With the help of some very close friends in the nathalis intelligence services, Commander Arthwal's investigation into the mystery surrounding the deaths of Alarwyn's parents leads to a revelation that could rock the very foundations of the nathalis political system. Unfortunately, it also leaves him in a position where he must put his career on the line in order to give Alarwyn the justice she deserves.
Also, the hybrids are aging rapidly, and time is running out. In his desperation to save their lives, the colonel turns to Derek and Jarrod for help. Their plan to get the hybrids off the base however hits a snag when an administrator named Wilcox starts throwing some nasty accusations at the colonel, leaving them with no other choice but to expose themselves if they're going to save the lives of both the hybrids, and the colonel as well.
Finally, when Tina, Sarah, and Jarrod kidnap Heather from the house in Scotland so they can take her out on a little adventure to a random dimension, they thought they were going to end up someplace exotic, or maybe even run into yet another strange species that they'd get to document and study. Unfortunately, the random dimension they happened to choose didn't provide them with any of that. Instead, they find themselves in a parallel dimension, standing in the living room of their old house while they try to have a conversation with a parallel version of Patricia, who has no idea who any of them even are.
