During the time of Queen Jinseong, the last ruler of the Silla Dynasty, the kingdom is ravaged by an onslaught of bandits. Returning from his victorious campaign against the bandit hordes, Kim Won-rang is summoned by Queen Jinseong. The queen tries to seduce Won-rang, whom she loved in the past, and orders that his wife Yeo-hwa be driven from the capital. While traveling deep in the mountains holding her baby, Yeo-hwa is set upon by bandits. She flees and jumps into a lake. Later, Kim Won-rang rescues Yeo-hwa from the lake and she survives. Old servants talk in whispers that the lake is haunted by the spirit of a thousand-year-old fox and it is strange that Yeo-hwa did not die. One night, Yeo-hwa awakens from her sleep and ventures from the house. She seduces the bandits who killed her baby and murders them. Director Shin Sang-ok, who made some of the best commercial films in the 1960s, delivers the topics of never-ending stories such as the dynamics of a ruler and subjects, and power and sex through the sentiments of a horror movie.
