Straddling a 2,400-kilometer-long wall constructed by the Moroccan army, the Western Sahara is today divided into two sections — one occupied by Morocco, the other under the control of the Sahrawi National Liberation Movement’s Polisario Front. Drawing from stories of flight, exile, interminable waiting and the arrested, persecuted lives on both sides of that wall, this film bears witness to the Sahrawi people, their land, their entrapment in other people’s dreams. In an esthetic that sublimates the real, Lost Land resonates like a score that juxtaposes sonorous landscapes, black-and-white portraits and nomadic poetics.
