Walking on Thin Ice (2025)

Kang Eun-soo, an ordinary housewife and single mother, discovers a bag containing drugs worth hundreds of billions of won while going about her daily routine.

She initially intends to surrender the bag to the police, as she is known in her community for doing good deeds.

Eun-soo learns that her husband has pancreatic cancer, has drained their savings, and mortgaged their home, leaving her desperate to pay for his treatment and protect her daughter.

Overwhelmed by the medical bills and family crisis, Eun-soo decides against turning in the bag and instead keeps it to sell the drugs for money.

Eun-soo encounters Lee Kyung, her daughter's art teacher, who reveals his true identity as "James," a high-profile drug dealer living a double life in the drug underworld.

Lee Kyung recognizes the bag as his and proposes a dangerous partnership to Eun-soo, offering to help her sell the drugs in exchange for a share, leveraging his connections.

Eun-soo, driven by desperation to save her family, agrees to the partnership with Lee Kyung despite the risks.

As they begin selling the drugs, Eun-soo and Lee Kyung navigate secrets and moral dilemmas, with Lee Kyung's calm demeanor hiding his hidden agenda and true motives.

Detective Jang Tae-gu starts pursuing Eun-soo after learning of the large-scale drug activities tied to the missing bag.

Eun-soo's husband worsens, requiring more funds, pushing her to agree to a larger drug shipment with Lee Kyung.

During the shipment handoff, a rival dealer ambushes them; Lee Kyung fights back step by step--first dodging thrown objects, then tackling the attacker, disarming him with a knee strike, and escaping with Eun-soo by shoving him into crates.

They deliver the shipment successfully, but the violence alerts Jang Tae-gu, who finds traces at the scene.

Eun-soo decides to expand operations alone for faster money, against Lee Kyung's warning, selling to a new buyer.

The new buyer double-crosses her, stealing the drugs after a tense warehouse meet; Eun-soo chases on foot, grabs a loose pipe, swings it to fend off two thugs who punch her repeatedly, breaks free by kneeing one in the groin, and runs, losing the batch but escaping injured.

Lee Kyung rescues her, bandages her wounds, and reveals part of his past trauma driving his underworld life, deepening their alliance.

Jang Tae-gu raids the warehouse, recovering evidence pointing directly to Eun-soo.

Now, let me take you through the ending of Walking on Thin Ice, scene by scene, as the story hurtles toward its close in a web of desperation, chases, and quiet reckonings.

The chaos erupts in a dimly lit confrontation where Tae Goo, wild-eyed and unhinged, raises his gun at Eun Soo. Her husband, Park Do Jin, lunges forward without hesitation, his body absorbing the bullet meant for her chest. He crumples to the ground in a pool of blood, gasping his last breaths as Eun Soo kneels beside him, her hands pressing futilely against the wound, tears streaming down her face. Tae Goo fumbles to fire again, but his gun clicks empty. He backs away into the shadows, his voice a ragged snarl: "From now on, living will be hell. Just like me." He vanishes into the night.

Days later, at Park Do Jin's somber funeral, Eun Soo stands rigid in black mourning clothes, her face pale and drawn, surrounded by family and flickering candles. Police sirens wail as officers cuff her wrists right there amid the wreaths and incense, dragging her away while her estranged daughter watches from afar with wide, uncomprehending eyes. Eun Soo is hauled into a courtroom, her head bowed under the weight of testimony and evidence, and sentenced to prison.

Meanwhile, Tae Goo, now a fugitive with a scarred face and hunted gait, skulks through back alleys, clutching a bag stuffed with cash and drugs he stole from Eun Soo's home. He lingers outside his son's school, peering through the chain-link fence at children playing, his fingers twitching on the bag strap. His phone buzzes with a video message showing his son bound and gagged, a shadowy figure demanding ransom. Tae Goo's eyes bulge in rage; he smashes the phone and bolts, his mind fracturing as he races back toward Eun Soo, convinced she's behind it.

Eun Soo sits in her prison cell, hunched over yellowed paper, her pen scratching out letter after letter to her daughter--pages filled with pleas for forgiveness, descriptions of her regrets, sealed with trembling kisses. A year passes in montage: iron bars, stale meals, her hair graying at the temples.

Tae Goo bursts into Eun Soo's life again during her release preparations, grabbing her at knifepoint in a rain-slicked parking lot. He forces her into a stolen car, tires screeching as he speeds through city streets, Eun Soo clawing at his arm while he rants about his son and betrayal. Sirens close in. Lee Kyung, grim-faced in a trench coat, pursues in another vehicle, his jaw set. The chase ends in a catastrophic crash: Tae Goo's car slams into a guardrail overlooking a swollen river, metal twisting and glass shattering. Eun Soo stumbles out, coughing, as Kyung arrives. Tae Goo, bleeding from a gash on his forehead, staggers toward her, but Kyung draws his gun and fires--once, twice--into Tae Goo's chest. Tae Goo topples backward over the edge, splashing into the dark churning water, his body vanishing beneath the current.

A year later, skeletal remains wash up on the riverbank-- Tae Goo's bones picked clean, identified by a rusted watch and dental records. News crews swarm the site.

Eun Soo, released and living in a sparse apartment, visits Kyung in prison through a scratched Plexiglas divider. He wears an orange jumpsuit, his once-sharp features softened by time. They speak in low tones: Eun Soo presses her palm to the glass, recounting her choices; Kyung nods, his eyes distant, mentioning regrets, loyalty, the paths they chose. He slides a folder under the partition--evidence dossiers on the Kang Hwi Rim family.

Outside prison walls, Kyung's collected proof detonates: headlines scream of a massive financial scandal, executives in handcuffs, the Kang family empire crumbling under arrests and raids.

Eun Soo, now in modest clothes, unpacks boxes in her new home, a radio droning news of Kyung's triumph. The doorbell rings; Kyung stands there, free, holding a plain bag of stock sale proceeds. Eun Soo takes it, her shoulders relaxing for the first time, murmuring thanks. They embrace briefly, then part with quiet wishes for each other's happiness, Kyung walking away down the empty street.

Alone, Eun Soo prepares to move, folding clothes into suitcases. A report on TV mentions Tae Goo's remains; she pauses, a faint smile crossing her lips. A voiceover echoes: "Gretel pushed the witch into the oven--but were they really okay?"

She reaches into a drawer for a scarf and pulls out packets of hidden drugs, crisp and untouched. Her face freezes, hands hovering, the door creaking open behind her as shadows shift.

Park Do Jin dies from the gunshot wound during the initial confrontation. Tae Goo is shot by Kyung, falls into the river after the car crash, and his skeletal remains are discovered a year later. Eun Soo serves her prison sentence, is released, reunites briefly with Kyung, and discovers the hidden drugs in her home, her future uncertain. Kyung serves prison time, uses evidence to dismantle the Kang Hwi Rim family, is released, returns Eun Soo's money, and parts ways with her. Eun Soo's estranged daughter receives her letters but does not appear in the final scenes; her response remains unknown.
