In the turbulent times of the late Eastern Han Dynasty, Liu Bei's two wives and a concubine Qilan (Sun Li) were trapped in Cao's camp. Guan Yu (Donnie Yen) surrendered to Cao Cao (Jiang Wen) for loyalty, but he could not forgive Cao Cao's ambition to control the Han Dynasty and hoped to return to Liu Bei's side. Cao Cao admired Guan Yu's military talent and benevolence, and tried to persuade him with the interests of the people of the world. When Yuan Shao led his army to attack Cao, Guan Yu killed Yan Liang in battle and was awarded the title of Marquis of Han Shou Ting. He also formed a comrade-in-arms friendship with Zhang Liao (Shao Bing). After Cao Cao sent the two Liu ladies back, he added aphrodisiacs to Guan Yunchang's wine, hoping to make him have an illicit relationship with Qilan. Guan Yunchang had a secret crush on Qilan, a fellow villager, and even killed soldiers for her. This relationship was eventually blocked by the uncle-sister-in-law relationship. Guan Yunchang, who had come to his senses, took Qilan to Liu Bei, breaking through many checkpoints along the way, leaving behind the eternal legend of "passing five checkpoints and beheading six generals"...
