In the turbulent days of 19th-century Joseon Korea, a cruel and tyrannical nobleman named Jo Yoon seeks to consolidate his power and wealth by exploiting the common folk. He aims to secure his position by eliminating any threats, including family members who could challenge his claim. Meanwhile, Dolmuchi, a humble butcher struggling to survive, finds himself thrust into the conflict when his family is torn apart by Jo Yoon's ruthless actions. Desperate and vengeful, Dolmuchi transforms from a downtrodden peasant into a fierce warrior seeking justice.

Dolmuchi joins a band of noble outlaws known as Kundo, who relentlessly target the corrupt aristocracy and redistribute stolen wealth to the oppressed. United by their common cause, the group wages a daring campaign against exploitation and tyranny. Each member of Kundo brings unique strengths to their rebellion, and together they ignite a spark of hope among the downtrodden populace. As Dolmuchi grows into his role as a formidable fighter, the battle between the impoverished and the elite intensifies, setting the stage for a dramatic clash that will determine the fate of all involved.
