Three years ago, an uprising against the Assad regime turned into what looked like a straightforward civil war between Syrian government forces and rebels. However, over time, what had started as a largely secular opposition movement began to take on more of a radical Islamist tone, with two al Qaeda offshoots — the Islamic State of Iraq and al-Sham (ISIS) and Jabhat al-Nusra — becoming the dominant forces on the ground across the rebel-held North.

One VICE filmmaker managed to secure unprecedented access to both al-Qaeda factions battling Syria’s government forces, despite the risk of journalists being kidnapped. This is a remarkable portrait of the foreign volunteers and local Syrians willing to fight and die to establish a new caliphate on Europe’s doorstep.
