Plot

Imamiya (Fumino Kimura) is a detective who deals with fraud and scam cases. She arrests Kaji (Mahiro Takasugi), who is involved in a voice phishing case. Imamiya and her colleagues do not know who is at the top of the voice phishing group. Detective Tezuka (Kenichi Endo) suggests that they should let Kaji walk free and see if he will lead them to the top of the group.
