 A group of devil-may-care teenagers discover they ve mistakenly called upon the Prince of Darkness in this flashy horror story. A handful of high school students have been entertaining themselves on weekends by playing an elaborate role-playing game in which they impersonate witches, warlocks, and other magical beings. One weekend, they decide to up the ante by breaking into the school and using the building s nooks and crannies to make the competition more challenging. One of the teens has brought along a book of magic spells, and they decide to throw some incantations into the games to make things more interesting. What the kids didn t count on is that the spells actually work, and soon the role-players have unleashed an unspeakable and dangerous force.
