Young teacher Bernard Hedges is determined to improve the new tough East London school that he has been assigned to. This means he has to deal with 5C, the worst class in the school, and Potter the notorious school keeper.
Bernard has to do some quick thinking when someone from the art class shows him their drawings of the pupils of 5c. This would normally be ok, but the artist has, for some reason, drawn them in the nude!
When 5c pupil Maureen is seen coming out of teacher Bernard's flat, the school rumour mill starts working overtime.
The inexperienced Alf finds himself taking over as landlord at the Brown Cow.
The return of a Greek Cypriot student causes a lot of disruption within the school. Bernard Hedges tries to deal with the boy with a firm hand and winds up fearing for his life.
Complaints are made about the state of the library, and the noise coming from there, after 5c are given custody of the key to the door.
Bernard is surprised when he finds out that the new trainee teacher is an old girlfriend. When she becomes more successful at dealing with 5C than he is though, he starts to see her as a threat.
As the end of term approaches, Bernard wonders what the students will give him as a Christmas present. And then he finds out that 5C's old teacher has recovered and will be returning to teach them next term.
