At St. Misbehaviour's (real name: St. Saviour's), the kids are in charge and keeping the teachers under control is no mean feat - especially their new Geography teacher, Mr Rugg. He's a man with a monstrous mission: to close down 7R's beloved school...Look out, peaceful village of Little Twitterings! Class 7R are off to the country with crazy Science teacher, Miss Twine and her bizarre companion, Alberta (who's a skeleton). Can Percival Rugg catch the kids up to no good on their fun-filled trip? Or can the canny kids outwit their ghastly geography teacher once again?
