Undercover agent Yuko Kuremachi appears to be nothing more than an ordinary housemaid, but in reality, she's a highly skilled operative who has solved numerous major cases. Her current target is a malicious organization involved in illegal raw meat trafficking—a criminal operation hidden beneath layers of deception. Successfully infiltrating the group's mansion under the guise of a domestic worker, Yuko gradually uncovers its inner workings. Using intense physical interrogation on a low-ranking member named Ichikawa, she extracts the location of the illicit meat. But her actions are more than just an investigation—they mark the beginning of a dangerous game.
