Joseon X-Files

Mysterious incidents are recorded 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 strong focus on investigating into administrative misdeeds. This brings him into direct contact with a secret organization within the government. Dealing with strange, paranormal and possibly alien phenomena, the duty of this organization is to keep everything under control, leaving only secret records. Occurring during the reign of King Gwanghae, the episodes make various allusions to the political turmoils of the period. These individual stories are: In these various contexts, investigator Kim Hyung-do avoids superstition and searches for realistic explanations while investigator Heo Yoon-yi (Im Jung-eun) is more open to supernatural possibilities, including secrets of her own. The finale doesn't explain everything. Kim Hyung-do's last reply to Heo Yoon-yi is only "I know who you are".
