On his 26th birthday Simon is persuaded to steal a statue from Summerdown School. He spends the next week worried the authoritarian Claire will find out. Simon also gets it in the neck from Jenny, who feels he is too undisciplined, and he’s in for a shock when he realizes his girlfriend Maggie is in fact a police officer.

Clare enjoys winding the teachers up about the upcoming Parent’s Evening. Susan also begins to fear that the job of Year Head will go to Jenny, who has been impressing Clare with her strict teaching skills. Simon must wriggle his way out of trouble after getting caught smoking a joint with a student.

Simon finally gets kicked out by his dad and is forced to move in with the boring Science teacher Steve. In the end, he decides even living in Brian and Kurt’s pigsty would be better and he moves in the following day. Things go from bad to worse as Maggie threatens to dump Simon for being unromantic. However, Carol’s idea of a romantic dinner goes down a treat and all is alright again.

The male teachers all become insecure about their respective relationships when Clare announces teaching sex education is to be taught in class. Simon makes his usual mess by advising a pupil to dump his girlfriend if she doesn’t sleep with him. Jenny sorts out Susan’s marital problems by having a stern word with Peter.

Simon gets sick of living with Brian and Kurt and Maggie eventually lets him move in with her. At the House Warming party Jenny gets off with Brian—something she later seriously regrets.

Susan’s marriage falls into turmoil and she has a nervous breakdown after all her advice goes wayward. Simon is offered a permanent post by Claire, but begins to wonder if he is in the right profession after his pupils mock results turn out to be disastrous.

It’s another bad week for Simon, as first he gets blamed for a fiasco involving teachers faces on nude bodies, then falls out with fellow English teacher Bob, who will be interviewing him for his promotion. He also witnesses a pupil going into labour and realises how inadequate his knowledge of the female body is. Brian and Kurt are involved with a face off over Carol and Liz regarding access to Claire’s office.

Liz’s gossiping around has resulted in a showdown of sorts between Simon and Jenny. Simon eventually backs down after making some untrue accusations which he heard from Brian and Kurt. All the staff are preparing for the End of Term party. Despite Clare’s best efforts to the contrary, everyone has a great time—Simon and Jenny even go home together. Another surprising development is the pairing of Kurt and Carol.
