By imperial decree, Lin Zhaoya—descendant of a loyal and martyred family—is married to the distant frontier general Lu Jingshen. On their wedding night, Lu publicly declares he already has a wife and forces his new bride to become a concubine. Unwilling to accept the humiliation, Lin Zhaoya tears off her bridal veil and phoenix crown and storms the palace gates to dissolve the marriage.
But the wedding farce hides a darker plot. Lu’s mistress Liu Qinghe, heavily pregnant, forces her way in with a forged imperial edict, blocking Lin from returning home. In a hidden compartment of the western villa, Lin discovers the old northern seal, ledgers of compensation silver, and secret letters. Ten years ago the Lin family army held the pass to the death—yet reinforcements were stopped thirty li outside by a false order. The entire clan’s martyrdom was no accident; it was cold-blooded murder.
Lin races to Black Stone Camp, rescues her brother Lin Chengyan who has been imprisoned for a decade, clears the old case, and restores the heroic spirits to the ancestral temple. In the end she takes up the Lin family’s former post and plants the Lin banner once more on the northern frontier.
