A "flap" is defined as a series of sightings by multiple witnesses over numerous days. And they're rare. That's why the MUFON team is rushing to investigate this July, 2008 flap. Most witnesses in Bucks County, Pennsylvania, have little to offer but anecdotal testimony. However, the team discovers two witnesses who had multiple sightings and appear to have scientific corroboration for their claims. But scientific disagreements and government stonewalling, obscure what was thought to be an unambiguous investigation.
MUFON - the Mutual UFO Network - using the tools of science, psychology and law enforcement, investigate a case that's grown far beyond its initial UFO sighting. Chris Bledsoe, the key witness in the event, undergoes hypnosis and declares he was abducted. The investigators try to separate fact from fiction when they bring in a psychologist. The tests rule out mental illness. Several other witnesses of the alleged sighting are tracked down and confirm much of Chris' story. But this one-in-a-million case stumbles when Bledsoe takes a lie detector test.
The search for UFOs goes international as MUFON sets off for Mexico. Newspaper reports and videos of a UFO flying over the rural town of Mezcala triggers the deployment of an investigative team in the summer of 2008. During a stop over in Mexico City, the team investigates a man who has videotaped hundreds of UFOs flying over the city. But as the team prepares to leave for Mezcala, the investigation gets diverted when remarkable daytime photos of a UFO hovering in the sky emerge. The team travels to meet with the photographer as an expert in the States analyzes the photos. The encounter with the photographer comes to a head when suspicions about the photos arise. Finally, the team arrives in Mezcala only to discover the story is changing before their eyes.
