At the beginning of the Second World War more than three hundred British and allied soldiers are being miraculously rescued during the Dunkirk operation. The story starts when thousands of soldiers find themselves trapped on the beach. As they get back on the sea they face an impossible situation, but the enemy's strength never stops to grow.
It's a curious mix of old fashioned mawkishness, dewy eyed, if understated, patriotism, and contemporary art house narratological experimentation. It is, appropriately, very British (as we like to think of ourselves).
Christopher Nolan's genius for treating movies like chess matches... is brilliantly employed in this account of the British (and French) attempt to retreat across the English Channel from the coastal city of Dunkirk in the early years of World War II.
