The inspiration for the creation of this film came from a Japanese case seen by the producer David Higgins. Female students began hunting old men who sought to date underage girls on the Internet. Once the girls got in touch with each other online, She and her friends will set up ambushes at the dating site. Higgins is quickly attracted by the interesting case, because it is difficult to determine who is the hunter and who is the prey. Therefore, he hoped that a 14-year-old girl would do it all alone.
Higgins began to look for drama writers rather than film screenwriters to create scripts, because this kind of film not only requires plot, but also pays attention to the shaping and portrayal of characters. He found Brian Nelson, a leading figure in the Los Angeles theater industry. Nelson is one of the founders of the Huang Zhelun Writers Association. Many of his stage plays have won awards. Higgins and Nelson worked together to complete the script in two months, and the director's choice fell on David Slade, who won attention with MV and commercial television.
