The X-Files is an American science fiction horror drama television series that recounted 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.
Two FBI agents, Fox Mulder the believer and Dana Scully the skeptic, investigate the strange and unexplained while hidden forces work to impede their efforts.
