Set in Nagoya, Japan in 2019, it begins with Mitsuyo, an elderly woman who lives alone. She receives a phone call from a girl who pretends to be her daughter, asking for money. Having experienced fraud a few years before, Mitsuyo immediately calls the police and helps arrange the arrest of a 14-year-old receiver named Kazuto. Kazuto worked with a caller named Daisuke and a lookout named Toyama. Having grown up in the same poor neighborhood, Daisuke and Toyama believed that phone fraud was an honorable way to recover the "dead money" of wealthy elderly people and return it to the society. Believing underage receivers like Kazuto to be expendable, they made a killing in their scams. Not long after Kazuto's arrest, Toyama gets arrested. Daisuke attends Toyama's trial to make sure that he doesn't talk. Then Mitsuyo appears as a witness. Listening to her testimony, Daisuke is astonished to learn that she was deceived years ago by his fraud call, which resulted in her husband killing himself in shame. Daisuke finally realizes that phone fraud robs people not only of money, but also family bonds and even their lives.
