Fuji tries to teach Kawai a lesson about responsibility during their late-night patrol shift. Yamada has his work cut out for him when he finds himself investigating an unrepentant train groper.

The lieutenant decides it's high time he applied more discipline to the station's physical training regimen. Kawai and Fuji spend a night fielding one outrageous police report after another.

Yamada risks becoming a laughingstock when he commits the cardinal sin of losing his police ID. Kawai must figure out how to deal with one of the more disturbing aspects of being on the force.

As the investigation of the high school attack case continues, they need to check the facts from the testimonies of the people involved in the case.

After Makitaka gets the victim's statement and Minamoto and Fuji spot Yasuda leaving the house, it seems the case is finally over. However, for lack of evidence, they still have to be cautious, which basically takes Kawai and company off the rest of the case.
