PART 1: St Dunstan’s holds a weekly remedial class for particularly naughty or stupid pupils. It is presided over by the stern Ms Robenshaw who uses strict discipline to bring the unruly students back into line. And woe betide any boy or girl that she catches misbehaving in her class… The pupils that are required to attend the remedial class have arrived and sit fidgeting nervously in their seats. Already bored, some of them seek ways to make the ordeal more interesting. But it’s very risky – mucking about in Ms Robenshaw’s class comes with potential consequences.
