Shen He, the young minister of Dali Temple, was unjustly imprisoned, and the Shen family collapsed overnight. The only daughter, Shen Suining, disguised herself as a man and sneaked into Dali Temple as an official, vowing to find out the truth. A series of secret room murders occurred in Chang'an City. The deceased were all related to his father's old case. Each corpse held the word "Crane" written in blood in its hand. The new minister of Dali Temple, Pei Changan, invited her to investigate the case together, while Supervisor Si Tianzheng Xie Wuqi also kept aloof in the dark. On a full moon night, murderous intent reappears. As she gets deeper into the puzzle, she discovers that her father's injustice is just the tip of the iceberg of a court conspiracy, and the people she trusts the most around her may have their own agendas.
