As the Cold War deepens and the new political threats loom for PROJECT BLUE BOOK, Dr. J. Allen Hynek (Aidan Gillen) and Captain Michael Quinn (Michael Malarkey) must delve further down the UFO conspiracy rabbit hole in their dangerous quest for the truth. Soon, cover-ups from the past (including at Roswell) collide with new UFO cases in the present (including at Area 51), forcing our duo to not only question the multi-faceted layers to a broadening global conspiracy, but the very nature and origin of UFOs themselves in an increasingly unstable world.
