16-year-old Beth is desperate to become friends with Lauren, the most popular girl in school. When the new stand-in drama teacher, Mr Carver, decides to put on a production of Romeo and Juliet, Beth finally ends up close to Lauren, as The Nurse to her Juliet. The friendship they develop is not quite what Beth had hoped, with Lauren failing to turn up to meet her and then using Beth as a convenient excuse for where she is staying that night. It's only when Beth discovers the illicit affair going on between Mr Carver and Lauren that her strange behaviour suddenly makes sense. Beth knows she must step in to stop the love affair - but the decision she makes has dire consequences for everyone involved.
