Director James Fox turns his camera on people whose careers gave them credibility to lose: military officers, commercial pilots, police, and government officials who each say they watched something they cannot explain. The film gathers first-hand testimony from witnesses to some of the most cited UFO cases of the twentieth century, including the 1997 Phoenix Lights, watched by thousands over Arizona, and the 1986 Japan Air Lines incident, in which a pilot reported a craft pacing his aircraft over Alaska for nearly an hour while air traffic control tracked it on radar. Fox lets the witnesses talk at length, on camera, often visibly uneasy about attaching their names and reputations to what they saw. Retired generals and commercial airline captains appear alongside radar data and archival news coverage from the time of each sighting. The film does not chase theories about what the objects were; its case rests entirely on the credibility of the people describing them, and on the fact that so many of them, independently, describe the same kind of thing.
