The story takes place in the last years of the Joseon Dynasty. It was a time of chaos and treason. Those who stole hooks were executed, and those who stole the country were made marquises. The people lived in dire straits. Stone (played by Ha Zhengyu) who lived in Naju was a lowly butcher. One day, he was instructed by his master Zhao Run (played by Jiang Dongyuan) to swing a knife to kill people. Zhao Run was a local nobleman. He was highly skilled in martial arts, but cunning and fierce. Unfortunately, Stone's action failed, and his family was brutally killed. At the moment when his own life was hanging by a thread, he was rescued by the Jiyi Mountain Bandits. Because of the tyranny of the rich and powerful, many overwhelmed people fled into the mountains and became bandits, and even raised the banner of "doing justice for the heavens" to rob the rich and help the poor. Stone met heroes such as Ming Gong Maxiang, Lu Jiaotou Daihao, and Liu Shiheshang, and embarked on a bloody life. And Zhao Run and others who have done many evil things will also pay the price for their evil deeds...
