A small group of soldiers from one of the warring sides, breaking away from the main forces and wandering through the desolate devastated countryside, stumbles upon several young women refugees and takes them under their patronage. It is clear that the soldiers are motivated not by humanism but by the most carnal of motives. All the usual moral standards have been shattered in the flames of war, and in front of the eyes of the young Moë, the youngest of the refugees, ugly and disgusting scenes are played out. The women are trying at all costs to protect a little girl who has suffered violence in the past from the soldiers, which makes her mind a little clouded. Events take an abrupt turn when an enemy sniper appears in the area, keeping up with the group and slowly but surely stabbing both rapists and their victims...
