Deena Harrison was one of Leighford High School's “characters” - setting fire to the toilet block and throwing boys down stairs. But she had the voice of an angel and could act the skin off a rice pudding. The autumn she came down from Oxford, there was something of a crisis in the Drama department at Leighford High. Mrs Carmichael was in danger of losing her baby and the Little Shop of Horrors was in danger of closing down. So Deena comes back to help out. And people start dying…just tragic accidents of course - loose cables, carelessly placed ladders; simple health and safety issues, surely? And then Deena's old Head of Sixth Form stumbles into the spotlight... the return of Mad Max.
