the main plot is super sci-fi-y but.... can't really sum it up in short.
the more i say the more I'll have to say. so do not think of the show this way but here are the main ideas. a guy named Mulder (last name) has his sister abducted
(he believs by aliens) when he is 12, becomes a profiler in the FBI and find "the X-Files" as series of cases that have to do with alien and paranormal investagations. he picks up where it was left off, motivated to find his sister and the truth.
