The exploits of FBI Special Agents Fox Mulder and Dana Scully who investigate X-Files: marginalized, unsolved cases involving paranormal phenomena. Mulder believes in the existence of aliens and the paranormal while Scully, a skeptic, is assigned to make scientific analyses of Mulder's discoveries that debunk Mulder's work and thus return him to mainstream cases.
When the bodies of a couple who have been missing for less than a week are discovered to have been reduced to bone, Mulder suggests that recent paranormal phenomena in the area may have caused the accelerated decomposition.
