From a mountain peak in South Korea, a man plummets to his death. Did he jump, or was he pushed? When detective Hae-joon arrives on the scene, he begins to suspect the dead man’s wife Seo-rae. But as he digs deeper into the investigation, he finds himself trapped in a web of deception and desire.
Unfortunately the movie Decision to Leave is not yet available on HBO Max.
