Richard and Jade have never met their father. They don't even know his name. When their mother is killed in a road accident, the sixteen year-old twins are sent to live with him. Richard Chance doesn't seem particularly happy to meet his long-lost children. He is wrapped up in his work, a mysterious business conducted from the study of his flat. The twins are forbidden even to enter the room. Following him to a business meeting in deserted scrapyard, Richard and Jade are witness to their father's abduction. From then on, their world becomes a much more dangerous place. It seems that John Chance is some kind of spy, and the twins are now implicated. They can't trust anyone, their lives are in danger, and they are determined to rescue a father who doesn't want them, because he's the only thing they have left.
