"Adam and Eve of the year 2024! Only they could repopulate the world!"
In 1960, a pilot testing an experimental rocket powered aircraft accidentally flies into the future and finds himself in a sealed city whose people suspect he is a spy from outside their walls, but who want to keep him to procreate with the ruler's daughter because the majority of the inhabitants are sterile.
