After the mysterious death of Hwarang’s president, Oh Jae-Yeol, the criminal organization was plunged into turmoil as factions within it fought for control. This power vacuum was quickly exploited by the black society, who moved in to take over from the weakened Hwarang, leading to widespread chaos. The Hwarang executives, eager to seize power for themselves, began to plot against each other while also battling against the growing influence of the black society. Unfortunately, civilians began to suffer at the hands of the ruthless newcomers, but the police and politicians were unable to help, as they too had been infiltrated by the black society. In the midst of this upheaval, Baek-Han Yu, a former special forces unit, was shattered when his mother was brutally murdered by the black society after she had tried to drive them out of her neighborhood. Driven by a burning desire for revenge, Baek-Han Yu sets out on a mission to bring down the black society.
