Ippei (Sousuke Ikematsu), a handler in the police dog section, returns to the forensics department after his morning training as usual with his partner, Oliver, a police dog. While super volunteer Konishi-san (Sato Koichi) is talking about finding the body of a girl who has been missing for 11 years, a call comes in for dispatch due to a fraud at a certain house. Ippei and Oliver investigate, relying on the scent left behind in the house, but Oliver finds something extraordinary.
