June, 1940. France collapses and signs the armistice. In the midst of the chaos, one man refuses to give up. Alone against the odds, this unknown general flees to London to save what remains of freedom. Without an army, without backing, without hope. But with one irrational conviction – France, his France, has not laid down arms.

Taking the ultimate gamble, he seeks to convince the world that the battle for France is neither over, nor lost. Reality, however, is unyielding and seems determined to prove him wrong. Yet, little by little, resistance fighters, rebellious students and determined soldiers rise up in England, France and Africa to join the cause.

Boasting an incredible international ensemble cast including Simon Russell Beale (The Death of Stalin) as Winston Churchill and Lambert Wilson (Mrs. Harris Goes to Paris), this breathless, beautifully shot drama explores the audacity, personal cost, and conviction required to spark a global resistance movement.
