Film censor Enid takes her work seriously. With meticulous zeal, she recommends the redaction of extremely violent, brutal, bloody and sexually explicit scenes for censorship, without which no film can be released. Her sense of duty is reinforced by feelings of guilt from her childhood. The mysterious disappearance of her younger sister still weighs heavily on her. Enid has not yet given up the search for her, though her parents have decided to have her sister pronounced dead. When Enid is assigned to censor a film from the archives, it rekindles fresh memories of that time. Becoming increasingly obsessed, she picks up the trail and embarks on a nightmarish, feverish quest during which the lines between fiction and reality become blurred.
