The film is driven by several pivotal twists, beginning with the shocking and sudden death of Aunt Bella early in the first act. Her death shatters Ricky's newly found stability and forces the inciting incident: Ricky fakes his death by burning a shed to avoid returning to Child Services. When Hec pursues him, a fracture to Hec's ankle leaves them stranded in the bush for weeks. This isolation leads to a massive misunderstanding; the authorities misinterpret their disappearance and label Hec an abuser and kidnapper, escalating the search to a national manhunt.
The climax is a bombastic, vehicle-smashing chase through the desert-like Horopito car yard in a red truck named 'Crumpy'. Ultimately, Hec realizes they cannot run forever and surrenders to save Ricky from being shot by the police, taking the fall for their outlaw actions. The epilogue reveals a bittersweet but hopeful resolution: Hec serves time and moves into a halfway house, where he has learned to read. Ricky is placed with a supportive new foster family. Reunited, the two return to the bush to locate the elusive, thought-to-be-extinct Huia bird. Finding the bird confirms that despite the system's attempts to tear them apart, their bond and their connection to the wild remain unbroken.
