It's time for the annual Average Primary School stage show. The bad news is that Principal Dorking is the producer. But the good news is that students who are chosen to be in the play will get an extra two days off school, so Mrs Payne comes up with a cunning plan to make sure all her Grade Five students are in the cast. Harry Harvard and Jesse Harrison get the lead roles and Samantha Smithers is their leading lady. They're about to become The Pirates of Average!
