Conor Shaw (Conor O'Toole ) is an overachiever. He's back in his old school, teaching his old classmates. The students hate him. The teachers hate him. Why? Because he's the Student Teacher.
First day at work, can Conor win the respect of his old classmates and teachers? Can he help his useless history class to scrape a pass? Can he go out with a student? No. No he can't.
It's the week of the mock exams. Conor is failing to connect with his class when Mr Clancy insists he do extra work with some of the school's hurling team.
Conor brings his class on an excursion to the local heritage centre, while school staff Mattie and Clancy panic about the visiting school inspector.
Conor has to get the class back before the School Inspector finds out that they're missing. He better be careful, Mr. Clancy and Mattie the Caretaker are looking for him too.
