The first chapter of Antonin Baudry’s two-part historical epic.

A powerful account of Charles de Gaulle's journey during World War II, from his rise as a military leader to his emergence in French politics between 1940-1945.

In the 72 hours leading up to D-Day, all the pieces are in place except for one key element – the British weather. Britain’s chief meteorological officer James Stagg (Andrew Scott) is called upon to deliver the most consequential forecast in history, locking him into a tense standoff with the entire Allied leadership. The wrong conditions could devastate the largest ever seaborne invasion, while any delay risks German intelligence catching on.

With only his trusted aide Captain Kay Summersby (Kerry Condon) to confide in, and haunted by a catastrophic D-Day rehearsal, the final decision rests with Supreme Allied Commander Dwight D. Eisenhower (Brendan Fraser). With only hours to go, the fate of the war and the lives of millions hang in the balance.
