June 1940. France collapses and signs the armistice. Amid the chaos, one man refuses to yield. Alone against all, this unknown general makes his escape to London to save what remains of a dream: freedom. Without an army, without support, without hope. But with a fierce conviction: France, his France, has not laid down its arms. He makes one last gamble: to convince the world that the Battle of France is neither over nor lost. Reality is stubborn and proves him wrong. But little by little, in England, France and Africa, clandestine resistance fighters, rebellious high-school students and determined soldiers rise up around him. Their faith, their audacity, their fierce hunger for freedom defy history, which had seemed written in advance.
