The most spectacular meteor shower in 10,000 years results in a direct hit to the moon, leaving it on a collision course with the Earth. A small group of international astronauts, scientists and soldiers band together in a race against time to save humanity, in the thrilling limited ABC series Impact, airing SUNDAY, JUNE 21 and SUNDAY, JUNE 28 (9:00-11:00 p.m., ET both nights), on the ABC Television Network. David James Elliott (Close to Home, JAG) Natasha Henstridge (Eli Stone, Species), Steven Culp (Desperate Housewives, ER) and Oscar and Emmy-nominated James Cromwell (W, L.A.

Their fears are realized when the anomalies increase to the point where the effect of gravity is being manipulated by increased electromagnetic surges coming from the moon. People, cars and other objects are rendered momentarily weightless in random, isolated areas around the globe. Alex, Maddie, Roland and the rest of their team soon discover something far worse -- the moon's new orbit has put it on a collision course with Earth! The world now has 39 days to stop the moon or Earth, or all of mankind will perish. After a failed attempt by th...
