A low earth orbit space station is in the middle of a repair mission with the space shuttle when an unforeseen
meteor shower obliterates them both. This sudden event sends fireballs hurtling to Earth and scientists scurrying
to telescopes. An amateur astronomer is the first to spy a gigantic fireball headed towards the planet and
notifies NASA. Turner informs the president of the asteroid and describes it as being "the size of Texas," a
planet-killer. With eighteen days to impact, NASA frantically tries to find a solution but ends up turning to an
outside contractor. Harry Stamper and his team of oilmen are called upon to save the planet as only they can.
