Discover the ancient farming practice of transhumance in Spain. Following Jesús “Suso” Garzón as he and his fellow shepherds herd their flock of sheep and goats from the stunning mountain pastures of Cantabria, across idyllic plains and rivers, to end up crossing the centre of Madrid, the film will highlight how this unique traditional technique of raising animals not only reduces their impact on the planet, but actively creates new life and improves ecosystems.
