Episode Overview
As preparations for an alien assault ramp up, ORCA begins evacuating all non-essential staff. Louis alerts agent Shelby that Hauser has excluded Ilona from the evacuation list, leading Praxis to uncover that both Ilona and her mother are aliens. Louis also manages to get himself removed from the list, prompting Brett and Cass to decide to stay behind as well. Believing that Malakat and his commandos have evacuated the pyramid as promised, Jason, Neri, and Mera are soon captured when the commandos reemerge. As a nuclear torpedo launch aimed at the pyramid is detected, chaos ensues. ORCA successfully halts the launch, but Helen reveals she acted on orders from "a higher power." With the launch stopped, Shersheba and Malakat return to activate the pyramid with the golden ankh, and Malakat's first command is to start melting the polar ice caps.
