Dr. Craig Bakus leads the Roebling Clipper as it heads toward the moon carrying civilian passengers. Everything seems to be running smoothly as the ship exits the Earth's atmosphere, when a sudden spike in solar radiation causes the Roebling Clipper to go into overdrive, hurtling it toward the moon and endangering the lives of everyone on board.

Back on Earth, pandemonium ensues when there's no more electronic communication. Meanwhile, in space, the Roebling Clipper is now rushing toward the sun. Can Craig Bakus and the passengers steer the vessel away before the sun's rays incinerate it?
