The film was inspired by the Kim Bu-Nam case. It features Yoo Sun, Nam Bo-ra in leading roles. Nam Bo-ra received two nominations for Best actress on the 2013 Baeksang Arts Awards and the 2013 Blue Dragon Film Awards.
Recently divorced, Yoo-lim (Yoo Sun) is currently living with her only daughter, Eun-ah (Nam Bo-ra). When she arrives at her new school, Eun-ah is frequently chosen, even though she has feelings for her classmate Jo-han (Shin Dongho). One day, she is brutally raped by Jo-han and his friends, who threaten to post pictures of the rape online to keep her quiet. Unable to cope with the trauma she endured, Eun-ah committed suicide. Since all the boys involved in the rape were still minors, the law didn't have the power to prosecute them to the fullest extent possible, and they walked away with just a slap on the wrist. Despite police Oh's efforts to appease him, Yoolim is still full of frustration and anger. So You-lim then sets out to make the boys' lives hell. She intended to kill Jo-han first, but when he lied that it was her friend's plan to rape Eun-ah, she brutally murdered the two people Jo-han mentioned. When Yoo-lim realizes that it is Jo-han who is behind it all, she enters his school and intends to kill him, but police officer Oh, who is investigating Eun-ah, rushes to stop him. When confronted, Yoo-lim, having had everything she's been through, tries to deliver the finishing blow, forcing Detective Oh to shoot her with his gun, killing her.
