On 13 March, 1997, a string of fiery globes were seen over Arizona, but earlier that night some eyewitnesses saw something more shocking - a huge boomerang-shaped object.

The team recovers physicist James McDonald's long lost research. Over 20 years, he interviewed more than 500 witnesses of UFOs and unearthed revealing government documents.

On December 29, 1980, Betty Cash, Vickie Landrum and Colby Landrum took a drive that would become a life-changing nightmare. At approximately 9 p.m., driving through the Piney Woods in Texas, they observed a huge diamond-shaped object flying low above the isolated road, expelling flame and emitting significant heat. That night, all three experienced horrible physical symptoms: nausea, vomiting, diarrhea, weakness, and burning sensations all over their bodies. The team reopens this and other famous cases of alleged alien effects to determine if UFOs are leaving behind more than just stories of sightings.
