In the bustle of the city, Jiang Xue's married life with her husband, Xie Tingfeng, should have been as sweet as honey. But a series of eerie incidents quietly shattered their peace. Jiang Xue kept dreaming of a woman in a red dress, seen from behind and appearing and disappearing in the mist. Every time she woke, her pillow was soaked with tears. Meanwhile, Xie Tingfeng grew increasingly mysterious, often coming home late and stirring unease in Jiang Xue's heart. One weekend, Jiang Xue confided her doubts to her close friend Lin Meihua. A perceptive woman who ran a detective agency, Lin Meihua decided to help uncover the truth. But on the very night Jiang Xue left Lin Meihua's home, a photo of Xie Tingfeng walking arm in arm with a young woman arrived on Jiang Xue's phone via WeChat, instantly igniting her anger and anxiety.
When Jiang Xue confronted him, Xie Tingfeng's explanation sounded feeble, and their relationship plummeted to freezing point. Then, in a bizarre turn of events, Xie Tingfeng disappeared, leaving behind a string of unsolved mysteries. As Lin Meihua's investigation deepened, she discovered that Xie Tingfeng had countless ties to a woman named Su Man. This woman was Xie Tingfeng's ex-girlfriend, who had vanished on the eve of their wedding, leaving a past long buried in silence.
