Lucas is a fighter in the Polish Resistance Movement during World War II. But when he wakes up in the trenches after a long night of being shelled, he finds his ears bloody and his memory gone. All he has left is a torn photograph of a man and woman and a young boy. Could the child be him? Four days later, on December 20, Lucas is dropped off on the train platform of a bombed-out Polish village. Nothing is familiar, though his buddies assure him that this was his home town. In the middle of death and destruction, Lucas begins the search for his family.
