Alfie is shocked by the arrival of new teacher Kevin Schwimer at Abbey Grove and even more shocked to learn that he will be taking over Alfie's own class. Desperately upset that his class seem to be having a great time and actually learning proper, real-life GCSE history with their new teacher, Alfie is even more unhappy when he finds out which class Miss Pickwell has given him instead. With headmaster Fraser and Miss Gulliver both increasingly charmed by Mr Schwimer it is left to Alfie and Jing to uncover the truth behind this American imposter.

It is Valentine's Day and headmaster Mr Fraser has planned a special Abbey Grove Take Me Out to help the shy kids find love. New deputy headmistress Professor Celia Green is rubbing everyone up the wrong way, apart from Alfie's father Martin, who happened to go to teacher training college with her. Alfie is desperately trying to persuade Rosie to come to dinner with him, but is distracted by some shocking news from Chantelle. Will Rosie turn up to dinner and who is Martin Wickers's surprise dinner date?
