Following the perplexing demise of Nam Gi-seok, Nam Gi-jun steps from the shadows, driven by a singular purpose: to unearth the one responsible, regardless of the price.

Following the trail of Gi-seok’s assault, Ji-jun uncovers the scheme’s true source, a revelation that compels him to enact a regulation he himself instituted over a decade prior.

Though his father had taken every precaution, Gu Jun-mo remained blind to the danger closing in. Driven by frustration and desperation, he resolved to confront Gi-jun personally.

Driven by a desperate need to save his son, Chairman Gu delves further into the details of Gi-seok’s assault. Meanwhile, following Jun-mo’s attack on his companions, Gi-jun confronts Jun-mo and his forces.

Gi-jun soon discovers that Jun-mo was merely the first of his troubles. A gang war erupts when Chairman Lee begins to suspect a deeper, more insidious hand in the recent disturbances.

Cha Yeong-do initiates his carefully laid scheme. With Lee Geum-son's ascent to power, Gi-jun finds himself beset by treachery, peril, and a desperate pursuit of answers.

Having surmounted every impediment, Geum-son now initiates his final plan. Will Gi-jun manage to thwart him, or will he be consumed by the effort?
