The year is 1917 - war engulfed the earth. Billions were killed at the hands of unprecedented technology in the name of fanaticism. Yet all previous atrocities were as preambles to an even greater, unforeseeable catastrophe. When on the 15th April, a host of aliens descended from war-torn skies and opened fire indiscriminately on soldier and civilian alike, the foundations of the world were shaken and mankind would face his darkest hour. Against such a terrifying, overwhelming foe, the scrambling, exhausted nations of Earth had no choice but to put aside their old grudges and fight side by side if they wanted to avert total extinction - or worse. Still, courage and unity were not enough to match the sheer power of a species so advanced that the very cosmosproved no obstacle to them.

Based not only on existing aeronautical technology but also on fragments of alien wrecks from the recent battlefields, this new invention is capable of prolonged atmospheric flight as well as deep, interstellar travel. Finding no pilots left in any condition – bodily or mentally – to take the pilot seat, the brave doctor dons the helmet herself and takes the Red Beezlebub on her virgin flight, to the battlefields of Verdun. Her target: the hessmaster, the new, self - crowned king of humanity. A usurper and abomination. Fuel led by gasoline and hatred, her Valkyrie's flight will end either in victory or glorious death. Little did she know that he himself is only a piece on the real player's board, and she is watching Brunhild's every move with greedy, leering eyes...
