An energetic rock musical comedy, Starstruck tells the story of reluctant Sydney barmaid Jackie Mullens, whose life is seemingly being wasted in her family's working-class pub. It also doesn't help that business is going downhill fast. Jackie's dream is to be a singing star, and in this she is being assisted by fourteen-year-old Angus, her odd-ball cousin. Uninterested in the mundane task of learning at school, Angus puts into action a number of crazy showbiz ideas that he believes will make Jackie famous. He manipulates the media, pulling off a brazen publicity stunt that turns Jackie into the celebrity of the day. Throughout all this, the pub continues to deteriorate. As Jackie attempts to deal with mounting career obstacles, she begins to realise that if the family business were to collapse, not only would it break the family up, but she'd also be forced to get a job to pay for somewhere to live. When Angus pulls off another amazing stunt at the Opera House on New Year's Eve, however, Jackie is able to save the pub and realise her dream in one magical evening.
