A divine goddess transmigrates into the body of Bai Li, the dying wife of the Xiao family. Just as she is falsely accused of being a demoness and about to be sacrificed, she awakens and is reborn. Together with her husband, Xiao Jin, an Inspector of the Mysterious Cases who has been away for three years, she investigates a series of bizarre mysteries, including a fox demon wreaking havoc, a dream tapir stealing souls, and a flower demon committing murders. As the truth unfolds, they discover that demons are not necessarily evil; it is the greed and obsession in human hearts that are truly terrifying. Xiao Jin's identity as a white wolf demon, Lan Wuzheng's conspiracy, and the mysterious figure known as the Moon Venerable gradually come to light. Amid these dangerous trials, Bai Li also uncovers the truth about her origins as a divine goddess.
