In June 2015, Kyogoku (Karasawa Toshiaki) suddenly woke up after being in a coma for 30 years due to an accident during an investigation. It has been a year since he and the young detective, Mochizuki Ryota (Kubota Masataka) of Yokohama Chuo Police Precinct, drove the violent criminal called Kagura as well as the organisation Kyogoku was pursuing 30 years ago to destruction and closed this chapter from the past. Kyogoku and Ryota are still living together in the same place. Although Ryota and Yui (Sasaki Nozomi) have been dating for close to a year, Kyogoku stubbornly refuses to approve their relationship. In this one year, Kyogoku and Ryota have led the police in solving numerous heinous crimes. Ryota has also undergone an unbelievable transformation from a year ago. The investigation methods of the two of them occasionally create trouble. But because their arrest rate and contributions are the highest in the Kanagawa area right now, their maverick, overbearing behaviour is tolerated. They are the gstadium jumper and skinny machoh pair of the Yokohama Chuo district.
