Determined to turn the tables, Park Dong-ho attempts to assassinate the president. But Jeong Su-jin swiftly steps in to execute her own agenda.

Armed with leverage, Kang Sang-un approaches Dong-ho with an offer. Dong-ho's attempt to initiate a no-holds-barred investigation encounters a hiccup.

Dong-ho risks everything to reinitiate the investigation before the president awakes. In response, Su-jin resorts to a ruthless tactic to turn the tides.

Dong-ho turns his attention to the presidential election campaign - and sets a trap for Su-jin. He later enlists questionable support for a leg up.

Facing calls to resign, Dong-ho confronts Su-jin privately. He soon debates Jo Sang-cheon, where the issue of North Korea plagues Dong-ho's campaign.

Although Su-jin gains possession of Dong-ho's Achilles' heel, Dong-ho reveals he has a trick up his sleeve. Su-jin then hones in on Park Chang-sik.

Dong-ho enacts a scheme to completely expose Su-jin to the public. But she aims to turn Lee Jang-seok against Dong-ho before her hearing begins.

With Su-jin in the prime minister's seat, Dong-ho meets with Chairman Kang in a ploy to take her inner circle down - forcing her to plan her own revenge.

Su-jin coaches Sang-un to give a damning testimony against Dong-ho and sway public opinion. Facing impeachment, Dong-ho turns to Chairman Kang.

Dong-ho exposes himself to bring his foes to justice, putting himself at risk for prosecution. In turn, Su-jin stops at nothing to have Dong-ho arrested.

Su-jin derails the investigation into Daejin and turns the scrutiny back onto Dong-ho. As a strike threatens Dong-ho's power, he uses his silver bullet.

Dong-ho's final act forces Su-jin to make the ultimate choice - reveal the truth or go down in disgrace. In the end, will justice prevail?
