Sophie doesn’t know there’s a dead girl in her head, and that the dead girl is her twin sister, Georgia.

When faced with a ‘sliding doors’ moment – the opportunity to travel across Australia with freelance photographer Clinton West who is on assignment at Cocklebiddy Cave, on the Nullarbor Plain – she turns it down. Georgia on the other hand, who didn’t survive their mother’s pregnancy but who lives on as a voice in Sophie’s head, is angry and frustrated with Sophie’s boring life so decides to break free and go without her.

Travel across this incredible country with Georgia as she learns more about her sister, and life, than she anticipated. Through the extreme sport of cave diving, and the force of Mother Nature, Sophie’s Sister explores the fine line between life and death. It uses the extraordinarily beautiful, dramatic and dangerous landscape of inland and coastal Australia as its canvas. It also explores the expectations we place on ourselves and others when it comes to excitement and contentment. Dreams don’t have to be big. The small ones mean just as much.
