, all subjected to fear, radiation, and experimentation. A black cloud still hangs over those who survive, and their descendants who fear the consequences of every fresh pregnancy. Exposed tells the complete story of the Cold War arms race, from inception to fallout, and for the first time reveals the blood-stained truth at the heart of the British state's longest criminal cover-up. Today, the UK's nuclear deterrent is a theoretical shield that shelters millions worldwide, protects it from aggressors, and guarantees its Prime Minister a seat at the top table. But for seven decades the veterans who created it have been denied truth and justice. As the handful of survivors launch a last-ditch legal bid for the answers, Exposed reveals the full price they paid for our peace and prosperity.
