Pushed by Rasputin, who promises him the power of the Vril, Hitler orders the super Zeppelin through a portal to another world, which opens in the skies above Spitsbergen. Convinced that this new world is actually that of the ancient Aryan Atlanteans, Hitler seeks to claim their power for himself and his men, but Rasputin does not warn them of the dangers they will face... As a terrible fight, against ancient beasts unfolds in the other world, Russian and French forces prepare to take control of Spitsbergen, and ambush the Zeppelin on its return.
