Expelled, expelled, expelled... Archie Riddle's life is turned upside down as his paranormal abilities lead to nothing but trouble. As his parent’s dream of a better life in England fades, Archie remains confident that his newly found powers will eventually earn him celebrity status. His next stop is Dogwood School, a former medieval castle turned school where he starts his attendance with a stern lecture from his new headmaster, "Don’t want you at Dogwood and I don’t want you fraternizing with my students." Despite this warning, Archie can't help but sense something is amiss. He quickly befriends the most unlikely student, a semi-bald nerd named Hamish and starts investigating the history of Dogwood. Archie discovers that the former medieval castle has been hiding some dark secrets. Together, Archie and Hamish explore ancient areas of the castle that were supposed to be sealed off forever. The spirits have a plan, and they’re going to leave Archie to take the fall.
