While out visiting clients, Sales Department Manager Taisuke Yamagata receives an urgent phone call: "Just get back here right now!"

Apparently, Taisuke has been branded as the murderer of a female college student, with his real name and photo already leaked online, setting off a massive internet firestorm.

The killer was allegedly bragging about the crime on social media, but the account was somehow mistaken for Taisuke's. Though he initially remains optimistic that the misunderstanding will clear up quickly, the impersonation is so cunningly executed that not a single person believes his innocence—not his employer, not his friends, not even his family...

In just a few short hours, the entire population of Japan has become his enemy. Hunted by everyone everywhere, Taisuke continues his desperate flight.
