A Shooter's War tells the narrative of a sniper whose anti-US beliefs prompted him to join pro-Russian rebels in the continuing Ukrainian conflict, which has become a major source of tension between the US and Russia. Deki's rival threatens to kill him when social media becomes a communication platform for scheduling sniper duels. Olya Schechter, a New York-based filmmaker, gains unprecedented access to military outposts and front-line fights to build an intimate image of a man straddling the moral tightrope that frequently comes with war: is Deki a soldier or a killer?
