Mauxma has an article on The Neon Demon. It is in Italian. Via the google translator, gives the following info on the plot:
Jesse is a young aspiring actress and model who dreams to become a star of haute couture once decided to move to Los Angeles. Here, however, nothing is as it seems: the girl will be captured from the cloudy and patinated environment that surrounds it, to finish some overwhelmed and paying its expenses the price of success, in a plot that involves not only shocking photo shoots and catwalks, but also voodoo , cannibalism and much more.
While the film is slated to be released in the US in March 2016, there is speculation that the film may turn up at Cannes based on Nicolas Winding Refn’s Best Director award there in 2011. We will have to wait until April for Cannes Film Festival announcements.
