Plot.
Hae-won is a middle-rank officer working in a Seoul bank. A stern, tense, single woman, she is brought down by work-related status and her hypercompetitive mentality. Desperate for a change of pace, she takes up an offer from a long-forgotten friend to take a vacation in Mudo, a desolate Southern island where she spent her childhood.
Arriving at the island, she is warmly welcomed by Bok-nam, with whom she had a close friendship when both were in their teens, but whose constant letters she's since ignored. Life on the undeveloped, socially regressive island is hard, and Bok-nam is treated as little more than a slave by her abusive husband Man-jong, his lustful brother, and the local mean old women. All of Bok-nam's love is reserved for her young daughter Yeon-hee, with whom she tries to escape for a better life. The attempt is foiled by Man-jong and the villagers, and her daughter is accidentally killed in the struggle. Hae-won as a friend does not do anything rather than be a bystander. A mainland investigation is blocked by the locals and Hae-won does not support Bok-nam's case. Bok-nam finally snaps and vengefully kills anyone she can get her hands on, armed with a sickle. Terrified, Hae-won escapes the island and returns to the mainland. 
A few days later, Bok-nam travels to Seoul and tries to kill Hae-won, because she refused to help her or her daughter escape even after knowing the situation or to back up the murder story to the investigator. During the fight, Hae-won kills Bok-nam with her recorder striking her neck. Bok-nam dies in her lap reminiscing the good old days with Hae-won. Hae-won back in her apartment starts reading Bok-nam's letters and lays down the floor emotionless.
