Summerdown has merged with another school and it’s all change for the teachers. Bob is struggling to adjust: he’s been demoted, and his new boss seems to be a hit with the women.

Penny makes a pass at Ewan, but it all ends in humiliation. Meanwhile, Ben is ordered to babysit some pensioners who are visiting the school which forces him to confront his own prejudices.

Ewan is thrown into turmoil when he finds out that a pupil, John, fancies him. All his attempts to handle the situation sensitively backfire horribly.

It is Obesity Awareness Month and Ben becomes obsessed with Lindsay’s weight. It’s purely selfish, of course; he’s worried her death would be bad for his own stress levels.

It’s Religious Tolerance Week and the teachers prepare to represent their allocated religions at the Tolerance Fair. Meanwhile, Bob finally takes delivery of his new wife.

After discovering Penny’s real surname is Eichmann, the others take pleasure in winding her up. She’s blonde, she hates foreign food, she has no black friends—could she be a racist?

No sooner has Damien announced that he doesn’t need a girlfriend, than he falls for the substitute teacher Anna. But an unfortunate incident with a pupil and an icing bag has rendered him impotent.

While trying to get out of Bob’s stag do, Ben is reminded of a ouija board prediction: he’s going to die on Friday. Then he sees a miracle. So God must exist, and there’s an afterlife to contend with.

The school is trashed after the Christmas party, the teachers are hungover, Bob is getting married in the playground—and the Ofsted Inspector is due. Happy Christmas, everyone!
