Nazi Germany's weapons labs spent the war chasing designs meant to reverse a losing position: rockets capable of reaching the United States, jet-powered aircraft faster than anything the Allies flew, and armor built to shrug off tank fire. This film walks through the blueprints behind those projects, with historians and engineers comparing German designs against the technology Britain and America actually had in the field at the time. Archival test footage shows some of these machines in action, revolutionary by the standards of the early 1940s even where they never reached full production. The film gives particular attention to the German atomic program, laying out how far scientists got toward a working bomb and what stopped them. It also takes seriously the counterargument: that pouring scarce resources into speculative wonder weapons pulled effort away from the fighting Germany actually needed to win, and may have hastened the defeat it was meant to prevent. The picture that emerges is less a story of secret superweapons than one of ambition outrunning capacity.
