Minsuh, an anthropology student researching shamanistic rituals and the mudangs who perform them, has dismissed the supernatural her whole life. To her, mudangs are performers skilled at pleasing researchers. But as she gets deeper into her research, she’s afflicted with a mysterious shinbyeong – a holy sickness unique to Korea – causing her to start losing her mind. In her desperation, she turns to a ‘real’ mudang, but will she find salvation for her affliction or will she be driven further into her madness?
