After violating the warning, she encounters strange things one after another. She discovers that the female ghost in the mirror is not harming her, but is avoiding the evil ghost who is chasing her. As the fear deepens, Lin Wei gradually uncovers the truth about the murder case hidden in the old house three years ago, and is forced to be involved in the road of survival caught between yin and yang. While fighting the evil ghost who seeks life, he helps the female ghost in the mirror to clear her injustice.
