At the heart of this series is Lee Joo-young, who plays a woman shattered by a phishing scam... and desperate for justice.

Lee Joo-young plays Ha So-min, a young woman who loses her parents to a massive telephone scam. But rather than fall apart, she decides to take revenge. Her weapon? A formidable technology: the deepfake, which she uses to infiltrate the criminal organization responsible for the tragedy from the inside.

He sees Ha So-min walking in the shadows, a knife in her hand, her gaze burning with determination. Her voice rings out like a verdict: «When they get out of prison, people say they’ve paid their debt. But that’s not a punishment… it’s forgiveness bought with time.» These words hint at a story where the law is no longer enough, and where personal vengeance becomes the only way out.

Facing her, Ma Seok-gu (Ji Seung-hyun), ruthless leader of the phishing network, appears in the teaser with a chilling smile, while police cars speed off into the night. The tension mounts, culminating in a striking image: Ha So Min's blood-spattered face, the promise of an uncompromising story.
