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. For Alfie this means a new class member, Cleopatra, and a tough decision to make – stand by his girlfriend, Miss Gulliver when she leads the teachers on strike, or sacrifice himself to save his class from failing their exams.

It's Abbey Grove's sports day and Fraser has hired the most inappropriate new sports teacher to oversee events – Preet. Alfie sees this as the perfect opportunity to challenge Miss Gulliver's ex-boyfriend Richard to an endurance event, which Preet offers to design. But with a steroid scandal rocking the school and Alfie desperate to win by any means possible, will he make it over the finish line with his dignity intact?
