No Mercy

“Nothing can stop her from saving her missing sister.”

When her younger sister Eun-hye (Park Se-wan) goes missing, In-ae (Lee Si-young) starts working backward through the days before she vanished. What she finds is a trail of violence and sexual abuse carried out by a group of school bullies. Lim Kyoung-tack keeps the camera close on her as she goes after them, and the film stays on the two sisters: what In-ae owes Eun-hye, and what she will do to pay it.
