During the reign of Emperor Wencheng, the Tiger Guards secretly controlled Chang'an, growing in power. Hu Yiáng, a government official from Huainan County, is called to the capital by Emperor Ji Wuyang to eliminate corrupt officials. General Yan Fengshan, leader of the Tiger Guards, refuses to relinquish power and plots to split the nation and make himself king. He hides his forces in "Soldiers' Alley," waiting for the right moment to strike.

With the emperor’s support, Hu Yiáng allies with General Gu Yu, swordsman Ye Zheng, painter Bai Wan, and scholar Xie Ziling. Together, they use their wisdom to destroy "Soldiers' Alley" and stop Yan Fengshan’s plan, restoring peace to Chang'an.
