A year after the Islamic State seized Mosul, Iraq's second-largest city, the Kurdish Peshmerga are the only ground force still holding the line against them in the north. VICE News reporter Aris Roussinos spends a month embedded with Peshmerga units defending a 600-mile front that almost encircles Mosul, filming from hilltop positions near Sinjar, where IS controls roughly 77 percent of the surrounding region. Soldiers rotate through ten-day shifts on the high ground, watching for the truckloads of arms and fighters moving between IS outposts below and trading fire that shows up on camera as sweeping points of light across a night sky. The crew catches Peshmerga positions under direct attack and is eventually evacuated when sniper fire gets too close to keep filming. Fighters describe growing up around war and say morale stays high despite thin supplies of ammunition and modern weapons, and several voice hope that international support will eventually match what they're giving the coalition. The film closes with the frontline still holding and the outcome still undecided.
