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. Nação Valente gives a dual perspective on this struggle: a tribal girl who discovers love and death when her path crosses that of a young Portuguese soldier; and a group of Portuguese soldiers who are barracked inside an infinite wall from which they will have to escape once the past comes out of the grave to claim its long awaited justice.

A Terratreme production, Portuguese filmmaker Carlos Conceição's daring sophomore feature premiered at the Locarno Fim Festival before touring in festivals and venues across continents.
