St Sebastian's School in Grimesford is built on the boggy remains of a medieval plague pit, this once proud school's dodgy nineteenth-century foundations are causing it to slowly subside.

Every year it sinks a little further into the ground, and every year the ghosts of the plague victims underneath become more disgruntled. The ghosts - egged on by their spooky ringleader, Edith Codd - decide to get their own back, and they're willing to play dirty. Really dirty. 

But the ghosts haven't reckoned on a new kid and his mates in year seven. Can James and his friends get to the bottom of the problem and flush out the ghosts, or will every terms at St Sebastian's be plagued with misery?
