Between September 1939 and September 1945, the Second World War claimed 27,000 victims a day. 67 months of struggle during which there were more civilian victims than soldiers, and more victims among the victors than the vanquished.

Along with interviews with experts and witnesses, the series draws on rare and never-before-seen images, and uses animated maps and imaginative infographics. A new look at the Second World War.
