The sun is rapidly burning out in the near future and will obliterate Earth. Humans race to build enormous engines that will propel the planet to a new solar system, far from the sun's fiery flares. However, the journey out into the universe is perilous, and humankind's last shot at survival will depend on a group of brave young scientists and astronauts attempting to save all from imminent destruction.

A convict using the flight as transport is now the only person Torrance can count on for help to rescue the others and keep them alive long enough for the airline to retrieve them.
