Qiao Yan (Zhao Liying), who grew up in a small border town, became a well-known actress after years of hard work, but she was cautious all the way under heavy pressure. With an anonymous blackmail message, a dusty past became her new shadow. At the same time, her sister (Xin Zhilei), who had lost contact many years ago, suddenly appeared. The matter seemed coincidental, but there was a greater crisis behind it. The film is adapted from Zhang Yueran's novel "Da Qiao Xiao Qiao".
