Overview
The series stars Carla Gugino as Dr. Molly Caffrey, a high-level government crisis management consultant from the Blackwood Institute whose job is to create contingency plans for use in emergencies ranging from natural disasters to nuclear war. In order to have "all bases covered", one of her plans, code-named Threshold, is developed for dealing with the unlikely eventuality of first contact with aliens. One night, the crew of a U.S. naval vessel encounters a UFO. Many crew members subsequently die horribly, but some escape. After the ship is discovered with dead crew members and a videotape of the encounter, the Threshold protocol is activated.
Caffrey's Threshold plan calls for the formation of a secret government task force known as the Red Team. As a result, several top scientists are seconded: Dr. Nigel Fenway (Brent Spiner), an individualistic NASA-employed microbiologist; Lucas Pegg (Rob Benedict), a somewhat unsure-of-himself aerospace engineer on the eve of his marriage, and Arthur Ramsey (Peter Dinklage), a mathematics and linguistics genius with a penchant for unpredictability, alcohol and women. Caffrey's government liaison is Deputy National Security Advisor J.T. Baylock (Charles S. Dutton), while freelance paramilitary operative Sean Cavennaugh (Brian Van Holt) serves as the "muscle" of the group (and apparent potential love interest for Caffrey). Daphne Larson (Catherine Bell) was added to the team in the episode "Outbreak". Caffrey's team works under absolute secrecy, their activities not even known to the Vice-President, or the Joint Chiefs of Staff.
Threshold learns that the aliens are attempting to rewrite the DNA of the human race using, in part, an audio signal that somehow alters some people's body chemistry in such a way that they become alien themselves. Central to all this is a fractal triskelion pattern that keeps appearing – in electronic signals, blood, and even the pattern made by city lights. Its significance has yet to be revealed, though Arthur Ramsey interpreted it as representing a DNA pattern in a triple helix formation (like the alien DNA).
The episodes focus on Caffrey and her team as they learn more about the signal, the fractal pattern, and the aliens. Often, their work requires them to impersonate different U.S. Government agencies. Compounding the situation, Caffrey, Cavennaugh and Pegg were exposed to a small part of the signal, which while not (as yet) infecting them, has nonetheless altered their brains, causing the trio to have bizarre, linked dreams, and also receive messages from the aliens with Caffrey, in particular, experiencing frightening, often violent hallucinations. Individuals experiencing these visions have been referred to as "dreamers" by the Threshold Red Team.
An ongoing subplot of the series is the emotional impact Threshold has on Caffrey herself, as she is required to make life-and-death decisions on an almost daily basis. The impact on other members of her team is also explored.
In one of the unbroadcast episodes, one of the hybrids reveals that the aliens plan to save humankind by changing their DNA and the surface of the earth. This is because millennia ago, far out in space, two neutron stars collided, creating a gamma ray burst - the radiation of which is heading for Earth and will, when it arrives in six years, end all life on the surface of the planet. Because the revelation came from a hybrid, this explanation is considered suspect and that the hybrid's sole intention is to slow the Threshold program. In Episode 11, which was unaired in the US, NASA sends a Top Secret letter to Caffrey confirming the alien allegation about the cosmic radiation impact on Earth in 6 years. The text of that letter is below:
Dear Dr. Molly Anne Cafrey
In reply to your request for information at the following coordinates
Eight hours right ascension, thirty four degrees south declination
It has been confirmed that approximately 400,000 years ago two neutron stars collided at these coordinates, and the cosmic radiation that resulted from this collision is expected to affect the Earth in approximately 6 years.
Cosmic radiation is a collection of many types of radiation from many different types of sources. When people speak simply of 'cosmic radiation' they are usually referring specifically to the cosmic microwave background radiation. This consists of very, very low energy photons whose spectrum is peaked in the microwave region and which are remnants from the time when the Universe was only about 200,000 years old. There are also very old remnant neutrinos in the cosmic radiations.
When these particles make it to earth, it will interact with our atmosphere. Our atmosphere is able to reflect small amounts of these particles and act as a 'radiation shield.' The amount of particles that will enter our atmosphere in 6 years as a result of this collision will most likely be more than our atmosphere will be able to protect us from. The Earth will be completely destroyed and all human life will be extinguished.
We thank you for your concern and interest and hope this information has been of help to you.
According to writer Brannon Braga on the 2006 DVD release, word that production of the series was being terminated was received midway through shooting of the episode "Alienville". The ending of the episode was changed to show Molly having a dream conversation with an alien-human baby (who had been born in the episode, but appeared in the dream as a nine-year-old boy). The boy tells Molly that her Threshold plan will eventually succeed in stopping the alien invasion (the age of the boy implies it'll happen within nine years), but that she would herself ('not be there') before this happens.
Threshold was the first CBS television series to utilize "streaming video" to re-air new episodes after the original airdate. Each new episode was posted on the CBS website five days after its original airdate and remained accessible there for three days. Nancy Tellem, president of the CBS Paramount Network Television Entertainment Group, stated that "the goal here is to recruit new viewers to Threshold, help existing viewers catch up if they've missed some episodes and drive more traffic to CBS.com." Survivor and The Amazing Race both utilized a similar method for post-show interviews and discussions. The following television season (2006–07) CBS incorporated this concept into a streaming video area on their website called Innertube. The "behind the scenes" video clips for Threshold are still posted on the site under the "past broadcast shows" tab.
