They leave profound traces on a vast continent. They fear neither wind nor weather and resist attackers resolutely. They protect and give life. They discover ancient ways that lead into the future. They are adventurers, pioneers and visionaries and, with every step, they write NATURAL HISTORY.The shepherds of transhumance and their barely manageable flocks. They are: EUROPE’S LAST NOMADS.The behavioral patterns of the actors - whether human or animal - can be projected on to a map of modern Europe. A Europe in motion. A Europe of trust, and distrust. Of mutual dependence. A Europe with open borders, but one where everyone wants to preserve his own identity.Our film is a story of survival, but also a story about life. Told by humans and animals from diverse cultures, who all excel to reach a common goal - every year, following a tradition without which they would all be lost: Nomadic pastoralism along ancient paths - deeply rooted in Europe’s soil.
