Be Man and Woo In are called to a disciplinary hearing after publicly making a huge mistake. However, they still believe that there is a need for the investigation to continue. As they continue with the investigation in their own ways, the true identity of the so-called Mine Hero disgusts both Be Man and Woo In.

Justice is closing in on Won Ki Choon as people related to the case come forward with the truth. Be Man also pressures Ki Choon to do the right thing and stand against No Hwa Young. Eventually, Ki Choon meets face-to-face with Hwa Young and requests the proper treatment that he deserves. Meanwhile, Hwa Young tries to deal with the risky situation in her usual way.

After the shocking death of Won Ki Choon, Be Man and Woo In turn to the next best option and go through crucial evidence that Ki Choon has been keeping. Be Man believes that there is something fishy going on at Hong Moo Sup’s official residence and sets him as his next target. However, Woo In is not on board with the idea of an aggressive investigation and tells Be Man to back off.

Be Man finally confronts Hwa Young face-to-face, and at the same time, Woo In greets Moon Gu at one of the IM’s offices. With their plans on the verge of being exposed, the two start gearing up for their next move. Meanwhile, to make up for his mistake, Be Man tries to maintain the right to investigate the bullying case. However, Hwa Young already has her plans to manipulate the court.

Be Man and Woo In figure out the details regarding Commanding General Hong’s abuse of power right before the trial. Although they make their utmost effort to prove Shin’s innocence, it is hardly likely that the trial will proceed with fairness. Meanwhile, Woo In gets a phone call from an unexpected caller.

With the help of Tae Nam’s testimony, the prosecutors regain the upper hand. On top of that, Be Man and Woo In now see the situation as a chance to wipe out Patriotic Society once and for all. Meanwhile, Moon Gu’s plans to become IM’s owner fail when an unwelcome guest shows himself at the shareholders’ meeting.

The sound of battle has now faded away, and the military prosecutors and Tae Nam are brought to the emergency room. Only time will tell whether they will survive the critical condition. Meanwhile, Moon Gu makes a last-ditch effort to escape conviction. Be Man and Woo In also prepare for the last battle of the war.
