Soon after a stranger arrives in the village of Gokseong, a mysterious disease that causes people to become violent and kill their families begins to spread. The police initially believe this change in behaviour is caused by wild mushrooms, but Officer Jong-goo begins to suspect that the newcomer could be responsible for the chaos after a woman accuses him of being a ghost. After Jong-goo's daughter gets sick, the cop goes directly to the stranger's home in the mountains to investigate. "The Wailing" has ghosts, exorcisms, and demons, making it a must-see film for horror lovers.
