Hee Woo and his colleagues finally take down Kim Seok Hoon using his wife and son's corruption and Kim Seok Hoon's own unethical life. Cho Tae Sub now seeks a new nominee for the next prosecutor general. Meanwhile, Hee Woo, Sang Man, and Hee A hear about JQ Constructions becoming available for acquisition soon and begin their plan to make a bid.

Seok Kyu, the new Chief Prosecutor, tells Hee Woo to take his hands off of the Kim Seok Hoon case and transfers him to a different team. Hee Woo knows that Cho Tae Sub is the one behind this order, but he decides to keep going with his plan to take down the people closest to Cho Tae Sub himself. When Hee Woo goes after Park Dae Ho, Cho Tae Sub starts to strike back at Hee Woo.

After taking down Cho Tae Sub's allies and underlings, Hee Woo resigns from the prosecution. In a surprise move, he announces his candidacy for the National Assembly in the same constituency as Cho Tae Sub himself.
