When Jess and Jack Rayworth reluctantly enter the gates of their latest school Hilltop Academy, they don't know they're entering the training ground for a secret agency. An agency set up to stop damage inflicted on the planet through the greed of a sinister organisation known as the Lobby. They soon work out that Hilltop also has something to do with their missing parents. And following their hunch, they are launched into a battle for survival deep in the Amazon rainforest, trying to help save someone else's home and family. But will this help them save their own?
