Many things have been tried to solve ecological and economic crises. But not quite like this one. Fred and Laure decided to embark in a trailer with their two children, Martin and Chine, on a journey where theses crises were solvable. For five years, they filmed real solutions and those who put them into practice across 5 continents and 40 countries. The result is a window into the world of tomorrow, as it could be.
