Plot content:

The innocent and sweet 14-year-old girl Hailey met the 32-year-old photographer Jeff on the Internet. The two met in a cafe and met. The conversation was very pleasant. Hailey took the initiative to go to Jeff's house and let him take artistic photos of herself, and Jeff happily obeyed. After chatting and drinking, Jeff suddenly fell dizzy and fell to the ground. When he woke up, he found that he was tied up.

It turns out that Haili came prepared, that is, to punish pedophiles who seduced underage girls on the Internet. Haley searched the house for evidence of Jeff's wrongdoing and performed a castration on him. Midway, the neighbor's wife came to visit, but Haili also managed to fool her. As Haley's punishment plan unfolds step by step, Jeff's true face gradually emerges.

Creative background:

The inspiration for this film came from a Japanese case that producer David Higgins had seen. A schoolgirl began hunting older men seeking dates with underage girls online, and once a girl made contact online, she and her friends would set up an ambush at the rendezvous. Higgins is quickly attracted to the interesting case because it is difficult to determine who is the hunter and who is the prey. So, he hoped that a 14-year-old girl could do it all alone.

Higgins began to look for drama writers rather than film screenwriters to write 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 scene. Nelson was one of the founders of the Henry Hwang Writers Association and directed many of his award-winning stage plays. Higgins and Nelson worked together to complete the script within two months, and the choice of director fell on David Slade, who had gained attention with music videos and commercial television.
