Synopsis: The son of TV anchor Han Jingpei (Xue Jingqiu) is kidnapped, and the kidnapper (Jiang Dongyuan) demands a ransom of 654.38 billion won, so Jingpei can't bargain. Jing Pei and his wife Shan Zhi (Kim Nam Joo) are very anxious, so they have to call the police, and the police soon launched an investigation. The police's high-tech investigation methods have no effect on cunning criminals at all. The only useful evidence is the voice recorded by the kidnapper on the phone. A deep, unemotional voice. The case has not progressed, and the Jingpei couple don't even know the life and death of their son. So Jing Pei decided to come forward himself and secretly meet the kidnappers.
