During the 1930s in the remote highlands of Australian Tasmania, Ruby Rose (Melita Jurisic, Mad Max: Fury Road) lives with her husband, Henry (Chris Haywood, Muriel's Wedding), and stepson, Gem (Rod Zuanic, Mad Max Beyond Thunderdome). Ruby is alone for much of the time and, afraid of night's darkness, she concocts elaborate mythical stories to survive, retreating into a private world. Eventually, she sets out to reconnect with her estranged father, and in the process transcends the fear that had gripped her so tightly.
