Struggling at home and at school, Duncan decides to try out for a local rock band. He plays the bass in the school orchestra, but it is a long way from band camp to rock star. Joining a heavy-metal band, he tries to fit in, dumping his old friends and trying to walk the walk. When his dad�s new girlfriend starts to teach him about real rock music and introduces him to her musician brother, Duncan discovers that there is more to being a guitar hero than playing in a heavy-metal band.
