US soldiers Isaac and Matthews are stationed in Iraq after the war. After getting the assignment to inspect part of a pipeline, they make their way through the dessert. When they arrive at the spot all seems calm at first, but soon a sniper opens fire on them. Matthews is badly injured, and Isaac takes cover behind a stone wall. It’s now up to him to do anything he can to keep them safe from the invisible enemy chasing them. From the director of Edge of Tomorrow, Fair Game and The Bourne Identity.
