About the title
A group of scientists led by SS officer Hans Kammler achieves major breakthroughs in antigravity. When the outcome of World War II becomes obvious, the Nazis launch several spacecraft from their Antarctic base so that the crew can establish a secret military base called Schwarze Sonne (Black Sun) on the dark side of the Moon. Germany's plan is to build a mighty armada for a decisive strike on Earth, followed by conquest of the planet. And in 2018 the Fourth Reich goes on the offensive.
