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.

Kawai just wants to go home after a long shift and get some rest, but things don't seem to go according to plan. A witness to an attack on a girl comes along and someone will need to do a composite sketch of her testimony.

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.
