Natsuki Sahara (Takeru Sato) is a rookie detective. He is assigned to work as the #1 detective for the Ginza Police Station, but his father Akimura Shimao (Atsuro Watabe) also works there as a detective. Natsuki Sahara does not like his father at all. After his parents divorced when he was 13-years-old, he was raised by his grandparents. Meanwhile, Akimura is a bit eccentric and a playboy with the ladies. This is in direct contrast with his son who is poor when it comes to dating. Akimura feels bad for his son for divorcing when he did. He tries to help him at work, but has difficulties approaching him in the right way.
