In Roswell, New Mexico, the epicenter of UFO activity, the team sees a video of an alleged UFO crash and investigates the site of the incident.

Since 1993, residents in the Phoenix area have reported sightings of mammoth wedge-shaped objects, and the evidence includes a convincing video.

The team travels to Florida to investigate numerous sightings of objects that appeared to follow the Space Shuttle as it left the launch pad.
