During the last days of Stalin’s reign, a doctor (Marina Hands) tries to go unnoticed in a society of mutual dread where a neighbour or colleague might “denounce” you to the authorities at any moment.But tales of her healing touch have spread and one night she is taken away, not to the infamous Lubyanka prison, but to the Kremlin to attend the ailing Comrade Stalin himself. Uncle Joe (André Dussollier), an old man racked with pain but still as watchful and deadly as a snake.

Jamie Roberts’ documentary filmed over the course of two years, which takes an intimate look at the people spreading extremist fundamentalism in Britain. In 2014 Roberts filmed Islamic extremist Abu Rumaysah, who is now one of the world’s most wanted men and is suspected of being the British jihadi in the latest IS execution video. This film gains extraordinary access to a new wave of extremists, including Rumaysah, who are radicalising and grooming young British Muslims, and asks whether they really have non-violent aims, as they claim, or are a genuine threat to society.
