The scene is a peaceful suburban setting in an area where trouble rarely calls. Excitement fills the air as a big community event ensues, but in one house there is a studious babysitter quietly reading her books while the radio plays softly and the children in their charge sleeps peacefully upstairs. Nothing seems out of the ordinary until the sitter meets a terrifying and untimely end at the hands of a deranged, usually masked, villain. It's become something of a trope in horror movies over the decades, with gargantuan figures, such as Michael Myers from the infamous Halloween franchise, preying upon unsuspecting teenagers in unfamiliar locations at the dead of night. But for one teenage girl and her family, this nightmare would become a reality.
