It's the sci-fi series that almost all modern genre shows take at least a few cues from. Special Agents Mulder and Scully take on the weirdest, most unbelieveable cases and try to unravel a massive government conspiracy theory along the way. The series has gone to the big screen twice: first, in 1998, then a 2008 sequel The X-Files: I Want To Believe.
