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.
Agents Mulder and Scully return after 13 years to investigate a government conspiracy at the behest of a popular web-TV-show host, who introduces them to a woman who claims she's an alien abductee and shares startling news with them.
