A man plummets to his death from a mountain peak. Did he jump – or was he pushed? When detective Hae-joon (Park Hae-il) arrives on the scene, he begins to suspect that Seo-rae (Tang Wei), the dead man’s widow, may know more than she’s letting on. But as he digs deeper into his investigation, Hae-joon finds himself trapped in a web of deceit and desire that suggests the darkest mysteries may lurk inside the human heart. Brilliant performances from the two leads highlight the latest masterpiece from this peerless Korean director.
