Growing up in a border town, Qiao Yan (Zhao Liying) became a well-known actress after years of hard work, but was careful along the way under heavy pressure. With an anonymous blackmail message, a dusty past becomes her new shadow. Meanwhile, her sister (Xin Zhilei), who lost contact with her years ago, suddenly shows up. Things may seem coincidental, but there is a bigger crisis hidden behind. The movie is adapted from Zhang Yueran's novel.
