Many centuries ago, an alien race known as the Nar were able to recreate human beings from genetic code, broadcast from earth into outer space by a beleaguered humanity. Although the Nar are kind and benevolent masters to the humans, discontent leads the humans to rebel, and the Nar realize that they do not yet fully understand their rebellious creations. They allow a group of humans to travel millions of light years through the galaxy, in order to discover what has happened to the original occupants of planet earth. However, none of the human participants of the expedition are prepared for what awaits them at the completion of their journey…
The Lunar Observatory on earth is picking up a very strange and unidentifiable signal from the direction of Cygnus. When the meaning of this signal is finally understood, it clearly spells disaster for earth. An immense object is rushing towards the Solar System, traveling nearly at the speed of light, its intense nuclear radiation sure to kill all life on earth within months. As it moves close the humans can discern that it is an enormous convoy of some sort, nearly as large as a planet. And there is nothing anyone can do to divert such an enormous alien object. Then, unexpectedly, the object changes course and heads toward the dead planet of Jupiter but what could an enormous alien convoy want with such a useless planet?
