Quod Erat Demonstrandum

In 1984, a brilliant mathematician becomes the target of the Secret Police after he published an article in an American journal without asking for permission from the Communist authorities. His best friend’s wife and colleague is trying to join her husband who emigrated to France. And then there’s the Securitate agent who’s investigating both of them. What follows is a tense story of paranoia and betrayal, skillfully shot in black and white with remarkable attention to period details, where the issues explored are anything but black and white. As A.O. Scott put it in The New York Times: “The villains here are sincere, hard-working bureaucrats, and their victims are frequently confused or duplicitous.” A New Directors/New Films selection.
