Botanist Shermeen Williams is visited by the disembodied spirit of Vindrus, who tells her he's a being from an antimatter universe who's people are facing extinction if they do not cross over to the universe of matter. He tells her to bring a portable nuclear generator to a temple on the planet Sunim, to power the machine that will allow his people to enter this universe. What he has neglected to mention, is the fact that for every one of his people that crosses over, one must be sent from this universe to his. Vindrus plans to use the people of Alpha to maintain the balance.
