Mirage Men examines evidence of a conspiracy by the United States military to fabricate UFO folklore over decades in order to deflect attention away from classified military projects. The film profiles a retired Special Agent, Richard Doty, who worked for the United States Department of the Air Force Office of Special Investigations, and the United States Air Force Office of Special Investigation, and speaks about his role in special operations that targeted both individual people, and the public at large for many years. The film also weaves in the viewpoints of others, either in the sphere of the myths, or working to uncover their origins.
