A bombshell is dropped in US Congress that makes a lot of people start thinking about UFOs, now called UAP, differently. Danielle O’Neal tries to understand the implications of everything she’s heard and grapples with the unanswered questions.  

Despite an alarming coincidence being uncovered in the government’s UFO files, a young intelligence officer recommends the files are closed and investigations shut down. Decades on, while the U.S. is taking a serious look at unexplained aerial phenomena (UAP) the legacy of that decision has kept UFOs in the sneered-at periphery in Australia.  

The Tully phenomena spreads, with unexplained circles starting to crop up around the country. Reports of them all are filed away by the RAAF in the secret UFO files. But, one young UFO researcher is determined to get access to those files and see just what they hold.  

Hoards of people descend on the Pennisi property to take a look at this ‘saucer nest’, sending the family running for cover. Turns out, in the years to come that would be the least of their worries.
