Mitch has decided it’s time to get a career, and fancies training as a teacher. The problem is he doesn’t have the grades to get into teacher training college, so has to go back to school to re-sit the exam. Mitch finds himself in a classroom full of sixteen year olds, including bad-boy Chris who quickly leads Mitch astray. It’s up to Mitch’s naively optimistic young teacher and his ‘parents’ Alice and Richie to keep him on the straight and narrow, so that the student may yet become the teacher.
