Shen Yan, an ancient book restorer, stepped into the "Qihe Hall" deep in the ancient alley because of an anonymous letter and half a yellowed wedding letter. This old house, filled with a cool and fragrant breeze, hides unknown secrets - the red candles sway in the middle of the night, the faded wedding dress flutters for no reason, and the shadow of a woman in a bright red wedding dress always lingers in the dimmed candlelight, her voice as ethereal as tears.
With the restoration of half of the marriage book, an injustice that had been buried by time gradually emerged: a hundred years ago, when Miss Su Wan of the Su family was wearing a wedding dress and waiting to be married, she was framed and buried in a dry well. Her soul was bound by the marriage book and trapped in the old house for a hundred years. When Shen Yan was sorting out ancient books, he not only encountered strange events frequently, but also discovered that the "lone copy" left by his employer was actually a blood letter recording the conspiracy of that year.
On one side is the encroaching ghostly resentment, and on the other side is the old hatred hiding murderous intent. Shen Yan is forced to be involved in this entanglement that spans life and death. When the marriage certificate is completely pieced together, and the truth cuts through the fog like a sharp blade, he must choose between uncovering the truth about the murder and quelling the resentment of the dead souls. Every inch of Qihe Hall is witnessing this redemption and reckoning that is a century late.
