Chief of Staff
The real political players behind the spotlight take a dangerous gamble. Super Adviser Jang Tae Joon heads towards the peak of power and fiercely struggles for survival. Jang Tae Joon worked as the chief aide to Lawmaker Lawmaker Song Hee Sub. He now returns as a lawmaker and achieves the height of his power.
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.
