The Truth Beneath Plot Summary
Read the complete plot summary and ending explained for The Truth Beneath (2016). From turning points to emotional moments, uncover what really happened and why it matters.
Kim Yeon-hong [Son Ye-jin] seems to have a flawless life: she is beautiful, married to the charismatic young politician Kim Jong-chan [Kim Joo-hyuk], and her once-troublesome adolescent daughter Min-jin [Shin Ji-hoon] is now doing better at school. When Jong-chan announces a bid to unseat the powerful incumbent No Jae-soon [Kim Eui-sung], the couple’s dreams are put to the test as the election looms. A few days before the vote, Min-jin vanishes, and what begins as a worried search rapidly deepens into a web of secrets that threatens her family and their public image.
At first, Yeon-hong and Jong-chan fear Min-jin has run off to draw attention, a tactic she had used before. But Yeon-hong soon discovers that the friend Min-jin claimed to meet does not exist. The clues point to a troubling dynamic at the school: a poor girl named Choi Mi-ok [Kim So-hee], who nonetheless wears an expensive watch that resembles Min-jin’s. The contrast between appearance and reality unsettles Yeon-hong, heightening her suspicions as she confronts Mi-ok. Mi-ok’s presence in the narrative ties into a larger pattern of manipulation and desire for power that threads through the story.
As Yeon-hong pushes deeper, she uncovers evidence of a leaked set of exam papers from a young female teacher at the school. The teacher admits she leaked the papers, claiming the motive was to help Min-jin and Mi-ok improve their grades and avoid bullying, a tactic that backfires in the face of escalating tensions. Yeon-hong’s attempts to get to the bottom of Min-jin’s disappearance lead her to seek answers beyond the police, even consulting a shaman, but the trail grows colder as the investigation stalls. The police eventually discover Min-jin’s dead body in the woods, a revelation that rocks Yeon-hong to the core and pushes her toward seeking citywide sympathy for Jong-chan’s campaign.
Crucially, Yeon-hong’s pursuit of truth strains the political landscape. She confronts the rift between the party’s push for a sympathy vote and the grim reality surrounding their daughter’s death. Meanwhile, the family’s driver, Jong-chan’s driver [Park Jin-woo], becomes a significant, if shadowy, figure in Mi-ok’s world. Yeon-hong’s investigation leads her to an abandoned building where Min-jin and Mi-ok once practiced music, and attempts to hypnotize Mi-ok fail to produce clear answers. A lie detector test shows Mi-ok lying about burying Min-jin’s body but accepting that she did not kill her friend, complicating the narrative of responsibility and guilt.
Yeon-hong’s theories evolve as she learns Mi-ok is the daughter of Jong-chan’s driver, a connection that fuels a jealousy-based hypothesis about the motive for murder. Yet concrete evidence remains elusive, and Yeon-hong continues to press for the truth. She discovers a secret hideout connected to the girls’ music, along with buried money, a clue that deepens the mystery rather than resolving it. When she corners Mi-ok, the girl finally reveals that Min-jin and Mi-ok had become best friends because they shared a taste in music. Their bond grows tense as Min-jin begins to suspect the schoolteacher might be having an affair, prompting them to use a hidden camera in a car air freshener to record the teacher with her lover. The girls blackmail the teacher for money, a desperate move born from financial strain in Mi-ok’s family.
One rainy night, tragedy strikes: Min-jin is struck by a car, and Mi-ok, who had hidden nearby, witnesses the aftermath and later uses the driver’s car to murder the killer before carrying Min-jin’s body into the woods. Mi-ok then takes the killer’s phone and disappears, leaving Yeon-hong with a crucial clue that shifts the investigation toward those who hired the hit. Yeon-hong, convinced that the person responsible must be brought to justice, plans to confront the mastermind with the evidence the girls amassed.
The tension culminates in a dinner scene that becomes a turning point. Yeon-hong suggests that No Jae-soon and his campaign could capitalize on the tragedy, but the real twist unfolds through a series of flashbacks: the man with whom the teacher was involved is Jong-chan. It becomes clear that Jong-chan had unknowingly hired a contract killer to murder his own daughter. The revelation exposes a devastating web of manipulation, jealousy, and political expediency that has consumed the family from within. Yeon-hong confronts Jong-chan, ties him up, and, in a brutal reversal of the public’s sympathy, uploads a sex video featuring him to the internet, dismantling his career as he watches in powerless horror. The film leaves viewers contemplating how far ambition, fear, and parental desperation can push a family toward ruin, and who bears the ultimate responsibility for Min-jin’s untimely death.
