Lin Yuniang travels through time to the ancient era, single-handedly guarding her home for five years to raise a pair of children and support her entire in-law family. Believing her husband had long since passed away, she did not expect him to return in glory with another woman by his side, intending to cast her aside and take away her children. Unwilling to swallow her grievances and submit, Lin Yuniang takes her parents-in-law and family to voluntarily break away from the clan, resolutely divorcing. Relying on her own abilities, she establishes her home and career, cracks multiple difficult cases, and runs businesses to live in peace. By chance, she encounters A Qing, a man who has faced misfortune and possesses a pure disposition, who saves her children. The two slowly accompany each other, step by step uncovering their own backgrounds and pasts, and opening up a brand-new life.
