Lin Yanxue’s father, Lin Jingyuan, is the garrison commander at Yanmen Pass. Framed by the treacherous official Gao Song for “colluding with the enemy and betraying the nation,” he is condemned unjustly. Lin Yanxue sets out to clear her father’s name. With Xiao Ce’s wholehearted help, the two gather irrefutable evidence that Gao Song has secretly colluded with the Turks and embezzled army provisions. After overcoming countless dangers, they capture Gao Song and travel together to the capital to petition the emperor.
With the help of loyal officials such as Lord Wang, they present the evidence to the emperor at the morning court. Gao Song’s excuses are thoroughly refuted, his crimes exposed, and he is sentenced to execution after the autumn harvest. All his accomplices are also brought to justice. Lin Jingyuan’s name is cleared, and he is posthumously enfeoffed as Marquis Zhenguo. His memorial tablet is placed in the Shrine of Loyal Martyrs, where the people honor him.
Afterward, Lin Yanxue and Xiao Ce return to Yanmen Pass and carry on Lin Jingyuan’s legacy, protecting the frontier together. The people of Yanmen Pass now live in peace and prosperity, and the border is secure. As they safeguard their country, the two remain by each other’s side. Their journey, which began with an unjust accusation, ends in a heartwarming conclusion: the loyal are vindicated, the nation is at peace, and the lovers stay together.
