One fine fall day, three friends Su-Na, Min-Woo and Cheol-Kyu go on an impromptu trip for shooting a documentary they are preparing. They get lost in the midst of a mountain way and find a dreadful car accident scene. They pick up a navigation from the spot and use it for finding their destination. They thought they are being guided well by the navigation when they arrive at nowhere. Exhausted and hungry, they decide to have a barbecue in the midway. They soon realize the place is in fact a burial ground and start to run for their lives.
