On July 2, a giant alien mothership enters orbit around Earth and deploys several dozen saucer-shaped 'destroyer' spacecraft that quickly lay waste to major cities around the planet. On July 3, the United States conducts a coordinated counterattack that fails. On July 4, a plan is devised to gain access to the interior of the alien mothership in space, in order to plant a nuclear missile.
lots of mass panic and yelling/screaming as major cities are attacked. there is also panic in the autopsy room where they are dissecting an alien and it wakes up
Jimmy jokes about kissing b**t. A hillbilly teases Russel by asking him if the aliens probed" him. Jewel is a stripper. A teenager asks his girlfriend if she doesn't want to die a virgin.
Air Force II is knocked out of the sky. Several fighter jets and flying saucers are shot down. Russel deliberately crashes his plane into a flying saucer's city-buster cannon.
Several cities and landmarks (including the White House) are blown to kingdom come by an alien death cannon -- something that was a massive selling point in the film's marketing. Later in the film, the US military retaliate with their own nuclear strike that ultimately fails. SPOILER: The climax ends with a nuclear bomb being detonated within an alien mothership.
