Twelve-year-old Elmo Blue just wants to fit in. His environmental-activist mother has agreed to buy him some new Nike trainers and it looks like at last he may have a chance of being accepted. But his angel friend, Kuba, seems to have other ideas... When the class go on a history trip to a remote part of Wales, Elmo, thanks to Kuba's promptings, finds himself embroiled in a war against bully Eddie Kilgour and his sidekick Mark. It looks as though Elmo himself could be history, unless Kuba can come up with some heavenly intervention!
