Entrenched in the so-called Atlantic wall, the Nazi troops await the imminent allied invasion. In England the largest Armada the world has ever known is being prepared, men and machines meet in a quantity never seen before. At the beginning of the summer of 1944, a Spanish professor, exiled after fighting on the Republican side, warned that the Germans had a new and terrifying weapon; a devastating weapon, whose creator, a Jewish scientist, assures that it can end with a single explosion with all the troops stationed in the south of England. The Allied High Command is skeptical. But this is not the time to take unnecessary risks and, at the remote possibility, Winston Churchill organizes a command mission. Directed by an atypical American colonel, and made up of hopeless men, they must enter Nazi Germany and find and end with the threat of the Jewish physicist and his bomb. D-Day is approaching, and nothing and no one should warn planned final assault on the European fortress of Adolf Hitler.
