During their time at the camp, Molly notices a rain cloud in the sky and deduces that if she, Gracie and Daisy were to escape and go back to Jigalong on foot, the rain will cover their tracks, so nobody can track them. Gracie and Daisy decide to go along with Molly and the three girls sneak off, without being noticed and run away. Moments after their escape, an Aboriginal tracker, Moodoo, is called in to find them. However, the girls are well trained in disguising their tracks. They evade Moodoo several times, receiving aid from strangers in the harsh Australian country they travel. They eventually find the rabbit-proof fence, knowing they can follow it north to Jigalong. Neville soon figures out their strategy and sends Moodoo and Riggs after them. Although he is an experienced tracker, Moodoo is unable to find them.
