Abbey Grove School parents are worried about the impending arrival of the French exchange students, after Jean Claude and his French classmates ran riot leaving a wake of lovestruck teenagers behind them the previous year. This year, Fraser is determined to prove to the angry parents that he has got everything under control, especially with his right-hand man Alfie by his side. But is Alfie really the right man to entrust with a sex education class? Things are relieved when it turns out that Fraser had screwed up and accidentally arranged an exchange with the town of Hoogeveen in the Netherlands. But keeping things with them is easier said than done, thanks to one exchange student who every woman in the school seems to want.

Banned from organising his own trip after a disastrous previous outing, Alfie's class are sent on Miss Gulliver's field trip to a combined petting zoo and ink museum. Alfie's pretty upset to learn she has a blind date later that day, but things get even worse when the bus gets lost in the woods.
