Earth and moon are on a collision course in the thrilling limited series Impact starring David James Elliott and Natasha Henstridge, June 21 & 28 at 9 PM on ABC.

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.

Elliott (Close to Home, Jag), Henstridge (Eli Stone, Species), Steven Culp (Desperate Housewives, ER) and Oscar and Emmy-nominated James Cromwell (W, L.A. Confidential, Babe) are among the stars of the international cast.

The world watches as a large meteor shower streaks across the skies. Hidden in the meteor field is a brown dwarf , a dead star. It smashes into the moon in a tremendous explosion of rock and debris. Fragments of the moon itself penetrate Earth’s atmosphere and make impact. Even though initial damage is minimal, nerves are frayed throughout the planet. Experts quickly conclude there will be no lasting ramifications. Then strange anomalies begin to manifest themselves on Earth. It starts small – cell phone disruptions, unusual static charges and odd tidal behavior. The world’s leading scientists, including Alex Kittner (Elliott), Maddie Rhodes (Henstridge) and Roland Emerson (Benjamin Sandler), begin piecing together evidence that suggests that the moon and its orbit may have been permanently altered. 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 the United States to destroy the moon, the scientific team works together to mount an international mission to the moon. Alex, whose children and father-in-law (Cromwell) have gone missing, is torn as he must join Roland on the mission to the moon. It’s a race against time as the two celestial bodies are drawn closer and closer to impact.
