Jeong-hye gives a birth to a baby boy in the prison. Her and other inmates create a women's choir to compete in the national choir contest, to meet and greet their families and loving ones.

Inmates at a woman's prison form a choir. Mun-ok, previously a music professor, 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 afterward. However, this joy is short-lived when Mun-ok is given her death sentence.—CJ Entertainment
