In the winter of 1862, during the American Civil War, a group of volunteer soldiers explores uncharted territory in the western part of the country. Far from the front lines, their task mainly consists of waiting: for orders, for other troops, or for an attack. As these men from various backgrounds set up camp, play baseball, and play cards, they reflect on God, life, and the purpose of their mission. When the enemy finally strikes, the harsh nature of Montana proves to be just as deadly as their fellow human beings.
