After a car accident, Lindsay, Penny and Bob are the only few remaining teachers left to merge with a new school. Despite Clare's best efforts to make the staff bond, Damien and Ben ignore Penny and Lindsay's efforts at friendship.

Ben is petrified when he has to guide a group of OAPs around the school and Penny finds herself a new boyfriend. Bob is still discussing his 'fiancée' Sundander Sunitra and also plotting to have Ewan sacked.

During Gay and Lesbian Awareness Week, Ewan finds himself in an uncomfortable position with a student, and Clare wonders how lesbians 'function'.

Lindsay is made an example of during Fat Week and Ewan, Damien, Penny and Ben try to 'help' her diet. Meanwhile Penny is snubbed by Anthony, and Bob finds himself in a frenzy after his vasectomy.

Bob is very excited about meeting his new Thai bride Ping, but she is far more interested in Ewan. Ben takes Religious Tolerance week very seriously which results in a mini-war between the students.

Penny's family history is uncovered and she takes a turn for the worse this week. Meanwhile the issues of Racial Awareness Week extend to penis size. Meanwhile, Bob's sex life is suffering.

Damien finds himself attracted to the new supply teacher; however, after a cooking incident, he is rendered temporarily useless.

Ben appreciates how he has annoyed the Gods in every religion. He thinks he is going to die and so converts to each religion for a day. It is Bob's stag do in Dublin which everyone tries their hardest to avoid.
