When a team of CHERUB agents uncover a link between eco-terrorist group Help Earth and a wealthy religious cult known as The Survivors, James Adams is sent to Australia on an infiltration mission. It's his toughest job so far. The Survivors' outback headquarters are completely isolated. It's a thousand kilometres to the nearest town and the cult's brainwashing techniques mean James is under massive pressure to conform. This time he's not just fighting terrorists. He's got to battle to keep control of his own mind.
