The story begins as WikiLeaks founder Julian Assange (Benedict Cumberbatch) and his colleague Daniel Domscheit-Berg (Daniel Brühl) team up to become underground watchdogs of the privileged and powerful. On a shoestring, they create a platform that allows whistle-blowers to anonymously leak covert data, shining a light on the dark recesses of government secrets and corporate crimes. Soon, they are breaking more hard news than the world's most legendary media organizations combined. But when Assange and Berg gain access to the biggest trove of confidential intelligence documents in U.S. history, they battle each other and a defining question of our time: what are the costs of keeping secrets in a free society-and what are the costs of exposing them?

Yael Hersonski's powerful documentary achieves a remarkable feat through its penetrating look at another film-the now-infamous Nazi-produced film about the Warsaw Ghetto. Discovered after the war, the unfinished work, with no soundtrack, quickly became a resource for historians seeking an authentic record, despite its elaborate propagandistic construction. The later discovery of a long-missing reel complicated earlier readings, showing the manipulations of camera crews in these "everyday" scenes. Well-heeled Jews attending elegant dinners and theatricals (while callously stepping over the dead bodies of compatriots) now appeared as unwilling, but complicit, actors, alternately fearful and in denial of their looming fate.
