June 1944. Allied Forces stand on the brink: a million soldiers are secretly assembled on the south coast of Britain, poised to invade Nazi-occupied Europe. One man stands in their way: Winston Churchill. Fearful of repeating, on his disastrous command, the mass slaughter of 1915, when over 500,000 soldiers were killed on the beaches of Gallipoli. Exhausted by years of war and plagued by depression, Churchill is a shadow of the hero who has resisted Hitler’s Blitzkrieg. Should the D-Day landings fail, he is terrified he’ll be remembered as the architect of carnage. Only the unflinching support of Churchill’s brilliant, unflappable wife Clementine can halt the Prime Minister’s physical and mental collapse.
