In 2008 in Stephenville, Texas a local pilot sees lights in the sky over his ranch coming from something huge. He is not alone: hundreds of people saw the craft, and a local reporter makes it her life's work to tell their stories. From this classic encounter we head back several decades to the beginning of the UFO phenomenon in America and the launch of Project Blue Book to study the country's growing "UFO problem".

Project Blue Book and the investigation into UFOs closes. There is no evidence that mysterious objects represent any threat to U.S. national security. But harrowing incidents of UFO sightings continue and the unexplained malfunction of U.S. nuclear missiles after an incursion leave the U.S. defenseless. Three former Air Force officers, who served at nuclear weapons bases in the late 1960s, break two decades of silence to tell their story.

From a 1986 sighting over Alaska by Japanese Airline pilots, to a 1997 UAP sighting over Phoenix Arizona and a flying disc over the Chicago O'Hare airport in 2008, hundreds of witnesses come forward without any official feedback from the US government. Years later, many of the pilots and government officials, who witnessed these sightings, come together for the first time to share their story in a 2007 press conference.
