Veteran doctor Tanaka has spent years participating in fraud with a pharmaceutical company. When Kato, who is close to Chief Saeki, reports him and leaves him cornered, Tanaka tries a hypnosis app he bought on a whim and successfully brainwashes Saeki into believing his misconduct never happened. Fascinated despite barely understanding hypnosis, he devours research on mind control at work and realizes that his first success involved implanting a false perception. Determined to destroy Saeki and Kato together, he exploits Saeki’s feelings for Kato and appears to engineer a successful confession—but everything is part of his scheme, and an oblivious Kato gets carried away. For Tanaka, the thrill of hypnosis and brainwashing has become impossible to resist.
