Frontera Invisible is the true story of communities trapped in the middle of the world's longest war, in which big business' rush for palm oil to produce 'green' fuel has displaced peasant farmers and indigenous people, destroyed natural habitats and concentrated land in the hand of 'the rich'. Colombia is on the cusp of a peace deal that will end 60 years of armed conflict. A war that has displaced more people than the entire population of Denmark. Meanwhile, the government plans to keep planting palm to supply Colombia and Europe with 'biodiesel'. Will peace return the land to its true owners or hand it over to big agribusiness? A fine blend of environmental documentary and social research through victims' testimonials, Frontera Invisible gives a voice to the local communities that fight hard to recuperate their land while exposing the major pitfalls of the biofuels policy.
