Warning: This article contains spoilers for Decision to Leave.

Filmmaker Park Chan-wook crafted the devastating ending of Decision to Leave, his newest film (out today), decades before he became a director.

In the romance mystery, Park Hae-il and Tang Wei play doomed love interests, a detective and his murder suspect, drawn to each other despite the circumstances. Layered with the Oldboydirector's signature twists, the noir concludes with the suicide of Tang's Seo-rae — one aided by the sea, and a callback to detective Hae-joon's (Park) instructions to dispose of her dead husband's smartphone in the ocean. She digs a hole in the sand, crawls in, and waits for the tides to wash over the opening. When a frantic Hae-joon arrives, traces of the hole, and Seo-rae, are gone.
