Luke lives in modern-day Australia with his mother and stepfather Sam. Luke is burdened by a guilty secret: Sam has helped him to cheat in an entrance exam for a prestigious school. Lulach lives in eleventh-century Scotland with his mother and stepfather Macbeth. Luke is studying Shakespeares play Macbeth at school and dreams about Lulach and Macbeth at night. But gradually Luke realises they are more than dreams. Somehow he is reliving events that actually took place and they're nothing like Shakespeares version. Why did Shakespeare lie about who Macbeth really was? Does truth really matter? As the lives of Luke and Lulach intertwine the answers to these questions will change them forever.
