Chen Mo's "Supernatural Detective Agency" specializes in strange cases that cannot be solved by science. A commission broke the peace: when three brides in a row wore the same wedding dress, they all died suddenly of heart attacks, and their white wedding dresses were instantly stained with blood. The investigation pointed directly at the ursed wedding dress made by the embroiderer in the Republic of China - the embroiderer poured resentment into her needlework because of her lover's "betrayal". Chen Mo followed the clues and found Xiu Niang's tomb from ancient books, and found that there was an unfinished half wedding dress hidden in the tomb. When the resentment materializes, he unexpectedly learns that his lover was not betrayed, but died at the hands of a warlord. By collecting historical evidence and restoring the dust-laden truth, can Chen Mo resolve the embroiderer's century-old obsession and completely end the bloody curse?
