Matt Logan isn't looking forward to spending the school holidays with his grandmother and her new husband. He has to fly to Rotorua, where he doesn't know anybody, and he's a bit wary of his new step-grandfather. All Matt knows is that he's Maori and a bus driver. Along with his worries, Matt packs his pride and joy - a homemade metal detector, because, you never know, he might find something interesting. What he finds is Juzza, who lives over the back fence and wants to join a local gang. When the boys unearth a handcuffed skeleton, a chain of events begins to coil around them. Together they are thrown into a deadly search for treasure when the local gang boss decides to exploit their find for himself.
