The team investigates an alarming pattern of UFOs allegedly appearing near US. Air Force bases that house nuclear weapons, and nuclear-powered US warships. A new eyewitness account suggests these craft have an incredible ability. Connections to an historic sighting where a UFO allegedly interfered with a U.S. nuclear weapon are explored. Elizondo briefs former U.S. Senator Harry Reid who offers a stunning theory about UFOs.

In an international UFO hotspot, Lue Elizondo uncovers exclusive video of a glowing orb recorded recently by an airline pilot at 35,000 feet. He investigates possible connections to secret technology related to the USSR, plus a shocking aerial battle between a jet fighter pilot and a UFO. Local people reveal an ancient connection, as high-ranking officials drop a Project Blue Book bombshell. The planetary threat of UFOs is explored.

U.S. airline pilots are reporting near mid-air collisions with UFOs. Elizondo hears a never-before-told account from a major legacy airline pilot whose report of a glowing orange sphere while in the cockpit over Arizona is backed up by photo evidence. Elizondo speaks to another veteran commercial pilot, also former military, with a harrowing story of an unidentified object apparently tracking his jetliner. In both cases, the pilots feared a mid-air collision that would have killed hundreds of passengers.

In 2017, Tom Delonge and Lue Elizondo helped engineer the release of 3 videos captured by U.S Navy fighter pilots of "Tic-Tac-UFOs." The strange objects had no wings and were capable of seemingly impossible maneuvers. These videos impelled the U.S. Navy to acknowledge these unidentified objects exist. Now, new eyewitnesses radically expand what's known about Tic Tacs and could provide clues to the mysterious crafts' origin. Evidence of a possible U.S government cover-up is examined.

Lue Elizondo calls on a new technology to analyze a series of UFO videos all recorded in 2019--a year that featured a huge increase in UFO sightings. While previously focusing on U.S. Military eyewitnesses, the team broadens its focus to civilian accounts. Among the cases are a series of strange formations of craft reported by civilians in Colorado. Connections to UFO sightings by the U.S. Military are explored.

When Lue Elizondo was part of the Pentagon's Advanced Aerospace Threat Identification Program (AATIP) he identified five observable characteristics of UFOs, dubbed the "five observables." But there is a so-called sixth observable Elizondo began to investigate--an invisible threat these craft may pose. On the trail of this phenomenon, he uncovers never-before-told accounts by U.S. Air Force personnel stationed at the USA's most sensitive sites.

For decades, UFOs have been the domain of science fiction and conspiracy theories. But not anymore. Over the past few years, the United States government has begun taking sightings of unknown objects by members of our military seriously, and subjecting them to further study. Featuring first-person accounts by military eyewitnesses, government insiders and UFO experts, this special offers an update to the groundbreaking Unidentified series, and traces how we got here, and what a government investigation into 144 recent sightings can tell us about what these mysterious objects are and where they come from.
