Synopsis

After her grandmother passed away, Na Su-Hyeon returned to her hometown after settling down in the city. As if drawn by something, Su-Hyeon climbs Mount Obong, which her grandmother had told her never to climb while she was alive. When she gets lost in the mountains and is caught up in strange events and is in danger, Su-Hyeon receives help from a man named Seo Moon-Ju, who is still fine even after being beheaded... Moon-Ju tells her that Su-Hyeon is the reincarnation of her former divine mother, the shaman Kang Yu-Hwa, and that the strange events that are unfolding before her eyes happened because Su-Hyeon climbed Mount Obong. Moon-Ju seems very suspicious, but after she encounters ghosts who steal the weapons buried in Kang Yu-Hwa's grave and gain power, Su-Hyeon feels a sense of responsibility. Moon-Ju suspects that the evil spirit that drove Kang Yu-Hwa to death must have been sensed Su-Hyeon's aura and dug up her grave. In the end, Su-Hyeon decides to listen to the ghosts' voices and retrieves the relics with Moon-Ju... Will they be able to defeat the evil spirits and end Moon-Ju's eternal curse ?
