About the title
The once-legendary hitman Wi-gang is now an exemplary family man. When his wife goes on vacation, she asks her beloved husband to do her a small favor — look after her friend's 17-year-old daughter. Yoon-ji is a very naive and careless girl who must not get into trouble. But when Yoon-ji is kidnapped, Wi-gang realizes he must recall his past and embark on a path of revenge and violence to bring his charge home safe and sound.
