In the romantic Unknown Soldier, a timeless search for lost love crosses two generations: Lucie Rabinowitz searches for the truth hidden in her grandmother Lucy's past while 80 year earlier Lucy searches for the love she thought stolen by the horrors of The Great War. The searches lead both women to the same lost young man, a fragile unknown soldier. This intimate musical examines the past and our memory, what we choose to forget and what we can't help remembering.
