When Will finds himself in hospital, but unable to make anyone see or hear him, he realises that he never made it home from his first kiss with the school hottie. Knocked off his bike in a road traffic accident, Will is now officially dead - and a ghost. But somehow his best mate, Dougie, can still see him, and, what is more, increasingly Will seems bound to Dougie, going only where Dougie goes. Once they've exhausted all the comic possibilities of being invisible, they set about unravelling the mystery of Will's predicament. Is it something to do with that kiss, or the driver of the car that killed him and didn't stop? Maybe they will find an answer by investigating the rumour that there is an unhappy spirit haunting the ruins in the school grounds, and if so, why? What they discover is a long-buried mystery, which stretches its fingers right into the present…
