Angola, 1974, the thirteenth year of the liberation war: the Portuguese and their descendants flee the colony, where independentist groups gradually lay claim to their territory. A group of Portuguese soldiers who are barracked inside an infinite wall will have to escape from they camp once the past comes out of the grave to claim its long awaited justice. Borrowing its original title from the lyrics of Portugal’s national anthem, this visually arresting and uncompromising film is at once a relentless study of colonialism and a parable of the devastation of warfare.
