The Hunters attempt to "reprogram" a captive Regan. While the ETU work to locate their missing agent, they deal with the possibility that there could be a mole in their ranks.

A cross between gritty crime drama and sci-fi thriller, Hunters is inspired by Whitley Strieber's best-selling novel, Alien Hunter. The show is about the disappearance of a decorated FBI agent's wife, which leads him to a secret government unit assembled to hunt a group of ruthless terrorists called "Hunters" who do not come from this world.
