The Nemesis is ordered to sail up the Amazon River in search of a secret Nazi base that has been hidden deep in the Amazon rainforest. Built in the latter part of World War II, the base was designed for the children of the Lebensborn, Hitler’s master race, to hide them and protect them until the Third Reich could rise up from the ashes. Further, top secret satellite reconnaissance points to this mysterious region as being the place where radio signals won’t work and the source of numerous UFO sightings by the U.S. Navy and others.
