The series is about two FBI agents, Dana Scully (Gillian Anderson) and Fox Mulder (David Duchovny). Together, they work to find answers to strange cases. Many of these cases have to do with aliens and the paranormal.

The X-Files was a very popular show; it is the second longest running science fiction show behind Stargate SG-1. It also won awards like the Emmy Awards and the Golden Globe Awards.

Plot 
The plot of the show has to do with finding the answer to mysteries, or X-Files. Mulder believes that the answers to many of these mysteries have to do with aliens and the paranormal, while Scully believes that the answer can be found using science.  Sometimes, there are monsters that are introduced into the show.  Episodes with monsters in them are called "Monster-of-the-week" episodes.

There is a plot in the show about Mulder's sister, Samantha Mulder.  She was taken by aliens when she was little.  Mulder spends a lot of time looking for her.  In season seven, Mulder finds out that both the aliens and the government took his sister for experiments.  They wanted to make an alien-human hybrid and used Samantha as a test subject.

Mulder and Scully believe that there is a part of the government that is helping the aliens.  They find out this is true.  The part of the government that helps the aliens is called "The Syndicate."  The Syndicate helps the aliens to take over Earth.

Eventually, Mulder is taken by the aliens and is replaced in the series by John Doggett, another FBI agent.  Doggett and Scully then work together in season eight.  In season nine, Scully is replaced by Monica Reyes.
