With eyes on the target, Tae-jun sets the wheels in motion. Seon-yeong looks into a suspicious death, and sees Lee Ji-eun return as her chief of staff.

Seon-yeong requests the truth from Tae-jun, and joins forces with him to go after Lee Chang-jin. Hui-seop deals with a betrayal.

Shaken up by Chang-jin's tactics, Seon-yeong and Tae-jun search for more evidence against him. Choe Gyeong-cheol launches an investigation.

A scandal threatens to derail Tae-jun. Gyeong-cheol stays out of Hui-seop's political plays. Seon-yeong puts Joojin Chemical under further scrutiny.

Things seem to be back on track for Seon-yeong and Tae-jun as they prepare for the parliamentary inquiry. Feeling the heat, Hui-seop retaliates.

While Tae-jun works on a new plan to turn Chang-jin and Hui-seop against each other, Yun Hye-won and Han Do-gyeong try to pin down a mole.

Needing more information on Hui-seop's slush funds, Tae-jun and Seon-yeong place Oh Won-sik in a sticky situation.

Knowing the consequences, Seon-yeong holds a press conference. Hui-seop treads on thin ice with Sung Yeong-gi. Won-sik runs out of options.

Vowing to finish what Tae-jun started, Seon-yeong pushes for a special probe into the slush funds, but Hui-seop tries to stop her.

While Hui-seop does whatever he must to save himself, Tae-jun, Seon-yeong and their staff get ready for his hearing. Gyeong-cheol seeks justice.
