The sky is literally falling in this thriller as one of the nation's leading astronomers, Madison Kelsey believes she is tracking a huge rogue asteroid rocketing toward earth. However, she can't get anyone in authority to take her seriously because the mysterious asteroid exists only in the mathematical calculations of her computer program and it's not yet visible. With only hours remaining until probable impact, Madison enlists the aid of discredited former Air-Force Colonel, Richard Donovan. (imdb)
