Before the black oil, the Cigarette Smoking Man, and the threat of global alien colonization, there was just Fox "Spooky" Mulder (David Duchovny) researching FBI cases with a paranormal bent in his basement office and Scully (Gillian Anderson), the skeptical agent with a degree in medicine and directions to debunk Mulder's findings. Thus, The X-Files: Season One is relatively devoid of the vast government conspiracy for which the series would become known, and serves mainly as an introduction to the show's two protagonists. Mulder, despite his reputation, is no kook; best in his class and well-known for his criminal profiling abilities, the rogue agent chose his path in hopes of finding his sister, Samantha, whom he witnessed -- or, at least, believes he witnessed -- being abducted by aliens. As eager as Mulder is to find an unearthly solution to his cases, Scully is equally determined to find an answer more consistent with the laws of science. Alone, both agents are somewhat blinded by their respective philosophies, but as partners they are able to complement one another nicely, and Scully's initial task is thrown to the wayside for a deep friendship and mutual respect that would test the boundaries of work, and ultimately the planet itself.
