 At the dress rehearsal there s a bad feeling about the unrealistic set and especially the lack of motorbikes. Mr. Bronson has been unravelling Gonch s entire video scheme, but things are desperate enough for the teacher to do a deal with Gonch, to at least copy some motorbike sound effects. Banksie wants to make a contribution to the musical, but no-one will hear him out. The first half of the performance goes moderately well, but even the mayor observes that it lacks punch. Banksie s idea is revealed - a set of real-life bikers is outside the school, ready to bring on their machines for a finale, but Mrs. McClusky has caught wind of the plan, and has to be persuaded first.
