In Bianjing of the Northern Song Dynasty, Ya'an, the daughter of the prime minister, was extremely intelligent since she was a child, and her beauty was even called the best in Tokyo. A palace banquet and her sister's marriage in Huai'an gave her a first glimpse of the coldness of imperial power; the ups and downs of her own destiny made her realize how difficult it is to be a woman.
Jiang Cong, a childhood sweetheart, is as gentle as jade and is willing to protect her with his sincerity; Shen Hui, the number one scholar who meets by chance, seems to have a trace of sincerity behind using her to investigate the case.
On the one hand, there are thrills every step of the way to investigate, and on the other hand, there are many constraints on personal destiny: the beating of imperial power, worldly prejudices, emotional choices...
When the truth of the case is intertwined with personal destiny, can Ya'an break the fate of being a "puppet on a string", find her own way out, and keep the clarity and ideals in her heart? And having determined her own path, who will she choose as her fellow traveler?
