Secret Investigation Record is based on cases detailed in the Annals of Joseon History with a bizarre twist; these incidents incorporate mysterious, supernatural elements that cannot be explained through science. Kim Hyung Do is an inspector of the state whose single-minded focus on his investigations into administrative misdeeds bring him into direct contact with these strange mysteries. Heo Yoon Yi is a government employee who aids him and attempts to understand these scientific impossibilities with an open mind, in contrast to his cynicism.
Episode 1
It is the year 1609, the first year in the reign of Gwanghaegun (Prince Gwanghae), a time characterized by political tensions and frequent occurrences of bizarre and mysterious phenomena that cannot be explained. Hyung-do, a government official and investigator, is asked to look into reports of an enormous UFO sighted in the eastern province of Gangwon-do.

Villagers attribute a rash of violent deaths which leave behind mutilated human remains to that of tigers. However, all of the victims are criminals, already marked for execution.
Episode 5
A storyteller holds court, weaving a tale of a woman’s murder that occurs on a dark, densely foggy night. Elsewhere, a man scribbles on a pad, clearly in a fugue state. He is a 'mudang', or psychic; a condition inherited from his mother. The tales he relays to the storyteller are remarkably identical in every detail to a recent spate of murders, therefore he is clearly the murderer.

A shaman is found dead, his body is strangely riddled with numerous small stab wounds after attempting to perform an exorcism.

Episode 8
Hyung-do is missing, and in her attempt to locate him, Yoon-yi is led to a blind prophet, a seemingly immortal man who has been imprisoned for 150 years. He is leering, lascivious, and downright vulgar, but clearly he can see… something.
