大川と小川の時短捜査

Directed by Kana Matsumoto

With Yutaka Matsushige, Gaku Hamada, Kaho, Takaya Sakoda and Ron Mizuma

The president of an IT company is found dead. The cause of death is believed to be an overdose of medication for a chronic illness, but the possibility of murder emerges since potassium and other substances were found in the body. Ogawa, unfamiliar with the investigation, asks for help from Okawa, a former detective who now works for the police department. The "large-and-small duo", who are uneven in appearance and personality, take on the challenge of getting to the bottom of a difficult case.
