Be Man's agreed term of five years as a military prosecutor is about to end, and that's when Cha Woo In joins the department as the new military prosecutor.
Knowing that things could get ugly if people find out about Allen's disappearance, No Tae Nam suggests to Yong Moon Gu that he bring in Be Man for the dirty job.
Be Man discovers a new lead that connects Woo In to Allen's abduction. While doing so, he gets an opportunity to work under Chairman No Tae Nam, but the opportunity comes at a heavy cost.
Woo In doesn't hesitate to show Be Man who she really is, and Be Man finds it difficult to get a grasp of the situation. Hwa Young instructs Moon Gu to enlist Tae Nam in the army and takes her son under her wing.
Woo In's words are not convincing enough to persuade Be Man to risk everything to help her. Woo In prepares for a military court case regarding No Tae Nam.
Do Be Man returns to the army as a military prosecutor, and this time, he has a motive to stay. Not only that, he swears that he will assist Woo In in carrying out her revenge. But to Woo In's eyes, Be Man seems to be hiding something.
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.
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.
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.
Bae-man and Woo-in figure out the details regarding 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.
The court's ruling favoured Bae-man and Woo-in, and it's inevitable that there will be internal conflicts within the Patriotic Society. Meanwhile, Woo-in can no longer reach Kang Ha-jun, and a horrifying event takes place at GOP 14.
Bae-man and Woo-in get ready for the trial regarding the shooting spree at GOP. They focus on revealing whether there was hazing involved with the shooter. Meanwhile, Moon-goo seals the deal with IM Defence in order to retrieve the X-File.
With the help of Tae-nam's testimony, the prosecutors regain the upper hand. On top of that, Bae-man and Woo-in now see the situation as a chance to wipe out Patriotic Society once and for all.
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.
