Staff Sergeant Winthrop Carter has just been drafted into the Nightstalkers�an elite group of soldiers that... Actually, he�s not quite sure what they do. Born from the Area 51 initiative, the Nightstalkers defy sanity and decorum and include among their ranks Moms, a Black Ops trainee too extreme for Special Forces; Doc, a scientific crackpot; Roland, the weapons enthusiast; and Mac, a contemporary MacGyver. All of them take their orders from the elusive Ms. Jones, who everyone claims is just a hologram. Those orders include tracking down and sealing tears in our reality that are releasing interdimensional beings known only as Fireflies� creatures that take control of both living and inanimate matter in order to unleash wanton destruction. Just as Carter is settling in, a rogue scientist triggers a fresh invasion of Fireflies that swarm a swanky gated community. Now it�s up to Carter and his new teammates to neutralize the threat while figuring out who�s behind the breach.
