Man with a Gun Over There

Two soldiers, Ernst and his chief Mackheath are ordered to guard a Outpost at the border in the middle of nowhere. Soon both of them begin to doubt the reasons why they are there. After Mackheats dies in an accident with a land mine he had set up the same day, Ernst stays alone. His only companions are a turtle that seems to magically travel between the two sides of the border river and the feeling that someone is watching from the other side.
