Movie Summary: [Action/Adventure]

    When Colorado astronomer Dr. Lily McKee discovers that an approaching comet has dislodged several giant asteroids, propelling them on a crash course with Earth, she contacts Federal Emergency Management Agency director Jack Wallach to help handle the impending crisis. Jack, as well as local firemen, works round the clock to evacuate the city and rescue victims. Meanwhile, Lily realizes that an even more devastating fragment of the comet is headed toward Earth. An attempt to divert the asteroid by firing three airborne lasers creates a hellish meteor shower--with a dangerously large asteroid headed directly for Dallas. From the producer of "Predator" and "Daylight."
