The Clampets take in the sights of the Hoover Dam by going on a helicopter tour. Then the family is dropped off in Rachel, Nevada, just before Alien Palooza 2012 is about to begin, headlined by Riley Martin of the Howard Stern show. The family learns about different aliens and find out who really killed the dinosaurs. Wilber Allen, an alien expert, invites the family to dinner at his house along with a man who can channel aliens. After dinner, they head back to area 51 with Riley and Wilber at dusk. That's when he's likely to make contact with the mother ship. Will the family make contact with aliens, or will the feds break up the party?
