Evie and Mia meet on a train on their way to St. Agatha's Boarding School for Young Ladies. Dropped at a deserted station, with no one to meet them, they trek through the pelting rain and darkness for miles until they find a sign to St. Agatha's which points to an unlikely overgrown track leading up a mountain path. A foreboding place, St. Agatha's School is surrounded by a sea of mist, and overlooks a loch. Coming face to face with the grotesque caretaker, Mandrake, is not the only thing to unsettle them. What is the significance of the strange rings worn by Miss Blackthorn, the head teacher - and why does everyone behave so oddly? The girls stumble across a forgotten burial chamber. Inside, lies the crumbling skeleton of Sister Beatrice, clutching a note which tells of a curse. Locked in the chamber as a punishment, the friends discover an old book within which is the antidote to the curse... but it is hidden in code.
