Wang Yao, a female anti-narcotics police officer in southern Xinjiang, dies on a mission. When she opens her eyes, she has become an orphan in ancient times, having just lost her father.
With no money in her pocket and her home in shambles, she has barely come down from the mountain when she encounters a child whose lifesaving money has been stolen. A bright idea strikes her, and she stages a stone interrogation to catch the thief.
She is taken in by the pitiful Doudou and his grandmother, and they join forces to get by.
In this era, women who want to become constables are met with pointing fingers and endless gossip.
But Wang Yao has always loved solving cases and standing up against injustice. She has no desire to be cooped up at home doing housework.
She steels herself and joins the yamen as a female constable, solving cases and catching thieves as one problem after another comes her way.
Fortunately, she meets someone who truly cares for her, understands and supports her work on cases, and never tells her to stay obediently in the inner quarters.
She doesn't want to marry a high official or a prince, nor is she chasing wealth and status. She only wants to rely on her own abilities to protect her family and uphold the justice she believes in.
