International Documentary Film Festival Amsterdam (IDFA) 2020 will open with the world premiere of Nothing but the Sun by Paraguayan-Swiss director Arami Ullón. A quietly earth-shattering film, Nothing but the Sun lucidly contrasts the hot, arid atmosphere of Paraguay’s Chaco region with the devastating stories of the Ayoreo people, an Indigenous community violently uprooted from their ancestral territory by white missionaries. Between past and present, forest and desert, folk songs and church hymns, Ullón’s poetic feature lays bare the raw emotions of the human condition, seen through a culture on the brink of disappearing, but not without a voice.
