Lucy apprentices with her father in the family profession of vampire hunting. On a night that starts as routine observation, she notices a group of people moving toward the forest in a way that looks compelled rather than chosen — reminiscent of the disappearances that have been reported from the village. She follows. The trail leads through a castle door and into a place full of vampires who see her immediately. Some of them, unexpectedly, help her. Trapped inside Feste Castle, Lucy discovers that the events unfolding around her are not coincidental, and that someone among the vampires has made a decision about her future that she was not consulted about. The full moon is the deadline.
