Flying saucers, big-eyed humanoids, night abductions and mysterious signals from space - all these UFOs are the subject of heated debate and crazy beliefs. But where UFOs appeared, you should also expect people in black. British writer and paranormal investigator Mark Pilkington decided to find out what the secret agents are doing, who supposedly know where flying saucers come from and where aliens are hiding, but do everything to keep ordinary people in the dark. What lies behind the image of a silent agent covering his tracks? Is there a connection between UFO visits and the activities of intelligence agencies? And if so, then what are they hiding from us? “Ufologists in Plainclothes” is a participatory study of ufomania, which swept the planet in the middle of the last century and has not subsided to this day. At a convention of ufologists and at a US military base, in the deserts of Nevada and the slums of Detroit, Pilkington talks with a variety of people, from enthusiasts convinced of the existence of aliens to evasive special agents, delving deeply into the history of supposed contacts with extraterrestrial life and coming to paradoxical conclusions that will change your idea not only about aliens, but also about people.
