The story of a woman in a mountain cabin in Gangwon province who’s been possessed by an evil spirit and a priest tries to stop it. 66 years and six months later, best friends Sang Goo and Jae Pil buy the cabin and Mi Na ends up intertwined with them after coming on a trip. The movie follows the terrifying things that happen to the group, and it’s described that the film is about the “satanic” goat-headed figure Baphomet. The character Sang Goo is said to be a man who appears intimidating but is really naive, while his friend Jae Pil is a man who seems rough on the outside but is actually warm. In contrast to the others from rich families, Mi Na grew up in a normal household in the countryside and she’s described as eccentric.
