Plot
Lee Kang-hee, an editor at an influential conservative newspaper, raises congressman Jang Pil-woo to the position of leading presidential candidate using the power of the press; behind this is his secret deal with the paper's biggest sponsor, Mirae motors.

Ahn Sang-goo, a political henchman who supported Lee and Jang, gets caught pocketing the record of the sponsor's slush fund, resulting in a dismembered hand. Woo Jang-hoon, an ambitious prosecutor, starts to investigate the relationship between Jang and the sponsor, believing that it's his only chance to make it to the top. While getting down to the brass tacks of the case, Woo meets Ahn, who has been methodically planning his revenge. The war between the one blinded with power, the one hell-bent on vengeance, and the one eager for success begins, as prosecutor Woo becomes the "inside men" to expose the dark scheme of Lee and Jang to the people.
