Amid the concrete walls of a dark cell, the pain of betrayal cuts deeper than the freezing cold. Nami, who finds herself trapped in the brutal order of a women’s prison after being betrayed by the man she trusted, is locked away among sadistic guards and inmates struggling to survive. Directed by Shunya Ito, this harrowing film follows a woman crushed by the system as she hones her inner rage. At the intersection of action and drama, the desire for revenge becomes not merely a reaction, but a means of survival. Every face bears a different crime; every corner holds a fading hope.
