While celebrating Christmas at a cabin in the woods, a group of high school students are stalked by a psychotic killer obsessed with horror movie icons.
The main character is not outright abused, however, one of the main plot points is that he was shown very graphic horror movies as a child that had traumatic effects. There is also a scene where a step-mother figure is quite harsh, but it is partly out of concern for the kid and the fact the dad let's him keep watching the horror films.
