On our planet, men are confronted every day with social and environmental upheavals. How do they face it? Portraits of four ordinary heroes who have decided to take hold of their destiny. For nearly a year, we will follow four people who are in their everyday life facing issues of universal dimension. We will go to New York, meet a young designer from Mexico City determined by the Barack Obama election and who dreams of making herself a name in the fashion world. In the Tuamotu archipelago with Gervais and his family facing the rising waters in the Pacific. In Japan, with Taro Yamamoto, actor dedicated to children victims of Fukushima radiations. And finally, Ranohira, the first Malagasy town using solar energy.
