Thursday, 20th July 1944. A foolproof plot to assassinate Hitler has failed on the same day that Major-General Paul Heinrich Gerhardt disappears from Germany and Colonel Hasso Jurgens puts a gun to his head and pulls the trigger. By choosing to commit suicide, Jurgens inadvertently points an accusatory finger at Gerhardt and sets in motion a remarkable chain of events. Two months later, Gerhardt appears in England to plot another assassination a killing that would collapse the German Home front, bring the German Underground into the open and give the Allies an easier passage into the country. The chance of success is remote, the chances of survival remoter as the chosen men make their way towards the Hall of Peace, Munster, on October 14th 1944.
