At first thought to be meteors, the United States military suspect that a number of enormous alien spacecraft are on a collision course with Earth. After attempts to communicate with the aliens go nowhere, David Levinson, an ex-scientist turned cable technician, discovers that the aliens are going to attack major points around the globe in less than a day. On July 3rd, the aliens all but obliterate New York, Los Angeles, and Washington. Survivors set out towards Area 51, a strange government testing ground where it is rumoured the military has a captured alien spacecraft of their own. The survivors devise a plan to fight back against the killing aliens, and July 4th becomes the day humanity will fight for its freedom." -- Provided by the Publisher.
