This program follows the events of one night in the Blitz of 1940 when London was subjected to the most ferocious and terrifying attack of the war; 24,000 firebombs were dropped on the city, 45 tons of explosives. The story of the night is told through the written accounts of eye-witnesses and the memories of ordinary Londoners who survived it, one of whom lost his entire family when a public shelter was destroyed by a bomb.
