 Er Woo Dong translates to "entertainer," a rough approximation of the duties of 14th-century Korean courtesan Er Yoon Chang. After a lifetime "in service," Er Yoon Chang retires to a faraway village. Meanwhile, her powerful father, ashamed of his daughter s lifestyle, dispatches an assassin to do her in. Er Yoon Chang is protected by her faithful deaf-mute bodyguard, but only up to a point.
