Birkoff uncovers the secret location of Red Cell's base camp, which harbors the leader of Red Cell--for whom Section has been searching for almost 20 years. When the mission to extract the Cardinal goes awry, Operations decides to kill Birkoff.

On his computer, Birkoff invents a form of artificial intelligence intended to maintain the system during his upcoming two-month vacation. The computer program develops an agenda of its own and kills Section operatives.

To locate a Section communications satellite that has crashed in the southern United States, Nikita and Michael visit a strange, rural town that turns out to be Black Storm's central base.
