Park Chan-wook’s Decision to Leave is a film that lingers long after the credits roll—a hypnotic blend of romantic longing, moral ambiguity, and noir intrigue. This review will explore every facet of the film: its intricate plot, complex characters, central themes, box office journey, similar cinematic experiences, reasons to watch, a thoughtful conclusion, and answers to the most common questions. Here is an in-depth, humanized look at one of the most celebrated films of recent years.

Detailed Plot Summary

Decision to Leave unfolds in modern South Korea, where detective Jang Hae-jun, a dedicated but insomniac investigator, splits his life between the bustling city of Busan and the quiet town of Ipo, where his wife Jung-an works as a nuclear power plant manager. Their marriage is strained by distance and Hae-jun’s obsession with his work, leaving him emotionally adrift.

The story begins with the mysterious death of Ki Do-soo, a retired immigration officer and mountaineering enthusiast, found dead at the base of a mountain he often climbed. Hae-jun and his partner, Soo-wan, are assigned the case. Suspicion quickly falls on Ki’s much younger wife, Song Seo-rae, a Chinese immigrant working as a caretaker for the elderly. Her lack of overt grief, bruises, a suspicious scratch, and a tattoo of her husband’s initials all paint a picture of possible guilt.

Hae-jun’s investigation becomes deeply personal. He stakes out Seo-rae’s apartment, watches her through binoculars, and even follows her on her daily routines. As he observes her, a strange intimacy develops—Seo-rae is fully aware of his surveillance and even manipulates it, planting false clues and performing grief for his benefit. The detective, initially convinced of her guilt, finds himself increasingly drawn to her enigmatic presence.

Seo-rae’s background is as mysterious as her behavior. She confesses to Hae-jun that she euthanized her terminally ill mother in China, at her mother’s request, and that she came to Korea to climb the mountain her grandfather, a Korean independence fighter, loved. Seo-rae provides letters written by her late husband, some of which suggest suicide, and Hae-jun, swayed by emotion and her apparent vulnerability, rules the death a suicide, despite his partner’s doubts.

Their relationship grows more intimate, though never overtly romantic or sexual. They visit temples, share meals, and confide in each other. Hae-jun’s professional boundaries blur as his obsession deepens, and his marriage suffers as a result.

Thirteen months later, Hae-jun, now living in Ipo with his wife and suffering from depression and insomnia, stumbles upon Seo-rae again—now married to Im Ho-shin, a wealthy investor. When Ho-shin is found dead in his swimming pool, Hae-jun is convinced Seo-rae is involved. She admits to draining the pool to spare Hae-jun the sight of blood, but a Chinese immigrant named Sa Cheol-seong confesses to the murder, claiming Ho-shin defrauded his family. Sa insists Seo-rae is innocent and reveals he tracked her movements.

Hae-jun, still unable to let go, investigates further. He discovers that Seo-rae manipulated evidence in both deaths, exploiting his feelings to evade justice. In a devastating realization, he understands that Seo-rae’s affection was intertwined with her desire to become one of his “unsolved cases”—an enigma he could never resolve.

The film’s haunting climax occurs on a remote beach. Seo-rae, after leaving a series of voice messages for Hae-jun, digs a pit in the sand and allows the rising tide to bury and drown her, choosing a fate that ensures she will remain forever unsolved in Hae-jun’s heart and mind. Hae-jun arrives too late, left to grieve a love that was always just out of reach.

Character Analysis

Jang Hae-jun (Park Hae-il)

Hae-jun is a man defined by his obsessions. His insomnia and emotional detachment stem from a life spent chasing mysteries—both criminal and existential. His marriage to Jung-an is loving but distant, and his sense of purpose is tied to his work. Seo-rae’s arrival in his life awakens a longing for connection, but also exposes his vulnerability to manipulation. Hae-jun’s journey is one of self-discovery, heartbreak, and the realization that some mysteries are meant to remain unsolved.

Song Seo-rae (Tang Wei)

Seo-rae is the film’s most enigmatic figure. Her past is marked by trauma, loss, and survival. She is both a victim and a manipulator, capable of deep emotion and calculated deception. Seo-rae’s relationship with Hae-jun is a dance of intimacy and distance—she draws him in, only to push him away. Her final act is both a confession and a sacrifice, ensuring that her story will haunt Hae-jun forever.

Jung-an

Hae-jun’s wife is compassionate and practical, representing the life Hae-jun could have if he chose stability over obsession. Her growing suspicion and eventual departure reflect the collateral damage of Hae-jun’s fixation on Seo-rae.

Im Ho-shin and Sa Cheol-seong

Ho-shin, Seo-rae’s second husband, is a wealthy but morally dubious figure whose death reignites Hae-jun’s suspicions. Sa Cheol-seong, the avenger, serves as a red herring and a mirror to Hae-jun’s own obsessive tendencies.

Thematic Exploration

Obsession and Desire

At its core, Decision to Leave is a meditation on obsession—how it can consume, distort, and ultimately destroy. Hae-jun’s fixation on Seo-rae blurs the line between professional duty and personal longing, leading him down a path of self-destruction.

Moral Ambiguity

The film thrives in shades of gray. Seo-rae is both sympathetic and dangerous; Hae-jun is both protector and enabler. The audience is never allowed the comfort of clear answers, mirroring the uncertainty of real life.

Loneliness and Connection

Both Hae-jun and Seo-rae are profoundly lonely, seeking solace in each other even as their connection leads to ruin. Their relationship is marked by moments of genuine tenderness and devastating betrayal.

The Unsolved Case

The motif of the “unsolved case” runs throughout the film, symbolizing the mysteries of the human heart. Seo-rae’s desire to become Hae-jun’s unsolved case is both a plea for immortality and an act of self-erasure.

Death and Redemption

Death is ever-present, not just as a plot device but as a metaphor for transformation. Seo-rae’s final act is both a confession and a bid for redemption, leaving Hae-jun to grapple with the consequences.

Box Office Collection

Decision to Leave was both a critical and commercial success, particularly in South Korea and on the international festival circuit. The film’s nuanced storytelling, lush cinematography, and masterful direction by Park Chan-wook drew audiences seeking more than conventional thrillers. Its box office performance reflected the growing global appetite for sophisticated, character-driven mysteries and further cemented Park’s reputation as a leading auteur in world cinema.
