Australia's beaches have seen a string of fatal shark attacks, and this film follows the scientists and officials betting that technology, not nets, is the answer. Marine biologist Paul Butcher runs the New South Wales shark management program, which uses smart drumlines to catch sharks alive, tag them, and release them unharmed. Drone operator Mark Atkins oversees what the film calls the world's largest drone-based beach surveillance system, feeding real-time alerts to swimmers and surfers while also logging shark movement data for researchers. Pilot Gabriel Roxburgh patrols the Ballina coastline, watching for the baitfish schools that tend to draw bigger predators behind them. The film sets this approach against neighboring Queensland, where traditional shark nets remain in use despite killing turtles and dolphins, and gives voice to critics on both sides: surfer and activist Daniel Webber, who argues the new methods leave people less protected, and conservationists Brylee Robinson and Bella Graham, who want the nets banned outright. The result is a clear-eyed look at a genuine policy fight, not a simple techno-fix story.
