Plot

The story follows Han Kyung-bae (Sul Kyung-gu), a prominent news anchor whose nine-year-old son is abducted. The kidnapper demands a ransom of $100,000 and maintains contact with the boy's mother, Oh Ji-sun (Kim Nam-joo), through a series of phone calls. A police task force, led by veteran detective Kim Wook-jung (Kim Young-chul), is assigned to the case. The investigation is hampered by the kidnapper's ability to evade police traps and his cold, calculated demeanor, which is captured only through recorded phone conversations. As the ordeal stretches from days into weeks, the parents grow increasingly desperate, eventually leading Han Kyung-bae to attempt a direct confrontation with the perpetrator.
