As country bumpkin police sergeant Kwak Do-won investigates a series of murders that appear to be connected to a strange, sense-deranging sickness that’s going around, local villagers fix the blame on a Japanese drifter suspected of being an evil spirit in Na’s atmospheric tale of demons, shamans, exorcisms, and animated corpses, steeped in ancient east Asian folklore and Christian symbolism. A sporadically hilarious, brilliantly plotted work of insinuating, creeping terror that turns shopworn horror tropes inside out to create something entirely unpredictable and genuinely disturbing. “Korean cinema has a new genre maestro… A supremely unsettling evocation.” —The Guardian
