Plot Synopsis

Executive produced and host by Josh Gates, EXPEDITION UNKNOWN: HUNT FOR EXTRATERRESTRIALS is a four-part special event series that follows Josh as he embarks on a worldwide expedition searching for evidence of extraterrestrial life. It is mankind's eternal question: are we alone in the universe? Adventurer and explorer Josh Gates sets off on a 50,000-mile, multi-continent quest to find the answer. Gates' out-of-this-world mission takes him on an epic journey across North America, South America, Africa and Europe, searching for evidence of life beyond our planet and the truth behind longstanding extraterrestrial legends. Gates gains exclusive access to locations that may offer extraterrestrial evidence. He explores ancient signs of aliens in remote caves on Easter Island, tests futuristic deep-space telescopes in Chile's Atacama Desert and hunts for meteorite fragments at a crash site in the wilderness of Zimbabwe. Gates also interviews eyewitnesses who claim to have irrefutable evidence of UFOs, goes behind the scenes at NASA's mission control in Texas to connect with astronauts in orbit, travels to the 70th anniversary celebration of the Roswell Incident in New Mexico and hears the very latest from scientists who are bringing us closer than ever to answers.
