Mysterious incidents are written in the Annals of the Joseon Dynasty that cannot be explained through science.
In this Joseon-era alternate history, Kim Hyung-do (Kim Ji-hoon) is an inspector with a single-minded focus on his investigations into administrative misdeeds. It brings him into direct contact with a secret organization within the government, who secretly record strange, paranormal, possibly alien phenomena. Hyung-do finds himself working with this group as he hopes to uncover the truth that led to his mentor’s death. While he eschews superstition and seeks logical, realistic explanations, fellow investigator Heo Yoon-yi (Im Jung-eun) approaches each case with an open mind and secrets of her own. Wiki.
