High up in the mountains of the southern Massif Central in France lie tiny, remote villages united by a long and particular history. During the Nazi occupation, the inhabitants of Le Chambon-sur-Lignon and the other villages of the Plateau Vivarais Lignon saved several thousand people from the concentration camps. There were no informers, no denunciations, and no one broke ranks. Together, the villagers held their silence, and kept persecuted people - resisters, freemasons, communists and above all Jews, many of them children and babies - from danger. This title tells a story of courage and determination, of a small number of heroic individuals who risked their lives to save others, and of what can be done when people come together to oppose tyranny.
