Wendell is a high school outcast who lives a lonely, suburban existence, losing himself in books in order to avoid his distant, motorcycle-riding stepfather, Ted. When the school bullies convince Wendell to venture into the forest around their neighborhood and explore the long-abandoned Renaissance Faire grounds they all believe to be haunted, Wendell is surprised to find a man living in the barn - and even more surprised by the man himself. His new acquaintance seems the definition of crackpot, believing himself to be a medieval knight named Sir Habersham, tasked with the duty of slaying the dragon he insists is wandering the woods. But when Wendell starts hearing rumblings - and listening to Habersham's stories - he starts to wonder if, perhaps, it could all be true. In a heartfelt coming-of age story, Wendell must defy logic in order to follow his heart.
