Dr. Paul Sorenson, a noted astronomer, believes that an approaching comet will collide with earth based on his study of an ancient civilization's prophetic timeline. Frustrated by his inability to convince other scientists of the threat, Sorenson and a band of followers take over a nuclear missile silo. The FBI enlists the help of Sorenson's daughter Katherine, who is also a respected scientist, with the hope she can convince her father to surrender the missile silo. Katherine's research supports her father's thesis. She enlists the help of Paul, an FBI agent assigned to keep her under guard, in her quest to convince the scientific community of the imminent threat to the planet. Written by Dennis Lewis

This one hour program tells the story of a team of scientists who believe and intend to prove that the world's largest environmental disaster, the asteroid, is entirely possible. It shot from a hot white sky with absolutely no warning. On Friday, June 14, 2002, an asteroid the size of a football field made one of the closest ever recorded approaches to Earth. Traveling at more than 10km/second, it brushed past Earth completely unseen, at a distance of 120,000km, less than a third of the distance to the Moon. Had it hit the Earth it could have devastation on a scale similar to that of the asteroid impact in Tunguska, Siberia in 1908, when 2000 square km of forest were flattened in a matter of seconds. Had that chunk of space debris hit Moscow or Hong Kong instead, the loss of life would have been staggering. This one hour program tells the story of a multi-national team of scientists who believe and intend to prove that the world's largest environmental disaster is entirely possible.
