Giseok's endless greed runs rampant. Joon-gyeong, Tae-chun, and Eun Yong promise to fight against him to the end, but their different methods to deliver justice violently collide in the final battle. Finally, cartels of power and money begin to collapse.

Push comes to shove, and Gi-seok agrees to play along as Eun Yong's pawn, while gunning for his own comeback. Gi-seok's press conference related to Bawoo Fund succeeds in coinciding with his entire agenda. Corruption and justice swirl and collide, and a gunless war finally begins.

Eun Yong makes Se-hee a secret proposal to motivate Gi-seok, who then sees hope for his ambitions again. Is it money or is it power? Gi-seok finds himself at crossroads. In the end, the disgraced prosecutor makes his final decision.

Eun Yong feels defeated by Chairman Myung's unexpected counterattack. However, he calmly prepares for an opportunity to strike back at Chairman Myung and Gi-seok. Eun Yong sets a trap and waits for the perfect timing. Finally, the opportunity arrives to turn the tide of this war.

Eun Yong offers Gi-seok a deal. As a result, Tae-chun returns to Prosecution Service once his suspension ends. While pretending to lower their heads, Eun Yong and Tae-chun bide time for another counterattack. Meanwhile, Joon-gyeong begins to plot her own cold revenge.

Crisis is another opportunity. Eun Yong sharpens his sword of revenge while in prison. Joon-gyeong wakes up from coma, and Tae-chun is constantly on the move to find leads on his own.

Eun Yong turn himself in, to be the bait. However, because of Chairman Myung's scheme, he is suddenly accused of murder. Tae-chun desperately asks Joon-gyeong for help to save Eun Yong.

Eun Yong barely survives a life-threatening crisis. He calls on Joon-gyeong and Tae-chun to devise a new strategy. The situation takes a new turn when Joon-gyeong speaks at a press conference.
