The year is 1949, and science-heroes and war champions are gathering in the city of Neopolis, now under construction as a home for those with extra-human powers and talents. One of those heroes is a very young ace pilot, Steve Traynor, also known as Jetlad, fresh from the battle-torn skies of Europe, and anxious for a new life and career. With him is his former enemy combatant Leni Muller, the Sky Witch, ready to prove herself worthy of the chance given to her in Neopolis. They are hardly prepared for the challenges facing the experimental city. Science crime and unearthly gang violence has swiftly followed the heroes into this new, wide-open environment. Will their courage and skills be enough for the tasks ahead?
