A series of murders on a moonlit night rocked the court, and a powerful man with bad deeds mysteriously hanged himself on the night of the full moon. There was no trace at the scene, and the Ministry of Punishment was helpless.
The entire Shen family was wronged and destroyed, and the orphan girl Shen Wuyi was seen by the world as a smart and transparent man who believed in the law, but secretly he was a moonlight sharp blade controlled by secret techniques and his hands were stained with blood without knowing it. She was adopted by the Taifu Su Yanci. Everyone praised the Taifu for his kindness, but no one saw the conspiracy. Since the secret skill was activated at the age of sixteen, her consciousness has been sleeping every full moon and she has become the villain's execution tool. Seven murders have been committed by her.
In order to clear up the old family case, Shen Wuyi planned to make a name for himself in the capital. Xie Linyuan came to visit:
"I have heard for a long time that the girl is good at solving suspicions and that murderous cases on a moonlit night bring trouble to the government and the public. I hope that she will join the Criminal Department and help me find the real culprit."
As the candlelight spread over the file, she raised her eyes and asked, "Master Xie, if the evidence of guilt falls on someone you don't want to harm, what will you do?"
Xie Linyuan looked cold and stern: "In front of the law, there is no personal relationship."
Working together day and night, he admired her character and talent, but was also surrounded by many doubts, and her reason and heart were repeatedly pulled apart. She pursued justice all her life, but she didn't know that she was the murderer being hunted by the whole country.
The Mid-Autumn Festival is approaching, and the Ministry of Punishment has laid out a dragnet. The villain wants to activate the secret technique when the guard is at its highest, forcing her to commit murder in public, and blame all the sins on her.
When the bloody full moon rises into the sky, the murderer the iron-faced criminal wants to catch is his beloved confidant; Shen Juan, who is dedicated to seeking justice, is burdened with a heinous crime that he did not commit. Trapped in a fateful situation set by others, the two of them can only work together to break the situation and break free from the shackles.
Determination: To stop evil with evil is not the right way, only the human heart determines what is good and what is evil
