Threshold is a science fiction drama television series that first aired on CBS in September 2005. Produced by Brannon Braga (best known for his work on the Star Trek franchise), David Goyer (best known for films such as Blade and Batman Begins) and David Heyman, the series focuses on a secret government project investigating the first contact with an extraterrestrial species. This series was often referred to as a reverse X-Files, with the main characters of the series seeking to cover-up the truth about first-contact instead of uncovering the conspiracy.
