Mulder faces an FBI review panel to justify reopening The X-Files. Without proof, the panel finds his report of man-aided alien global domination and the agents' Antarctic adventure "essentially unintelligible". But the proof/truth is out there, in a hideous form that attacks with deadly sharp claws. A covert assist from Skinner puts them on the trail, but they're unauthorized, and they're not alone: the Cigarette-Smoking Man is also after the being, and he has a decided edge after drafting some help.
