Onna lives with her parents, her three-year older brother and her grandfather in an inn in the village of Pellona, which her parents run. In the middle of winter, sixteen-year-old Wandor comes her way. He is badly injured, suffers from amnesia and, after being treated by the doctor, is put up at the inn to recover. Onna finds him intriguing and suspects ever more strongly that he has not lost his memory at all, but is pretending to. Why? When she notices that others, too, such as the village chief and the priest of the Brotherhood, are trying to find out his secret, Onna suspects that his secret may put him in danger. To be able to help him, she tries to find out his secret before the priest or the village chief do. Will she succeed?
