Tamayama plays the role of Muto Takashi who is a former police detective using illegal methods to solve cases which are difficult to handle by the police while Tanihara plays Muto's buddy and a police detective Kaburagi Wataru and Watabe plays Tamaki Keigo who takes charge of the special missions given to Muto. While exploring the lives of these men, the topic of whether revenge is right or wrong is discussed in this suspense drama.
As this is the first time that the three actors are working together, Tamayama said that he was especially looking forward to learning acting tricks from Watabe since he himself was always labelled as an actor more known for his good looks than his acting since his 20s. However, when the filming actually began, Tamayama was shocked to find out that Watabe wasn't as serious as his public image made him out to be which made Watabe and Tanihara burst out laughing. Tamayama also revealed that when he saw Watabe make the sign of putting up his second finger on both hands, he only came to realise much later that Watabe meant that he wanted to go home by 11pm.
When asked how he has changed as an actor since his 20s, Watabe said that there isn't much he has changed because he still has difficulties figuring how to act. The key difference now is that when looking at his younger colleagues, he finds that there are things he can learn from them which is different from the time he was in his 20s.
