From a mountain peak in South Korea, a man plummets to his death. Did he jump, or was he pushed? When detective Hae-joon (Park Hae-il) arrives on the scene, he begins to suspect the dead man's wife Seo-rae (Tang Wei). But as he digs deeper into the investigation, he finds himself trapped in a web of deception and desire. From master filmmaker Park Chan-wook (Oldboy, The Handmaiden), who won Best Director at Cannes.
