It is March 1348. Evil lurks in Crowfield Abbey and the building is starting to collapse. Fay creatures have fled the surrounding forest in terror. Repairs begin and William is given the job of lifting floor tiles in a haunted side chapel. There he finds a box from an earlier pagan time containing a small wooden bowl, covered with strange warnings and symbols. The bowl is cursed and a hideous demon is unleashed within the Abbey's walls that will wreak unspeakable havoc. Can Will and his friends summon help in time or is it the end of Crowfield forever?
