In the hustle and bustle of the city, the married life of Jiang Xue and her husband Xie Tingfeng should have been as sweet as honey. However, a series of strange events quietly broke this tranquility. Jiang Xue frequently dreams about the back of a woman in a red dress, looming in the mist. Whenever she wakes up from the dream, her pillow is soaked with tears. At the same time, Xie Tingfeng's behavior became more and more mysterious, and he often came home late, which caused Jiang Xue's uneasiness. Over the weekend, Jiang Xue confided her inner doubts to her best friend Lin Meihua. Lin Meihua, a keen woman who owns a detective agency, decided to help and uncover the truth for Jiang Xue. However, on the night Jiang Xue left Lin Meihua's house, a photo of Xie Tingfeng holding hands intimately with a young girl broke into Jiang Xue's world through WeChat on her mobile phone, instantly igniting her anger and anxiety.
Faced with Jiang Xue's questioning, Xie Tingfeng's explanation seemed feeble, and the relationship between the two dropped to a freezing point. At this moment, Xie Tingfeng disappeared mysteriously, leaving only a series of unsolved mysteries. Lin Meihua's investigation gradually deepened and she discovered that Xie Tingfeng was inextricably linked to a woman named Suman. This woman, Xie Tingfeng's ex-girlfriend, suddenly disappeared on the eve of the wedding, leaving behind a dusty past.
