The ancient house is deep and dark, with the hanging door ajar. An old case that has been gathering dust for more than ten years is hidden under layers of dusty family veils.
Jin Xuan, a calm and taciturn prison prosecutor, is good at investigating mysterious cases and has insight into people's hearts. He was called back to his hometown to investigate an unsolved murder case. He stepped into this intricate old house of a wealthy family and was careful not to be coerced by family ties. He only wanted the truth to be settled.
Jin Xi, who comes from a century-old family, looks gentle and calm on the outside, but is tough and sober on the inside. She is an underappreciated sideline girl in the family. She has witnessed the undercurrents in the house since she was a child, and she knows full well that the glamor of this mansion is full of lies and sacrifices. When the old case happened, she was the one who witnessed it. She was forced to keep silent and bury the secret deep in her heart.
A hanging door separates the inner and outer worlds. Inside the door, the clan is united, covering up from top to bottom, and lies are passed down from generation to generation; outside, Jinxuan is holding a file to investigate the case, insisting on tearing apart the disguise. The two met, tested each other, and became suspicious of each other. Jinxuan suspected that Jinxi was deliberately concealing the truth, but Jinxi did not dare to trust external officials easily, for fear that if the truth was revealed, it would lead to a catastrophe.
As the investigation deepens, strange things in the house emerge one after another: strange noises in the middle of the night, forged testimonies, deliberately destroyed physical evidence, and endless obstructions from the tribesmen. In one dangerous situation after another, the two went from being wary of each other to trusting each other. Jin Xi finally put aside her worries and quietly provided Jin Xuan with secret clues; Jin Xuan also saw her arrogance under her meek skin, unwilling to succumb to the shackles of the clan.
The truth of the old case involves family interests, grudges from the past, and even the transaction of human lives. Behind the hanging door lies blood and sacrifice.
The clan uses bloodline coercion and rumors to pressure them, trying to seal the truth forever. Jinxuan holds the law, and Jinxi knows the secrets of the house. The two work together to break through the shackles, push open the hanging door that has been hidden all year round, and let the buried injustice come to light again.
The fog cleared and the hanging door opened wide.
They not only solved an old murder case, but also broke free from the feudal prison that trapped a generation, and found each other's glimmer of light in the dark abyss.
