This drama is a prequel to "Tale of the Nine Tailed", telling the story of the ghost hunting of the nine-tailed fox that was forced to land in the 1930s. It describes the process of Lee Eon (Lee Dong-wook) becoming a mountain god and the story of Lee Lang (Kim Bum) who was not laid out in the first season. Kim So-yeon plays the peerless beauty Yoo Hong-joo. She is rumored to be "ageless" and is the owner of the high-end restaurant "Myo-yeon-gak" in Gyeongseong. She was originally the West Mountain God, one of the four mountain gods who ruled the Johyeon Peninsula with Lee Eon.
