Sacha and Vanya are two Russian soldiers with vastly different life experiences. One is young and has only just become a soldier, while the other is older and has seen a great deal of the unpleasantness that war can bring. Both of them are captured by a Muslim father and taken to his home in the mountains. His aim is to trade them for his son, who is being held prisoner by the Russians. In the midst of their upsetting ordeal, they will begin to understand more acutely the battle they're fighting and even develop some empathy for their captor.
