"My name is Molly Caffrey, and I work for the Federal Government. I deal in worst case scenarios, the unthinkable. On September 16th, 2005, the unthinkable happened.
"An extraterrestrial object appeared off the bow of a naval freighter. The entire crew was exposed to a high frequency signal. Some died instantly. Others began to change. They are now stronger, more resilient. They dream of alien landscapes. And they are driven by the impulse to infect others.
"Several of the crewmen are now loose in the United States. They will strike anytime, anyplace, anyone. Their goal: to turn us into them. But I have a plan to stop them. That plan is called ... Threshold."
Those are the opening words of each episode of sci-fi drama Threshold, which first aired on CBS on 16 September, 2005.
Threshold is a suspenseful drama about a team of experts who are assembled when the U.S. Navy makes a chilling discovery: an extra terrestrial craft has landed in the mid-Atlantic ocean.
Dr. Molly Anne Caffrey is a government contingency analyst whose job is to devise response plans for worst-case scenarios. In a single instant, her life changes when one of those plans - Threshold - is activated by Deputy National Security Advisor, J.T. Baylock.
Armed only with her hypothetical strategy to address the appearance of aliens on Earth, Caffrey now finds herself thrust in the midst of a global crisis.
She hand-picks a team of eclectic specialists to prepare for first contact: Dr. Nigel Fenway, a disillusioned NASA microbiologist; Lucas Pegg, a brilliant but neurotic physicist; Arthur Ramsey, an expert in languages and mathematics; and Cavennaugh, a highly trained covert operative with a mysterious past.
Together, they decipher the intention of the craft, the fate of the ship's crew and begin preparations for the possibility of a crisis situation - an alien invasion.
There are 13 episodes in the series, which was cancelled in the US on 23 November, 2005. Only nine episodes were shown in America, but South Africans got the full package of thirteen.
Threshold will be released on DVD on 22 August, 2006.
