Voice of a Murderer

Sang-woo, the 9-year-old son of celebrated news anchor Han Kyung-bae, vanishes without a trace. A ransom call soon follows, demanding 100,000 dollars in exchange for his life. The family and police rush to respond, racing against time as fear sharpens their resolve.

The kidnapper's demand marks the start of a high-stakes countdown as investigators scramble to act. With a public crisis looming, the police and the family push for leads while resources are mobilized. The tension stretches across the city as every movement becomes a potential clue.

Police assemble a secret investigative task force and a forensic team to keep up with a case that seems to move faster than anyone can follow. The coordinated effort signals the seriousness of the probe and the willingness to pull every string for Sang-woo's return. The clock ticks relentlessly as detectives track leads through a shifting web of possibilities.

The Bastard's Voice taunts with a cold, emotionless tone, never lingering on a live call and always staying a step ahead. He alternates exchange sites across the city, complicating the investigators' attempts to predict his next move. His calm patience reveals a calculating mastermind who baits fear as a weapon.

Detective Kim Wook-jung is seized from inside a car trunk and subjected to torture, a brutal display of the kidnapper's control. The assault tests the detective's resolve and heightens the urgency of the pursuit for Sang-woo's family. This act also signals the personal risk investigators face when confronting the kidnapper.

The family endures a storm of calls from the kidnapper, who continues to mock them while demanding more money. Each message amplifies their fear and grief, making the search feel personal and intimate. The fear drives them to rely on the authorities while coping with the unbearable wait.

Investigators weigh suspects, including Kyung-bae's former best friend Lee Jae-joon, who bears a heavy grudge. Yet Jae-joon's alibi initially appears airtight, keeping him in the running without a clear link. The case remains unsettled as the police push for further corroboration.

A forensic audio expert reveals that one of the so-called proofs of life could be a manipulated recording. This revelation forces a recalibration of how the case is publicly handled and what might be trusted as evidence. The investigators adjust their strategy to avoid leaping to conclusions based on altered audio.

Kyung-bae agrees to a public appeal to mobilize the city against the kidnapper's shadowy game. The televised appeal seeks to amplify public pressure for information and heighten accountability. The move underscores how personal tragedy becomes a national concern.

A new target arises when the kidnapper directs another delivery near Lotte World, intensifying the chase. Kyung-bae steps forward, joining the dangerous exchange in a bid to preserve hope for Sang-woo. The exchange setup places both family and investigators in a perilous, uncertain moment.

Kyung-bae places the money at the specified site and waits for a reunion that never comes. The failed exchange forces the investigators to confront the grim possibility of Sang-woo's fate. The days stretch into weeks, heightening the city's fear and resolve to find the truth.

On the 44th day, authorities discover Sang-woo's body near a Han River park. The discovery shatters the family's hope and drives the city into renewed vigil and mourning. The tragedy marks a turning point that shifts public attention toward justice and accountability.

Kyung-bae returns to his anchor chair to report Sang-woo's death to the nation. He also shares a recording of the kidnapper's voice, turning personal loss into a public cry for accountability. The broadcast seals the end of the nightmare and reinforces the drive to seek justice.

The city grapples with fear while investigators press forward in pursuit of truth. The tragedy is framed as a cautionary tale about safety, media attention, and the costs of unresolved crime. Justice remains the collective goal as clues slowly come into sharper focus.
