It is based upon the true story of Helmuth Hübener, the youngest person to be sentenced to death by the Nazis during World War II.

He begins to secretly listen to forbidden enemy radio broadcasts and enlists the help of two of his closest friends in distributing anti-Nazi pamphlets.

Although originally proud of the Fatherland and an enthusiastic participant in the Jungvolk, the Hitler Youth group, Helmuth became disillusioned as Nazi power and policies spread in Germany.

Helmuth and a group of friends including Karl-Heinz Schnibbe, Rudolf Wobbe, and Gerhard Duwer, monitored banned radio broadcasts, in which the Allied Powers gave an accurate portrayal of the war in Europe rather than the version told through Axis propaganda.

The book includes the author's note, pictures, a copy of the poster announcing Helmuth Hübener's execution, a 1936 map of Europe, and a Third Reich timeline, 1918–1945.
