At a crossroads in her life, Sandra Porter knows she must find the courage to find her true self. She has lost her husband in tragic circumstances, and seen each of her adult children overcome adversity. Deciding it's time to push her boundaries, she makes a booking to trek the Larapinta Walk across the centre of the remote Northern Territory. World renowned nature photographer, Graysen Hughes has come to the outback seeking solace after the death of his wife. Always a loner, Graysen isn't happy when the tour guide insists on the participants walking in pairs. At least Sandra Porter is quiet and keeps to herself. After a suspicious accident and the sudden disappearance of their guide, the group struggles on, but then another accident occurs. It soon becomes obvious that someone doesn't want them to complete the trek. Without any means to call for help, Graysen and Sandra flee into the bush in an attempt to stay safe. Can they survive the wilderness in the heat and the rugged conditions, and can they both keep their hearts intact as they learn to rely on each other?
