Alex doesn't believe in ghosts, but he is about to have his beliefs challenged. When Jimmy Devlin asks Alex and Donna to investigate the strange things that have been happening at The Priory, Alex seizes the opportunity to prove to his sister that ghosts don't exist. But as they start to look into the unexplained noises and shadowy figures, it becomes clear that unquiet spirits are far from the only problem facing the Devlin family. Can the twins solve the many mysteries of The Priory at the same time as outwitting a very dangerous enemy?
