Meanwhile, the Logans encounter an alien disguised as Michael Jackson, and U.S. president Baxter Harris personally visits the farm to investigate the crop circles.
When Cindy asks about how this relates to the aliens, the Architect speculates that Tabitha is summoning them to aid her in destroying humanity.
Returning home, Cindy discovers Cody is missing, the news has been broadcasting the cursed tape for hours, and there have been various sightings of aliens around the world.
Tom sends Cindy, Sue, and Cody into the basement for safety, as he, George and Mahalik go outside to fight the aliens with help from President Harris and the Secret Service.
