Xiao Rou, the legitimate daughter of the capital's chief minister, uncovered her husband Zhao Yuan's conspiracy to have an affair with foreign enemies. Instead, she was falsely accused of collaborating with the enemy, and her family was wronged. She was chased and killed while pregnant with Liujia and fell off a cliff. Fortunately, she was reborn as the daughter of a merchant of the same name. When the original owner was murdered by her mother-in-law, Cao, Xiao Rou wisely resolved the crisis, decided to reconcile, gathered her old troops to investigate the unjust case, and joined forces with Imperial City Secretary Zhao Heng to finally expose the evidence of Zhao Yuan and others' crimes and punish them according to law.
