As she chases the truth about the soldier featured in the photo, Ellen is drawn into a tangle of historical facts and mysteries that lead her to surprising love stories and unexpected truths. Unknown Soldier delves into memory and family mythology, asking how – or even whether – the past shows us who we are."
