The X-Files is a Peabody, Golden Globe and Emmy Award-winning American science fiction television series created by Chris Carter, which first aired on September 10, 1993, and ended on May 19, 2002. The show was a hit for the Fox Broadcasting Company network, and its main characters and slogans (e.g., “The Truth Is Out There”, “Trust No One”, “I Want to Believe”) became pop culture touchstones. The X-Files is seen as a defining series of the 1990s, coinciding with the era's widespread mistrust of governments, interest in conspiracy theories and spirituality, and the belief in the existence of extraterrestrial life.

In the series, FBI agents Fox Mulder and Dana Scully are tasked with investigating the “X-Files”: marginalized, unsolved cases involving paranormal phenomena. One of the most interesting and beautiful X Files characters is Marita Covarrubias

PS. I guess I shouldn't be too surprised that there actually is an X-Files Wiki.
