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.

Cultured Mario and outlaw Lucien, twins separated at birth, join forces to avenge their parents' death at the hands of evil Colonna. Because each feels all the same sensations experienced by the other, swordplay is difficult for them. Worse yet, raised very differently, they struggle to find common ground between their conflicting personalities. But to defeat their enemy, the two will have to overcome the obstacles and work as a team.

The narrator's voice tells of John Dough, who wakes up after a late-night party and prepares to go to work. However, a few interruptions, including thinking for a moment that he sees a woman's body in his bed, having his car key not work, and thinking he hears his mother calling, delay his departure from home by almost a minute. When tragedy strikes close by, John revisits the morning's events. A phone call from his brother in Chicago confirms how odd this morning is. Did John experience telepathy or was it all coincidence? If radio waves can carry a communication, why not a mother's love?
