It's summer term and Alfie Wickers is back in high spirits to get his class through their exams. But there is a shock for Alfie with the revelation that his dad Martin Wickers has been appointed as the new deputy head whose first jobs are to increase class sizes and fire a member of staff after Fraser has badly invested the school's money in his own clothing range, Dolce and GaBanter.
