Meet Mulder and Scully, FBI. The agency maverick and the female agent assigned to keep him in line.

Their job: investigate the eeriest unsolved mysteries in modern America, from pyro-psychics to death row demonics, from rampaging Sasquatches to alien invasions. The cases the Bureau wants handled quietly, but quickly, before the public finds out what's "really" out there. And panics. The cases filed under "X."
