Love in a time of war, separation, loneliness, the desperate will to do the right thing; there are many different kinds of battle. It's 1915, and Jim Errington wants to stay at home with his young wife, Elsie, but is driven by duty to leave and begin training as an officer. Ivan, his brother, stays in Northumberland near Elsie, who loves them both. Riven apart by the Great War, the family is drawn into a different conflict, with far reaching consequences.
