A clandestine group of college professors and graduate students, operating under a NASA grant in a secret complex hidden beneath a college campus, is given the challenging task-the task to gradually acclimate Earth to the existence of aliens who've been observing the planet and its inhabitants for decades. Events take an unexpected turn, however; and when the pieces to the puzzle fall into place, a sinister secret is discovered. The resulting race to save Earth takes an ordinary young man on an extraordinary journey across the galaxy.
