ISIL's leadership has redirected its rhetoric away from the West and toward Russia, and this Al Jazeera film follows the fighters and officials caught up in that shift. Cameras get access to ISIL commanders and women fighters regrouping in the mountains of northern Afghanistan, where they describe plans to move units north through the Caucasus toward Moscow and St. Petersburg. The film traces the grievance back to the Soviet-Afghan war, the decade of fighting that pushed out Moscow's army in 1989 and left the vacuum that produced the Taliban, al-Qaeda, and eventually ISIL. A metro bombing in St. Petersburg, carried out by a lone attacker with a TNT device packed with shrapnel that killed 15 people, becomes the film's proof of vulnerability. Zubair Massoud, nephew of Ahmad Shah Massoud and an adviser to Afghanistan's National Security Council, warns of fighters massing at an exponential rate, while Putin's envoy Zamir Kabulov downplays the threat. The film sits between those two assessments and lets the fighters' own statements make the case.
