Railey dreams of winning the drone races with her bio-robotic gecko friend, Atti. But when a bounty hunter crashes their biggest race yet, the pair are forced to flee to the feared Junker clans who mine the rubbish orbiting the Earth. Rescued by a couple of Junker kids, they discover a danger bigger than anything they'd imagined - but can three kids, a gecko and an ancient computer save the world against the huge trash bomb (and its power-crazed creator) threatening to destroy the planet?
