Sagi no Ko

Set in Nagoya, Japan, Sagi no Ko follows Mitsuyo, an elderly woman who faces a fraudulent call from someone pretending to be her daughter. After previously experiencing a scam, she takes action by notifying the police, which leads to the arrest of Kazuto, a young participant in the scheme. The narrative unfolds as Kazuto works for Daisuke and Toyama, who rationalize their criminal activities as a means to reclaim 'dead money' from the wealthy.

As the story progresses, the film highlights the consequences of scamming, particularly through Mitsuyo's testimony during Daisuke's trial. Her revelations expose the deep personal impact of fraud, including a tragic backstory involving her husband's suicide. This emotional confrontation prompts Daisuke to recognize the destructive nature of his actions, illustrating how phone fraud extends beyond financial loss to affect families and lives irreparably.
