Screenwriter Shen Xing was invited to adapt the classic fairy tale, but when researching ancient books, he discovered that all princess stories hide bloody truths. Snow White is actually a queen who uses poisonous witchcraft to take revenge, and Cinderella's glass slipper contains a curse. As she tries to restore history, strange events occur one after another - the crew begins to imitate the death methods in fairy tales. Shen Xing realizes that he has awakened the "Guardian of Stories" who has been sleeping for hundreds of years. Only by rewriting the ending can this fatal "fairy tale trial" be solved.
