The mysteries of Australia may just hold the answers mankind has been searching for millennium to find. When Doctor James Hay, a university scientist who studies the paranormal mysteries in Australia, finds an obelisk of carved volcanic rock on sacred Aboriginal land in northern Queensland, he realizes it may hold the answers he's been seeking. A respected elder of the Aboriginal people instructs James to take up the gauntlet and follow his heart.
Along with his old friend and award-winning writer Spencer, Samantha Louis, her cameraman, and two of James' Aboriginal students, James embarks on a life-changing quest for the truth.
