Tightly plotted, critically acclaimed Secret Investigation Record blends sci-fi chills and historical thrills in this fantastic story. Based on real cases from Korean history, this "X-Files"-esque drama pulled in high ratings for its genre. Kim Hyung Do, originally an ordinary inspector for the government, rises in the ranks due to his undying passion for his trade. Chosen for a secret organization which investigates unexplained phenomena, he soon stumbles across a series of mysterious, supernatural events, and sets out to discover the truth behind them. In his quest he is helped (and sometimes hindered) by Heo Yoon Yi, whose enthusiastic belief in the supernatural stands in stark contrast to his own cool-headed logic (making them the Mulder and Scully of the K-drama world). Wonderfully filmed and suspenseful, this drama skillfully weaves together mystery, drama, and a little romance in a concoction of science fiction and historical intrigue. Kim Ji Hoon stars as a government investigator in 17th century Korea. Im Jung Eun (Swallow the Sun) and much-loved Kim Gab Soo (Cinderella's Sister) co-star.
