August 6th, 1945, 9.15 a.m. Six miles above Hiroshima, the bombardier of the Enola Gay releases an atomic bomb into the freezing skies. Seconds later, the city is obliterated in a single, monumental blast of fire. The destruction is immediate and catastrophic, as if a small sun had suddenly exploded. Tens of thousands of people are instantly annihilated. In that moment, the world will never be the same again.

Combining a rich array of interviews with gripping storytelling, Stephen Walker's Shockwave presents an extraordinary and unforgettably moving portrait of one of the defining events of the twentieth century.
