I actually didn't see the 1st movie until it was on HBO 2 yrs later LOL. Was actually entertaining. Here's brief plot summary based off the novelization of the movie being released shortly before the movie premiers this Summer.
THE X-FILES 2008 MOVIE NOVELIZATION MMPB
by Max Allan Collins
Mulder and Scully are back in the thrilling novelization of the summer 2008 blockbuster movie based on the classic X-Files TV show! When a group of women are abducted in the wintry hills of rural Virginia, the only clues to their disappearance are the grotesque human remains that begin to turn up in snow banks along the highway. With officials desperate for any lead, a disgraced priest's questionable "visions" send local police on a wild goose chase and straight to a bizarre secret medical experiment that may or may not be connected to the women's disappearance. It's a case right out of The X-Files. But the FBI closed down its investigations into the paranormal years ago. And the best team for the job is ex-agents Fox Mulder and Dr. Dana Scully, who have no desire to revisit their dark past. Still, the truth of these horrific crimes is out there somewhere...and it will take Mulder and Scully to find it!
