The Swan Academy is under threat from closure due to a building development next door. Into this tense atmosphere come Cosmo and Cosima, the famous singing/acting twins from Hollywood. They are starring in Peter Pan and are learning to fly! A series of mysterious accidents in the theatre threaten to close the production, and Olivia's dad, who is flying consultant, gets the blame. Olivia uses her highwire skills to get hold of the development plans and a protest campaign is organised. But then another accident takes place - a rope has been cut through and the twins are nearly killed. Who is doing this - and why?
