In general, Jeolla-do has been regarded as the home of pansori in Korea, but mastersingers such as Lee Dong-baek and Kim Chang-ryong were also known in Seocheon, Chungcheong-do in the early 20th century. Rapsori, adopting the form of fiction film, portrays the Korean traditional opera members and villagers proud of Seocheon's Pansori history, as well as a teenage singer who trains to become a mastersinger.

The film revolves around a man who is a former rapper and currently taking pictures and recording sounds. He accidentally meets a teenage singer and makes a pansori-journey in Seocheon. Rapsori, starting with an interest in pansori, reaches the moment of excitement that rap and pansori go together, and that the boundary is blurred between the past and present, the East and West. (NAM Da-eun)
