Four women - Yun-jin, Mun-ok, Hwa-ja and Yeon-sil - are inmates sharing a cell at a women’s prison. Yun-jin is guilty of murdering her violent husband to protect her unborn child. Mun-ok, previously a music professor, ran over her husband and his mistress to avenge her misery. Na-young, the guard responsible for these women forms a choir as a way to tame their wild behaviour, and Mun-ok is assigned the role of conductor. Four years go by and the prison choir performs in the national women’s choir contest. Their performance is a success and the women are permitted to spend time with their families afterwards. However, this joy is short-lived when Mun-ok is given her death sentence.less
