Savanna and the mountain

Once upon a time, there was a revolution in Covas do Barroso, a village in northern Portugal. A hybrid documentary in which, between songs and Western imagery, the villagers stage their own struggle - which is still going on - against the industrial project that threatens their land. The British firm Savannah Resources hopes to develop and exploit what would become the largest open-cast lithium mine in Europe. (Cannes Film Festival)
