Patriot Kim Du-han faces a difficult situation when he is detained on a murder charge at the American army base in Itaewon. Things become worse when the prison chief is bribed by communists to make sure Kim Du-han does not survive.

A royal inspector Kim Sang-Won disguised as a traveler arrives at a village where they say a ghost appears to examine the details. Finally he is in the disguise of a resented spirit because of broken engagement and goes to the abandoned house where he discloses that Lee, a scholar, and his daughter In-Yeon murder the chief of the village Kim's whole family. Also he tells official circles and people that ghost can not be existed in any circumstances.
