Fans of the X-Files or the sci-fi genre will enjoy this tightly woven, critically-acclaimed drama based on real Korean historical records. Kim Hyung Do (Kim Ji Hoon from "Stars Falling From the Sky"), an inspector for the government, is chosen for a secret organization within the government that specializes in unexplained, supernatural phenomena. Hyung Do soon stumbles across a series of mysterious events and sets out to discover the truth behind them. In his quest he is helped (and sometimes hindered) by Heo Yoon Yi (Im Jung Eun), a government employee whose enthusiastic belief in the supernatural stands in stark contrast to his own cool-headed logic. Wonderfully filmed and suspenseful, this drama skillfully weaves together mystery, drama, and a little romance in a heady concoction of science fiction and historical intrigue.
