Director Pascal Plante was intrigued by the serial killer groupies, who pop up out of nowhere for each serial killer that makes the news, and are seen rooting for him at their trials. He wondered who were these people, but as he researched cyber crimes, he chose to reflect the technological aspect of our society into his thriller, thus making the protagonist a very modern psychopath.
Director Pascal Plante purposefully took the story away from the actual serial killer to the groupies to give it a female point of view, which is quite rare in thrillers.
