Alfie is a young man of 23 years, which is perhaps the worst teacher in the education system of the UK, while he is more a child than his disciples. Despite the obvious incompetence, the position Alfie in the school is stable thanks to Fraser, the school Director, who is struggling to be as cool as Alfie. He just wants to be all "best friend", and therefore cares for all problems of employees.
The school also runs miss Gulliver, the biology teacher, who like Alfie. She really cares about the school and students. Deputy Director Pickwell less good-natured. She is a teacher "old school" and does not understand their younger colleagues. She's a tough disciplinarian that wants to bring creationism into the school curriculum and would prefer to see a school without any pupils!
