Based on a true story, Duresori: The Voice of the East is shot in documentary style and tells the story of high school seniors Seul-ki and Ah-reum. Like other teenagers, they’re stressing over upcoming college entrance exams – and even more so when they’re forced to join the school choir in order to fill a remaining requirement. There, their unorthodox instructor blends the principles of classic Western music and traditional Korean song. Though at first they are reluctant to learn, they soon find a love for this exciting blend of music… and are forced to band together when the school cancels their annual summer concert. Will their music survive?
