Oscar nominee David Strathairn plays Jan Karski, a Polish officer who, after surviving the disaster caused by the Blitzkrieg, swears allegiance to the resistance and risks his life to bring accounts of the Shoah from war-torn Poland to the free world, all the way to Washington. Escaping from a Gestapo prison and describing the drama of the Warsaw Ghetto, Karski becomes a witness to truth and moral courage. His story still shakes the conscience of the world.
