Young Westerners leaving comfortable lives to fight and die for jihadist causes is not new, despite the shock generated by ISIS recruits in the 2010s; for three generations, Europeans have joined mujahideen movements in Afghanistan, Bosnia, Kashmir, Chechnya, and Burma. Director Deeyah Khan, who has herself received threats from extremist fundamentalists, spends two years tracing that history through the people who lived it. She sits with former British jihadis from earlier generations, including one of the founding figures of the British jihad movement, a man who fought abroad and preached extremism to thousands of young Muslims across the UK. Their testimony is raw and often unflinching about how radicalization actually works and what it costs afterward. Khan then moves to present-day Britain, talking with young Muslims caught between the War on Terror and communities that reject them, hearing about discrimination and identity crises firsthand. The film does not treat radicalization as a single mystery but as a recurring pattern, and it looks for what, if anything, breaks the cycle.
