In 1867, Shin Jae Hyo leads the Dongrijungsa which teaches pansori (traditional Korean musical storytelling). A young girl, Chae Sun, who wants to perform pansori, appears in front of him. Chae Sun has dreamed of performing pansori since she first heard Shin Jae Hyo perform when she was little, but Shin Jae Hyo turns her down because women are not allowed to perform pansori. Chae Sun then disguises herself as a man and enters the Dongrijungsa to learn pansori, but Shin Jae Hyo doesn’t accept her as his student. One day, he hears Daewongun, the most powerful man in Joseon and the father of the King, is going to hold a national competition of pansori performers known as “Naksungyeon.” Shin Jae Hyo decides to teach Chae Sun who has a true voice to perform “Chunhyangga.” If anyone finds out that Chae Sun is a woman, Shin Jae Hyo and Chae Sun will both face death.

Based on the true story of Jin Chae Seon (진채선), Joseon's first female pansori singer in 1867.
