The documentary begins in 2005 with Robert Scott Kellner in Germany relating the story of his 1960 search for his grandparents , Justice Inspector Friedrich Kellner and his wife , Pauline . Photographs show Friedrich as a soldier in World War I , and as a political activist after the war for the Social Democratic Party of Germany ( SPD ) . Dramatic reenactments depict Kellner as he campaigns against Adolf Hitler and the Nazi Party . At his rallies , he holds a copy of Hitler ’s book , '' Mein Kampf '' , above his head and cries out : " Gutenberg , your printing press has been violated by this evil book . " Later , Kellner struggles to stop the mindless rampages of '' Kristallnacht '' , and as a consequence he is brought before a tribunal and threatened with imprisonment in a concentration camp . The film explores both his active and passive resistance during the Third Reich as he distributes Allied leaflets and risks his life to write the diary . When World War II comes to an end , Kellner helps to restore the Social Democratic Party and becomes the chairman of the party in his region
