Akari Mita may be emotionless but she's a super housekeeper who completes everything she is asked to do perfectly. But, be careful when telling her what to do; she does everything you ask her to, literally!
There is a new directive that stipulates all interrogations by the cops should be recorded. The cops gather at their headquarters to ostensibly be trained on what this means for their work. They are told to interrogate suspects correctly, but witness one who seemingly regrets nothing. When the interrogation does not go well the cops are instructed to be ready for more training especially for the novice in them. Then an emergency occurs.
