Maia is sick, and Diana brings her into NTAC, where a 4400 terrorist is marking the date of Jordan Collier's birthday by placing a device that makes the males go savage, bringing on a lockdown of the facility. Meanwhile, Kyle's life takes a more normal turn with him going back to college and the start of a romantic relationship. Also, Lily begins to doubt that the 4400 Center's interest in Isabelle is trustworthy. And after a less than perfect interview with the media, Shawn tries to make changes at the 4400 Center to make it seem less like a cult to the general public.
