A modern female lawyer wakes up in the body of a poisoned bride sent to bring a prince good luck. She rises from her coffin, sues the household, and brings down the prince’s estate, only to be relentlessly pursued by the prince who is faking his illness. Shen Yanqiu, a 34-year-old partner at a top-tier law firm and criminal investigation consultant for the Ministry of Public Security, dies from overwork and is reborn as the illegitimate daughter of a Deputy Minister of War. Her elder half-sister takes her place in a marriage to Prince Xiao, meant to bring him good fortune, and she is poisoned to death just three days after entering the estate. She wakes up in her coffin, feigns death, and puts her lawyer’s instincts to work: filing a petition, investigating her death, and drawing up a divorce agreement. She unexpectedly discovers that Prince Xiao, Pei Yan, is only pretending to be gravely ill. The two strike a secret deal: she investigates the old case concerning his birth mother, and he lets her divorce him. But as they solve cases together and join forces to topple the Crown Prince’s faction, Pei Yan falls for her completely and tears up the divorce papers. In the end, Shen Yanqiu chooses to stay and opens Dayin’s first women’s law school, changing the law.
