In 1980, a teenage boy named Yoonhyuk, who was one of the students that took part in the student protests during the Gwangju massacre, was murdered and shot by one of the soldiers standing in the middle of the street, along his older brother Junghyuk. His parents buried their corpses in the mountains with great sorrow as they bid them farewell.

35 years later, Sungjong, a psychic university student who has the ability to predict his and others' futures and can connect with the dead as well as the living, thinks that he, as well as his best friend Myungsoo, has a connection with the two boys. After constantly dreaming about them, he figures that despite him or his parents never having heard about the two boys before, he is determined to find out about them and how he and Myungsoo are related to them.
