Two secret agents must somehow prevent a group of post WW II Nazis hiding in the Hartz mountains from successfully making an atomic bomb as they plan to use the weapon on large Allied cities to help the Germans again rise to power. The two good agents find themselves entangled with beautiful German spies, but this does not keep them from fulfilling their mission just before the evil Germans are to bomb Paris. Interestingly, the Federation of American Scientists did not approve of the movie's use of the bomb.
