Ambushed in late 1939 by British cruisers off the coast of Uruguay, Hitler's prized "pocket battleship" and high-tech wonder, the "Admiral Graf Spee," was blown up by its captain, Hans Langsdorff, who then committed suicide. This documentary retraces the events that led to the ship's destruction. Along with high-end re-enactments, CGI reconstructions made after original plans from the Third Reich's secret archives, and surprising findings by naval researchers shed light into this mystery.
