Corto is a young girl from Nuï, an isolated paradisiacal archipelago in the middle of a vast ocean. She loves drones and pilots her father's with dexterity to make deliveries.
Her dream would be to become a drone pilot but for that, she would already have to be able to participate in the races that take place in Nuï. And if, on top of that, she could catch the attention of Loopi, the best pilot in town. When the opportunity presents itself, Corto takes it. She then begins an impressive race at the controls of her father's old drone. Will she manage to beat the formidable Shore Scrubbers?
