Simcheong lives with her blind father, Mr. Sim, in Gokseong, Jeolla-do. When she learns her father's blindness can only be cured by jumping into Indang Water, she sacrifices herself and jumps in. She is saved by the dragon king and returns on a lotus flower. The emperor marries her and invites blind people to a banquet, where Simcheong and her father are reunited and his vision restored, demonstrating her filial piety.
