Jamie Roberts’ documentary, shot over a span of two years, offers a close examination of individuals promoting extremist fundamentalism in Britain. In 2014, Roberts captured footage of Islamic extremist Abu Rumaysah, who has since become one of the globe’s most sought-after individuals and is believed to be the British jihadi featured in the latest IS execution video. This film provides remarkable insight into a new generation of extremists, including Rumaysah, who are influencing and recruiting young British Muslims. It questions whether their professed non-violent intentions are genuine or if they pose a real danger to society.
